This document discusses decision making structures in Python, including if, if-else, and if-elif-else statements. It provides the syntax and examples of using each type of statement to evaluate conditions and execute code blocks based on whether the conditions evaluate to True or False. The if statement executes code if the expression is true, if-else adds an else block for when the expression is false, and if-elif-else allows checking multiple expressions and executing the block for the first one that is true.

Creating decision structures of a program
The document discusses different types of decision structures in programs, including IF and SELECT CASE statements. It describes the syntax of basic IF...THEN statements used to evaluate conditions and execute code accordingly. IF statements can contain multiple commands that run when the condition is true, and use ELSE to handle false conditions. ELSEIF statements allow evaluating additional conditions if the first is false.
Conditional statement
The document discusses conditional statements in programming. Conditional statements check an expression and execute code depending on whether the expression is true or false. The main conditional statements are IF statements and IF-ELSE statements. An IF statement executes code if the expression is true, while an IF-ELSE statement executes the IF code if true and the ELSE code if false. Examples are provided to illustrate how to use IF and IF-ELSE statements to check conditions and produce different outputs.
If and select statement
This document discusses conditional statements in VB.NET, including if statements, if-then-else statements, if-then-elseif statements, nested ifs, and select case statements. It provides the syntax and examples of each type of conditional statement. The if statement executes code depending on a boolean expression being true or false. Select case statements allow checking multiple mutually exclusive conditions and executing different code blocks.
Computer programming 2 Lesson 9
This document discusses different types of decision making statements in Java including if, if-else, if-else-if, nested if, and switch statements. It provides the syntax and flow for each statement type along with examples to demonstrate their usage. Key decision making structures covered are basic if statements with conditional blocks, if-else statements that execute alternative code blocks based on boolean expressions, and if-else-if statements that allow testing multiple conditions in a single structure. The document also reviews nested if statements, switch statements for equality checks, and rules that apply to switch statements.
Computer programming 2 - Lesson 7
This document discusses different types of decision making statements in Java including if, if-else, if-else-if, nested if, and switch statements. It provides the syntax and flow for each statement type along with examples to demonstrate their usage. Key aspects covered include using boolean expressions to determine program flow, nesting if statements, using break to terminate switch cases, and applying the switch statement to variables of specific data types only.

Java chapter 3
The document discusses different types of statements in Java including decision and repetition statements. It covers if, if-else, switch statements for decision making and while, do-while, for loops for repetition. It provides examples of each statement type and discusses when to use each one. It also covers block statements, comparing characters and strings, and avoiding infinite loops.
10. switch case
This document discusses switch-case statements in C programming. It explains that switch-case allows programmers to make decisions from multiple choices based on an integer expression. Each case must have a different constant value. The break statement is used to terminate a switch. Expressions and char values can be used in cases if they are constant. Switch statements are useful for menu-driven programs. They have advantages over if-else statements in that compilers generate jump tables, making switches faster at execution time.

Python files / directories part16
The document discusses reading from and writing to files in Python. It describes the write() and read() methods for writing strings to and reading from open files. It also covers opening files with different modes like "a" for append and "w" for overwrite. Examples are given to illustrate writing a line of text to a file, reading the first 10 bytes of a file, and reading each line of a file using a loop.
Python Classes and Objects part14
The self parameter is used to access variables that belong to a class from within its methods. It refers to the current instance of the class and must be the first parameter of any method in the class. For example, a Person class defines self in the __init__() method to set name and age attributes, and in the myfunc() method to print the name attribute. We can create objects of a class, modify or delete their properties using keywords like del, and delete objects by deleting all references to them using del.
Python Classes and Objects part13
The document discusses classes and objects in Python. A class defines attributes like data members and methods that characterize objects of that class. The class acts as a blueprint to create objects. The __init__() method is a special method that is called when new objects are instantiated and allows assigning values to object properties. It takes self as the first parameter, which refers to the current object instance and is used to access variables belonging to the class.
Python files / directories part15
The document discusses file handling in Python. It explains that the open() function is key for working with files in Python and takes a filename and mode as parameters. It describes different modes for opening files, including 'r' for reading, 'a' for appending, and 'w' for writing. The document also covers getting file attributes after opening and the close() method for closing files.
Python functions part12
This document discusses passing lists and tuples as arguments to functions in Python. It provides examples of passing a list to a function, which allows the function to iterate through the list. It also discusses variable-length arguments using an asterisk, and provides an example of a function that accepts additional unnamed arguments as a tuple. Finally, it discusses anonymous functions in Python using the lambda keyword, and provides an example of defining and calling an anonymous function.
Python functions part11
This document discusses different types of arguments that can be passed to functions in Python, including required arguments, keyword arguments, default arguments, and passing lists as arguments.
Required arguments must be passed to a function in the correct positional order. Keyword arguments allow the caller to identify arguments by parameter name instead of position. Default arguments assume a default value if no value is provided for that argument in the function call. Passing a list as an argument allows a function to accept a variable number of values. Examples are provided to illustrate each type of argument.
Python functions part10
Functions allow you to reuse code by defining blocks of code that can be called. Functions can take parameters and return values. To define a function, use the def keyword followed by the function name and parameters in parentheses. The code block is indented and starts with a colon. To call a function, use the function name followed by parentheses. Arguments can be passed into functions when calling them to provide input.
List view5
The document discusses ArrayAdapter methods for modifying and working with lists in Android. It lists methods for adding and removing items from the list, clearing the list, notifying of data changes, and getting items and positions. It also mentions abilities of ArrayAdapter like filtering and sorting the list. Questions at the end ask to explain the helper methods and provide an example for one method.
Python decision making_loops_control statements part9
The range() function in Python is used to generate sequences of numbers. It returns a sequence of integers from start to stop-1 by default or allowing for specification of the start, stop, and step values. Examples show using range() in for loops to print numbers from 0 to 5 with the default start of 0 and increment of 1, from 2 to 6 with a specified start of 2, and from 2 to 30 incrementing by 3. The document also provides examples of calculating a factorial using for and while loops with range().
List view4
The document discusses Toasts in Android, which are popup messages that provide feedback to users without taking focus away from the current activity. It explains that Toasts are lightweight and non-interactive, and can display text for a predefined short or long duration. An example is provided using the makeText() method, which requires a Context, message string, and duration as parameters. The document also outlines how to specify toast duration and customize toast location on screen.
List view3
The document discusses ListView and AdapterView in Android. It notes that ListView derives from AdapterView, which are views that use adapters. It lists subclasses of AdapterView like AdapterViewFlipper and GridView. It then focuses on ListView and how to add event handling through an onItemClickListener, providing an example of setting one on a ListView to react to clicks and display a Toast with the item position.
Python decision making_loops_control statements part8
The document discusses the break, continue, and pass statements in Python. It provides examples of how each statement can be used in for and while loops. The break statement terminates the current loop and continues execution after the loop. The continue statement skips the rest of the current loop iteration and continues to the next one. The pass statement is used when a statement is syntactically required but no operation needs to be performed.
Python decision making_loops part7
This document discusses various types of loops in Python including for loops, while loops, and nested loops. It provides examples of using a for loop to iterate through a list and print each item, as well as using nested while loops to check if a number is prime. The document also briefly mentions loop control statements like break, continue, and pass that can change the normal execution flow of a loop.
Python decision making_loops part6
1. Decision making statements like if-else statements and nested if statements allow programmers to execute different code based on certain conditions being true or false.
2. A nested if statement is when an if statement is placed inside the true block of an outer if statement, allowing for more complex conditional logic.
3. The main difference between if-else and nested if statements is that if-else provides two execution paths based on a single condition, while nested if allows evaluating multiple conditions in sequence to determine the correct execution path.
List view2
This document discusses using built-in layouts and ListView in Android. It provides code to populate a ListView with sample data using an ArrayAdapter. The ListView is defined in an XML layout file and populated in the activity code. Built-in layouts like simple_list_item_1 provide easy-to-use templates for common widgets like TextView and simplify ListView implementation.
List view1
The document discusses the key components of a ListView in Android, including the ListView itself, list items, and data for each item. It explains that list items can contain simple or complex layouts. The data comes from adapters that act as intermediaries between the data source and ListView. Adapters fetch data, create layouts for each item, and return items to the ListView. Common data sources are arrays, content providers, and database cursors. The main adapter types are ArrayAdapter for arrays and SimpleCursorAdapter for content providers and cursors.
Python operators part3
This document discusses membership and identity operators in Python. Membership operators like 'in' and 'not in' evaluate to True if a variable is or is not found in a specified sequence. Identity operators like 'is' and 'is not' evaluate to True if two variables point to the same object or not. The document also provides examples of using these operators and defines their behavior.
Python operators part2
This document summarizes common operators in programming languages. It describes arithmetic, comparison, assignment, logical, bitwise, and membership operators. For each type of operator, it provides examples of common operators like addition, subtraction, equality, assignment, AND, OR, and examples of their usage. The document is intended as an introduction to different types of operators that can manipulate and compare values in programming.
Python part1
Python was developed by Guido Van Rossum in 1991 and named after Monty Python. It is an interpreted language that is commonly used for web development, software development, mathematics, and system scripting. Some key features of Python include: indentation to indicate code blocks rather than brackets; using # for comments; storing text in string variables and numeric values in number variables; and deleting objects using del statement.

Python decision making part4
- 1. Prof. Neeraj Bhargava Vishal Dutt Department of Computer Science, School of Engineering & System Sciences MDS University, Ajmer
- 2. Introduction • Decision making is anticipation of conditions occurring while execution of the program and specifying actions taken according to the conditions. • Decision structures evaluate multiple expressions which produce TRUE or FALSE as outcome. You need to determine which action to take and which statements to execute if outcome is TRUE or FALSE otherwise.
- 4. If Statement • It is similar to that of other languages. The if statement contains a logical expression using which data is compared and a decision is made based on the result of the comparison. Syntax if expression: statement(s)
- 5. Example var1 = 100 if var1: print "1 - Got a true expression value" print var1 var2 = 0 if var2: print "2 - Got a true expression value" print var2 print "Good bye!“ #Output 1 - Got a true expression value 100 Good bye!
- 6. IF...ELIF...ELSE Statements An else statement can be combined with an if statement. An else statement contains the block of code that executes if the conditional expression in the if statement resolves to 0 or a FALSE value. The else statement is an optional statement and there could be at most only one else statement following if. Syntax The syntax of the if...else statement is − if expression: statement(s) else: statement(s)
- 7. Example var1 = 100 if var1: print "1 - Got a true expression value" print var1 else: print "1 - Got a false expression value" print var1 var2 = 0 if var2: print "2 - Got a true expression value" print var2 else: print "2 - Got a false expression value" print var2 print "Good bye!" #Output 1 - Got a true expression value 100 2 - Got a false expression value 0 Good bye!
- 8. The elif Statement The elif statement allows you to check multiple expressions for TRUE and execute a block of code as soon as one of the conditions evaluates to TRUE. Similar to the else, the elif statement is optional. However, unlike else, for which there can be at most one statement, there can be an arbitrary number of elif statements following an if.
- 9. Syntax if expression1: statement(s) elif expression2: statement(s) elif expression3: statement(s) else: statement(s) Note: Core Python does not provide switch or case statements as in other languages, but we can use if..elif...statements to simulate switch case
- 10. Example var = 100 if var == 200: print "1 - Got a true expression value" print var elif var == 150: print "2 - Got a true expression value" print var elif var == 100: print "3 - Got a true expression value" print var else: print "4 - Got a false expression value" print var print "Good bye!" #Output 3 - Got a true expression value 100 Good bye!
