This document provides an industrial training presentation on Python programming. It introduces Python, explaining that it is an interpreted, object-oriented, high-level programming language. It then covers why Python is used, its basic data types like numbers, strings, lists, dictionaries, tuples and sets. The presentation also discusses Python concepts like conditionals, loops, functions, exceptions, file handling, object-oriented programming and databases. It concludes that Python supports both procedural and object-oriented programming and can be universally accepted. References for further reading are also included.

3. What is Python
 Python is an interpreted, object-oriented, high-level
programming language with dynamic semantics.
 Python's simple, easy to learn syntax emphasizes readability
and therefore reduces the cost of program maintenance.
 Python supports modules and packages, which encourages
program modularity and code reuse.

4. Why We Use Python
 Large Standard Library
 Embedded
 Open source
 Object Oriented Language
 Interpreted Language
 Speed
 Easy Programming Language
 GUI Programming Support

5. Data Types
 Number
 String
 List
 Dictionary
 Touple
 Sets

6. Data Types
NUMBERS –
1. Integer Number Data Type
2. Floating Number Data Type
3. Complex Number Data Type
DICTIONARY -
A dictionary is a collection which is ordered, changeable and does
not allow duplicates.
Dictionary are used to store data value in key:value pairs.
Ex. dict = {1: “a”,2:“b”}.

7. Data Types
LIST –
List is a collection of different values of different types of items.
The item in the list are separated with the comma(,) and enclosed
with the square brackets[].
a=[1,2,"sham","ram",21.5]
STRING –
Sequence of letters enclosed in quotes is called string or string
literal or constant.
Python supports both form of quotes i.e.
‘Hello’ , “Hello”

8. Data Types
SETS -
A type of array, which is unordered as well as unindexed. It
doesn’t allow Duplicate members.
Ex. Set1 = {“ram”, “shyam”}
TUPLES –
“t = (1,2,3,one)”.
A simple immutable ordered sequence of items
Items can be of mixed types, including collection types.

9. Python Loops
Python has two primitive loop commands:
 While loops
 For loops
 While loop - The while loop we can execute a set of statements as
long as a condition is true.
 For loop - A for loop is used for iterating over a sequence (that is
either a list, a tuple, a dictionary, a set, or a string).
 This is less like the for keyword in other programming languages,
and works more like an iterator method as found in other object-
orientated programming languages.
 With the for loop we can execute a set of statements, once for each
item in a list, tuple, set etc.

10. Python Function
 A function is a block of code which only runs when it is called.
 You can pass data, known as parameters, into a function.
 A function can return data as a result.
 Python a function is defined using the def keyword
 Example :
 Def statements - def name_of_function(arg1,arg2):
call ‘ name_of_function()’.

11. Conditional Statements
‘If -elif –else’
statements -
If test
expression:
Body of
if
elif
test expression:
Body of elif
else:
Body of else
‘If – else’
statements -
if test
expression:
Body of if
else:
Body of else
-
‘If’ statements -
num = -1
if
num > 0:
print(num, "is
a positive
number.")
print("This is also
always printed.")

12. Python Operators
 Operators are special symbols in Python that carry out arithmetic
or logical computation. The value that the operator operates on is
called the operand.
Example : >>>>2+3
5
Operators that Python Language supports are:
 Arithmetic Operators
 Assignment Operators
 Comparison Operators
 Logical Operators
 Identity Operators
 Membership Operators
 Bitwise Operators.

13. Errors and Exception Handling
 Errors :Errors are the problems in a program due to which the
program will stop the execution. On the other hand, exceptions
are raised when some internal events occur which changes the
normal flow of the program.
Two types of Error occurs in python.
 Syntax errors
 Logical errors (Exceptions)
 Exception handling : Python has many built-in exceptions
that are raised when your program encounters an error
(something in the program goes wrong). When these
exceptions occur, the Python interpreter stops the current
process and passes it to the calling process until it is handled. If
not handled, the program will crash.

14. Database Handling
 . The DBMS is a software system that enables you to create,
store, modify, retrieve, and otherwise handle data from a
database. Such systems also vary in size, ranging from small
systems that simply run on your personal computer to larger ones
running on mainframes.
 Establish a connection to your database of choice.
 Create a cursor to communicate with the data.
 Manipulate the data using SQL (interact).
 Tell the connection to either apply the SQL manipulations to the
data and make them permanent (commit), or tell it to abort those
manipulations (rollback), thus returning the data to the state before
the interactions occurred.
 Close the connection to the database.

15. File Handling
 File handling is an important part of any web application.
Python has several functions for creating, reading, updating,
and deleting files.
 The key function for working with files in Python is
the open() function.
 The open() function takes two parameters; filename, and mode.
 There are three different methods (modes) for opening a file:
 "r" - Read - Default value. Opens a file for reading, error if the
file does not exist
 "a" - Append - Opens a file for appending, creates the file if it
does not exist
 "w" - Write - Opens a file for writing, creates the file if it does
not exist

16. Object Oriented Programming
(OOP)
OOP is basically very useful in future work. Basically, this is
defined in to two categories Class and Object.
 Class: Class is a type of category of overall type. They can be
a person, animal in other words it’s a broad.
 Object: From Class we get Object. These are instance of a
class.
 Inheritance: In this concept, we have two types of class
‘Child Class’ and ‘Parent Class’. As we know in
human the meaning of inheritance is obtaining the qualities,
some effects or any other things
child gain from their parents and from grandparents. Same in
Python the Child Class
inheritance the properties of Parent Class or functions of
Parent Class. This is the very basic concept of Inheritance.

17. Conclusion
 Python supports both function-oriented and structure-oriented
programming. It has features of dynamic memory management
which can make use of computational resources efficiently. It is
also compatible with all popular operating systems and
platforms. Hence this language can be universally accepted by
all programmers.
 • Implementation to develop Python based GUI Application
 • Directly interacted with OS using Python Programming.
