INPUT AND OUTPUT PROCESSING
Please note that the material on this website is not intended to be exhaustive.
This is intended as a summary and supplementary material to required textbook.
INTRODUCTION
Most computer programs spend very little processing time in obtaining input and producing output.
Most of the work goes into the processing in between. The exception to this generalization is non-
browser-based graphical user interfaces (GUIs). In these programs, often over 50% of the code can be
dedicated to user input and output. In browser-based user interfaces, the browser does a lot of the work
for you.
Input/output (I/O) comes in two flavors: interactive and non-interactive. Interactive I/O involves
prompting the user for the input and displaying the output on the user's monitor. Non-interactive I/O
involves reading and writing files, which for us will be text files.
INTERACTIVE I/O
The majority of interactive I/O is accomplished in C++ using cin and cout. For now all interactive I/O
comes from and goes to the console window. Recall that in order to use cin and cout we have to
#include <iostream>.
The cin input stream views the input the user types as if the data came from a text file. But, cin ignores
as data all whitespace characters: the newline, the tab, and the space. As a result cin does some input
formatting for the program, and only assigns non-whitespace data to the input variables.
If the user is entering several data items on one line (in the console window), cin will wait for the user to
press the newline (Enter or Return) key before it will process the line of input data.
The input stream can consist of any array of characters, representing: integers, decimals, strings, single
characters, .... Each array of characters is delimited by whitespace characters, and cin will interpret any
of the whitespace characters as a delimiter (with some exceptions, of course).
When we invoke cin we always have to specify a variable in which to place the user input; that variable
must have a type. And, cin is very persnickety about types. If cin is expecting an integer, it will not read
an alphabetic character; it will generate an error condition. In the following code snippet cin will expect
to see a single character, an integer, a decimal, and a string, in that order.
char yOrN;
int userID;
double hourlyWage;
string lastName;
...
cin >> yOrN >> userID >> hourlyWage >> lastName;
If the user typed the last name for the userID, cin will flag an error and not continue to read the input
stream until your program deals with that error (see below).
The cout output stream has a lot more variety to it; cout is aware of the types of variables passed to it,
and will format them accordingly, unless your program specifies another format to use. When thinking
about the arrangement of your program's output, consider each string of output characters as a field, and
the contents of each line of output as an array of fields. T.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

What is Python?
Welcome to Python!
Python is a high-level programming language, with applications in numerous
areas, including web programming, scripting, scientific computing, and artificial
intelligence.
It is very popular and used by organizations such as Google, NASA, the CIA and
Disney.
Python is processed at runtime by the interpreter. There is no need to compile
your program before executing it.
Interpreter: A program that runs scripts written in an interpreted language such as Python.
The three major version of Python are 1.x, 2.x and 3.x. These are subdivided
into minor versions, such as 2.7 and 3.3.
Backwards compatible changes are only made between major versions; code
written in Python 3.x is guaranteed to work in all future versions. Both Python
Versions 2.x and 3.x are used currently.
Python has several different implementations, written in various languages.
The version CPython is used further.
Python source files have an extension of .py
3. 3
BASIC CONCEPTS IN PYTHON SUMIT S. SATAM
The Python Console
First Program:
On IDLE (Python GUI)
The Python Console
Python console is a program that allows you to enter one line of python code,
repeatedly executes that line, and displays the output. This is known as REPL –
a read-eval-print loop.
To close a console, type in “quit()” or “exit()”, and press enter.
Ctrl-Z : sends an exit signal to the console program.
Ctrl-C : stops a running program, and is useful if you’ve accidentally created a
program that loops forever.
>>> print("Hello Universe")
Hello Universe
>>> quit()

BASIC CONCEPTS IN PYTHON SUMIT S. SATAM
Simple Operations
1. Simple Operations can be done on console directly.
* : Multiplication / : Division
2. Use of parentheses for determining which operations are performed
first.
3. Minus indicates negative number
4. Dividing by zero in Python produces an error, as no answer can be
calculated.
In Python, the last line of an error message indicates the error’s type. In
further examples only last line of error is written.
>>> 2 + 2
4
>>> 5 + 4 – 3
6
>>> 2 * (3 + 4)
14
>>> (-7 + 2) * (-4)
20
>>> 11/0
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
11/0
ZeroDivisionError: integer division or modulo by zero
5. 5
BASIC CONCEPTS IN PYTHON SUMIT S. SATAM
Floats
Floats are used in Python to represent numbers that aren’t integers. Extra
zeros at the number’s end are ignored.
A float can be added to an integer, because Python silently converts the
integer to float. This conversion is the exception rather the rule in Python –
usually you have to convert values manually if you want to operate on them.
Other Numerical Operations
Exponentiation
The raising of one number to the power of another. This operation is
performed using two asterisks.
Quotient & Remainder
Floor division is done using two forward slashes. ( // )
The modulo operator is carried out with a percent symbol. ( % )
>>> 2**5
32
>>> 9** (1/2)
3.0
>>> 20 // 6
3
>>> 1.25 % 0.5
0.25
6. 6
BASIC CONCEPTS IN PYTHON SUMIT S. SATAM
Strings
A String is created by entering text between two single or double quotation
marks.
Some characters can’t be included in string, they must be escaped by placing
backslash before them.
Manually writing “n” can be avoided with writing the whole string between
three sets of quotes.
Simple Input & Output
In Python, we can use print function can be used to process output.
To get input from user, we can use input function. Which prompts user for i/p.
Returns what user enters as a string (with contents automatically escaped).
>>> print(1 + 1)
2
>>> input("Enter here:")
Enter here:222
222
>>> """System: Please Enter Input
User: Enters Input
System: Gives Output."""
'System: Please Enter InputnUser: Enters
InputnSystem: Gives Output.'

BASIC CONCEPTS IN PYTHON SUMIT S. SATAM
String Operations
Strings in python can be added using Concatenation using “+” operator.
Strings also can be multiplied.
Strings can’t be multiplied by other strings.
Strings also can’t be multiplied by floats, even if the floats are whole numbers.
>>> “Hello ” + ‘Python’ (works with both types of
quotes)
Hello Python
>>> “2” + “2”
22
>>> "2" + 3
TypeError: cannot concatenate 'str' and 'int' objects
>>> "Sumit" * 3
'SumitSumitSumit'
>>> 4 * '2'
'2222'
>>> '27' * '54'
TypeError: can't multiply sequence by non-int of type 'str'
>>>"PythonIsFun" * 7.0
TypeError: can't multiply sequence by non-int of type 'float'
8. 8
BASIC CONCEPTS IN PYTHON SUMIT S. SATAM
Type Conversion
You can’t add two strings containing numbers together to produce the integer
result. The solution is type conversion.
>>> int("2")+int("3")
5
>>> float(input("Enter a number:"))+float(
input("Enter Another Number:"))
Enter a number : 42
Enter Another Number : 55
97.0

BASIC CONCEPTS IN PYTHON SUMIT S. SATAM
Variables
A variable allows you to store a value by assigning it to a name, which can be
used to refer to the value later in the program.
To assign a variable, “=” is used.
Variables can be used to perform operations as we did with numbers and
strings as they store value throughout the program.
In Python, variables can be assigned multiple times with different data types as
per need.
For Variable names only characters that are allowed are letters, numbers and
underscores. Numbers are not allowed at the start. Spaces are not allowed in
variable name.
Invalid variable name generates error.
Python is case sensitive programming language. Thus, Number and number
are two different variable names in Python.
>>> x=9
>>> print(2*x)
18
>>> x=123
>>> print(x)
123
>>> x='String'
>>> print(x+'!')
String!
>>> 2ndNo = 22
SyntaxError: invalid syntax
10. 10
BASIC CONCEPTS IN PYTHON SUMIT S. SATAM
Trying to reference a variable you haven’t assigned, causes error.
You can use the del statement to remove a variable, which means the
reference from the name to the value is deleted & trying to use the variable
causes an error.
Deleted variables can be reassigned to later as normal.
You can also take the value of the variable from user input.
>>> foo = 'string'
>>> foo
'string'
>>> bar
NameError: name 'bar' is not defined
>>> del foo
>>> foo
NameError: name 'foo' is not defined
>>> foo=input("Enter a number: ")
Enter a number: 24
>>> print foo
24
11. 11
BASIC CONCEPTS IN PYTHON SUMIT S. SATAM
In-Place Operators
In-place operators allow you to write code like ’x = x + 3’ more concisely,
as ‘x +=3’. The same thing is possible with other operators such as - , * , / and
% as well.
These operators can be used on types other than number such as
strings.
Many languages have special operators such as ‘++’ as a shortcut for ‘x+=1’.
Python does not have these.
>>> x=25
>>> x+=30
>>> print(x)
55
>>> x = "Learn"
>>> print(x)
Learn
>>> x+= "Python"
>>> print(x)

Single Line Comments
Multi-line Comments
The print() Function
Displays the string value inside the parentheses written in the program on the
screen.
You can also use this function to put a blank line on the screen; just call
print() with nothing in between the parentheses.
The input() Function
Waits for the user to type some text on the keyboard and press ENTER.
This function call evaluates to a string equal to the user’s text, and the previous
line of code assigns the myName variable to this string value.
You can think of the input() function call as an expression that evaluates to
whatever string the user typed in.
#This Single Line Comment
print(‘Hello World!’)
'''
This is another type of comment
This is multi-line comment.
'''
myName = input()
13. 13
BASIC CONCEPTS IN PYTHON SUMIT S. SATAM
The len() Function
You can pass the len() function a string value (or a variable containing a string),
and the function evaluates to the integer value of the number of characters in
that string.
Example:
The str(), int() and float() Functions
If you want to concatenate an integer such as 21 with a string to pass to
print(), you’ll need to get the value '21', which is the string form of 21. The str()
function can be passed an integer value and will evaluate to a string value
version of it, as follows:
The str(), int(), and float() functions will evaluate to the string, integer, and
floating-point forms of the value you pass, respectively.
>>> str(21)
'21'
>>> print('I am ' + str(21) + ' years old.')
I am 21 years old
>>> len('hello')
5
>>> str(0)
'0'
>>> str(-3.14)
'-3.14'
14. 14
BASIC CONCEPTS IN PYTHON SUMIT S. SATAM
TEXT AND NUMBER EQUIVALENCE
Although the string value of a number is considered a completely different
value from the integer or floating-point version, an integer can be equal to
a floating point .
>>> 42 == '42'
False
>>> 42 == 42.0
True
>>> 42.0 == 0042.000
True
Python makes this distinction because strings are text, while integers and
floats are both numbers .
>>> float('3.14')
3.14
>>> float(10)
10.0
>>> int('42')
42
>>> int('-99')
-99
>>> int(1.25)
1
>>> int(1.99)
