Python language for loop with example

In this tutorial, we will discuss the concept of Python language’s for loop with example

In this post, we are going to learn how to  use for loop in Python language

Python for loop is used to repeat a block of codes up to limited time to keep the computer running a program. We can use any python object such as string, array, list, tuples, dictionary in for loop.

Example
var – variable used to read each element form the range of elements
range – the range of elements in python (list, tuple,String any others)

0
1
2
3
4
5

This program prints numbers from 0 to 5

program 2

When the above code is executed it produces the folowing result
1
2
3
4
5
When the above code is executed it produces the folowing result
0

2
4
6
8
10

Program 3
When the above code is executed it produces the folowing result

1
3
6
10
15
21
28
36

This program sums up every number  from 0 to 10 as in the example
Program 4
When the above code is executed it produces the folowing result

for i in range(10):
    print(i);
else:
    print("Program finished")

When the above code is executed it produces the folowing result

0
