# Nested Loops in Python Programming

Hello dear readers! Welcome back to another edition of our tutorial on Python. In this tutorial guide, we are going to be studying about the nested loops in Python.

Python allows for the use of a loop inside another loop. This tutorial post contains a few examples to illustrate the concept.

# Syntax

The syntax for a nested loop is as follows -

```for iterating_var in sequence:
for iterating_var in sequence:
statements(s)
statements(s)```

The syntax for a nested while loop statement in Python is as follows -

```while expression:
while expression:
statement(s)
statement(s)```

A final note on nested loops is that you can put any type of loop inside of any other type of loop. For example a for loop can be inside of a while loop and vice versa.

## Example

The following example makes use of a nested for loop in finding the prime numbers from 2 to 100 -

```#!/usr/bin/python

i = 2
while(i < 100):
j = 2
while(j <= (i/j)):
if not(i%j): break
j = j + 1
if (j > i/j) : print i, " is prime"
i = i + 1

print "Welcome to Web design tutorialz!"```

### Output

The following below is the output of the above example -

```2 is prime
3 is prime
5 is prime
7 is prime
11 is prime
13 is prime
17 is prime
19 is prime
23 is prime
29 is prime
31 is prime
37 is prime
41 is prime
43 is prime
47 is prime
53 is prime
59 is prime
61 is prime
67 is prime
71 is prime
73 is prime
79 is prime
83 is prime
89 is prime
97 is prime
