Nested Loops
Nested loops are one loop inside the another loop. For example, we can write a for loop inside a while loop or a for loop inside another for loop. Such loops are called ‘nested loops‘.
Syntax
for [first iterating variable] in [outer loop]: # Outer loop ... statements ... for [second iterating variable] in [nested loop]: # Nested loop ... statements ...
Example Nested Loops in Python:
#to display stars in right angles triangular form for i in range(1,11): for j in range(1,i+1): print('*', end='') print() #Output: * ** *** **** ***** ****** ******* ******** ********* **********
