Answer
A statement that allows a set of instructions to be performed repeatedly is known as a looping or iteration statement. Python provides looping statements in the form of for and while loop.
These statements enable a program to perform a set of instructions repeatedly. For example,
num = 3
while num > 0 :
print num
num = num - 1
