What are loops in Python?

What are loops in Python?

Loops in Python are used to execute a block of code repeatedly. The two main types are 'for' loops and 'while' loops.

Can you give me an example of a for loop?

Sure! Here's a simple example:

for i in range(5):
    print(i)

This will print numbers 0 to 4.

What about while loops?

A while loop continues to execute as long as a condition is true. For example:

count = 0
while count < 5:
    print(count)
    count += 1

This will also print numbers 0 to 4.

When should I use a for loop instead of a while loop?

Use a for loop when you know the number of iterations in advance, and a while loop when the number of iterations is uncertain.
