What are for loops and how do they work in programming?

For loops are a control flow statement that allows code to be executed repeatedly based on a condition. They are commonly used to iterate over a sequence, such as a list or a range of numbers.

Can you give me an example of a for loop in Python?

Sure! Here's a simple example in Python:

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

This will print the numbers 0 to 4.

What is the difference between a for loop and a while loop?

A for loop is typically used when the number of iterations is known, while a while loop is used when the number of iterations is not predetermined and depends on a condition.

Are there any common mistakes to avoid when using for loops?

Yes, some common mistakes include off-by-one errors, modifying the loop variable inside the loop, and not initializing the loop variable properly.
