When should I use for loops in Python?

For loops in Python are ideal for iterating over sequences like lists, tuples, or strings. They allow you to execute a block of code multiple times.

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 using while loops instead?

While loops are better when you don't know the number of iterations in advance. Use for loops when you have a definite range or collection to iterate over.

Are there any performance differences between for and while loops?

Generally, for loops are more efficient for iterating over collections, while while loops can be more flexible. However, the difference is often negligible for small datasets.
