What are the differences between for and while loops in Python?

What are the differences between for and while loops in Python?

In Python, a for loop iterates over a sequence (like a list or a string), while a while loop continues until a condition is false.

Can you give me an example of each?

Sure! A for loop example: for i in range(5): print(i) prints numbers 0 to 4. A while loop example: i = 0; while i < 5: print(i); i += 1 does the same.

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 depends on a condition.

Are there any performance differences between them?

Generally, performance differences are minimal, but for loops can be more efficient for iterating over sequences due to their optimized nature.
