When should I use loops in Python?

When should I use loops in Python?

You should use loops in Python when you need to repeat a block of code multiple times, such as iterating over a list.

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

Sure! Here's a simple example using a for loop:

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

This will print numbers 0 to 4.

What about while loops? When should I use those?

While loops are useful when you want to repeat a block of code as long as a certain condition is true. For example:

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

Are there any performance considerations when using loops?

Yes, performance can vary. For large datasets, consider using list comprehensions or built-in functions for efficiency.
