When should I use a for loop in programming?

When should I use a for loop in programming?

You should use a for loop when you need to iterate over a sequence, like a list or a range of numbers.

Can you give me an example of a for loop?

Sure! Here's a simple example in Python:

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

This will print numbers 0 to 4.

What if I need to loop through a list instead?

You can do that too! For example:

my_list = [10, 20, 30]
for item in my_list:
    print(item)

This will print each item in the list.

Are there any situations where I shouldn't use a for loop?

Yes, if you don't know the number of iterations in advance, a while loop might be more appropriate.
