How do I use f-strings in loops in Python?

You can use f-strings in loops to format strings dynamically. For example:

for i in range(5):
    print(f'This is iteration number {i}')

Can you explain how that works?

Sure! The f before the string allows you to embed expressions inside curly braces. In the loop, i takes values from 0 to 4, and each iteration prints the current value of i.

What if I want to include multiple variables?

You can include multiple variables in an f-string like this:

name = 'Alice'
for i in range(3):
    print(f'{name} is on iteration {i}')

That makes sense! Are there any performance considerations?

F-strings are generally faster than other string formatting methods in Python, especially in loops, because they are evaluated at runtime.
