To execute a block of code a specific number of times.

The for...in range() loop.
Why are loops important in programming?
They allow us to automate repetitive tasks and write more efficient code.
Explain the concept of a loop counter.
A variable that keeps track of the number of times a loop has executed.
What is the range() function in Python?
