What is the second type of loop in Python?

Python has two primary loop constructs: the for loop and the while loop. The for loop iterates over items of a sequence (list, tuple, string, etc.) and is considered the first type. The second type is the while loop, which repeatedly executes a block of code as long as a given condition remains true. Example:

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

The while loop is useful when the number of iterations is not known beforehand and depends on runtime conditions.
