Replace while with for

Sourcery refactoring id: while-to-for

Description:

Replaces a while loop with a counter by a for loop

Before:

i = 0
while i < 10:
    print("I love hats")
    i += 1

After:

for i in range(10):
    print("I love hats")

Explanation:

We often need to iterate over the same bit of code a certain number of times. Developers who are unfamiliar with Python may consider using a while loop for this, but it's almost certainly better to use for.

Converting from while to for means the explicit handling of the counter can be removed, shortening the code and making it esier to read.
