Correct an "impure" function
While helping your coworker with their data processing task, you couldn't help but notice that some of the functions they have written are actually not pure functions. Oops! It seems like maybe they almost grasped the concept, but not quite yet. Now you're going to have to help them by making a couple of corrections to what they've written.

# Pass in all needed variables as parameters
def scale_list(input_list):
new_list = []
for item in input_list:
# Don't rely on variables that aren't passed in as parameters
new_item = (item - mean_shift) / scaling_value
new_list.append(new_item)
return new_list
