Tell us what’s happening:
This is about last Friday’s challenge — Wider aspect ratio. (Python)
While it is probably not the most elegant, I wrote it without importing any library, my code returns the correct responses and in the requested format. But the testing is failing 
Your code so far
def get_wider_aspect_ratio(a, b):
wider = []
# extract numbers from text into list
a_list = a.split('x')
b_list = b.split('x')
# determine the wider ratio
if (int(a_list[0]) / int(a_list[1])) > (int(b_list[0]) / int(b_list[1])):
wider = [int(a_list[0]), int(a_list[1])]
else:
wider = [int(b_list[0]), int(b_list[1])]
# reduce to lowest ratio numbers
red_wider = reducer(wider)
# return as text
return f'"{red_wider[0]}:{red_wider[1]}" '
def reducer(dim):
result = 0
larger_a = True if dim[0] > dim[1] else False
if larger_a:
first = dim[0]
second = dim[1]
check = dim[1]
else:
first = dim[1]
second = dim[0]
check = dim[0]
while check >= 0:
if check == 0:
return None
if first % check == 0 and second % check == 0:
if larger_a:
return [first // check, second // check]
else:
return [second // check, first // check]
else:
check -= 1
