Compare Two Lists

When you need to find a difference in large lists, simply compare their indexes one at a time and break when something doesn't match.

Usage

x = ['a', 'b', 'c']
y = ['a', 'c', 'c']

for i, z in enumerate(zip(x, y)):
  if z[0] != z[1]:
    print(f'{z} at index {i} doesn\'t match!')
    break
  else:
    print(f'Lists match at index {i}!')

Output will be:

Lists match at index 0!
('b', 'c') at index 1 doesn't match!
