Genuinely hard to tell if satire.

Just in case not, consider whether the short function

   def is_even(x):
      return (x%2) == 0

Handles a wider range of input conditions than the higher LOC function

   def is_even(x):
     if x == 0:
       return True
     if x == 2:
       return True
     if x == 4:
       return True
     ...
     return False
