Just tried something really simple: def is_palindrome

Copilot suggestion was

  def is_palindrome(word):
      if word == word[::-1]:
          return True
      else:
          return False

So good for technically correct solution but still...

This is an anti-pattern I think in pretty much any language that I know of and something that about half of my beginning students try when they learn about branching..

UPDATE: more howlers along the same vein

  def haystack_contains_needle(haystack, needle):
      if needle in haystack:
          return True
      else:
          return False
