Just a small note that the walrus operator gives you some wiggle room here:

  add_5_to_square_if_greater_than_10 = lambda x: squared + 5 if (squared := x * x) > 10 else x
  assert add_5_to_square_if_greater_than_10(2) == 2
  assert add_5_to_square_if_greater_than_10(5) == 30

yeah my bad. Not fully up to date with all the newer python 3 tricks. That walrus operator is a trap though imo.
