# OK, we have some work to do
# let's try to swap elements:
if [data[1], data[0]] == [5, 5]:
return 10 # Goodbye!
# Huh! That wasn't the Pythonic way to swap, let's do it like this:
if data[::-1] == [5, 5]:
return 10 # Goodbye forever!
# Alas! I need another way to swap.
# Aha! Lists have some convenient methods I never used before:
data.reverse()
if data == [5, 5]:
return 10
# Oh, no! Here again!
# I have to ask someone
# 2 hours later:
# They told me I should use '+'
if [data[1]] + [data[0]] == [5, 5]:
return 10
# No wonder, my code was better... But they insisted!
# I'm exhausted, next morning I'll try lambda-s and list comprehensions...
# AFK
# Hi! I'm Alice, the wife of this idiot
return sum(data)
# Good morning! How are you?
# What was that?
# Solved. If only I could find the right way to swap...
