fix: Use the in keyword

[arnu515]

Using the in keyword is faster than having multiple equality statements.

Example:

test = input()

# Using ==
if test == "yes" or test == "y" or test == "oui":
  print("You agreed")
elif test == "no" or test == "n" or test == "non":
  print("You disagreed")

# Using in
if test in ["yes", "y", "oui"]:
  print("You agreed")
elif test in ["no", "n", "non"]:
  print("You disagreed")

See how much easier the second option is to read, correct and spot errors? Plus, it is faster to use in than comparing multiple times.

LMK if you need any changes :)
