Here is my code so far - I am simply trying to say that if the input isnt one of these words, to redo the loop. However, although 'monday' works, the other days dont.
run_day = input("On which day do you want your code to run? ")
while run_day.lower() != ("monday" or "tuesday" or "wednesday" or "thursday" or "friday" or "saturday" or "sunday"):
run_day = input("On which day do you want your code to run? ")
