How could I make checking user input case-insensitive?

I am adding a few ways of checking user input to my code. Instead of writing if Answer == ("Yes") or Answer == ("yes"), is there any way I could make the variable input case-insensitive, so that I don’t have to type the word yes twice? Additionally, would there be any way I could make the every variable input option in the line case-insensitive? if Answer == ("Yes") or Answer == ("yes") or Answer == ("Y") or Answer == ("y"):.

def Repeat():
  Answer = input ("\nDo you want to play again? (Y/N): ")
  if Answer == ("Yes") or Answer == ("yes") or Answer == ("Y") or Answer == ("y"):
    Game()
  if Answer == ("No") or Answer == ("no") or Answer == ("N") or Answer == ("n"):
    exit()
  if Answer == "Options" or Answer == "options" or Answer == "o" or Answer == "O":
    More()
  else:
    print ("Invalid Input")
    Repeat()

>Solution :

You can change the case of the user input and just check against that:

 answer = input("\nDo you want to play again? (Y/N): ").lower()
 if answer in ("yes", "y"):
     ...
