This is a code i am working on but when i execute it , creates a problem towards the end
restart = "No" or "no"
while restart == "No" or "no":
    print("League Registration")
    Fristname = input("What is first name?")
    Lastname = input("What is your Last name?")
    Nickname = input("What is your nick name?")
    Eaddress = input("What is your e-mail address?")
    Skill = input("What is your skill level, E for expert or C for casual?")
    if Skill  == "C" or Skill == "c":
        print("Casual")
    elif Skill == "E" or Skill == "e":
        print("Expert")
    print (" These are your personal details:")
    print ("First Name:",Fristname)
    print("Last Name:",Lastname)
    print("Nickname:",Nickname)
    print("Email Address:",Eaddress)
    print("Skill Level:",Skill)
    Detailscon = input("Are your personal details correct: Yes or No?")
    if restart == "Yes" or "yes":
        print("Thanl you , you are now registered")
    elif restart == "No" or "no":
        print("Try again")
my code towards the end keeps messing up i don't know what to do
