AI()

It throws UnboundLocalError: local variable 'name' referenced before assignment. How can I update name after asking it from the user?

Answer 1

name = "Aayan"

def AI():
    global name
    print("Hi, {}. I hope you are doing well :)".format(name))
    ask = input("How can i help you, {} ? : ".format(name))
    if ask == "change name" or "rename":
        new_name = input("What should I call you ? : ")
        name = new_name
        return name
    else:
        exit()


print(AI())

use global keyword inside function and call name
