Answer 1

除了错误的缩进之外，在条件语句中，您需要将赋值运算符替换为比较运算符。此外， a:中缺少 a if statement。

def register():
    print("Register")
    login = input("Enter login")
    passwd = input("Enter password")
    passwdacc = input("Accept password")

    if passwdacc == passwd:
        print("You have registered, now please sign up")
    else:
        print("Try again, passwords don't match")

    login2 = input("Enter login")
    password = input("Enter password")

    if password == passwd and login2 == login:
        print("Accepted")
    else:
        print("Try again")

Answer 2

    def register():
        print("Register")
        login = input("Enter login")
        passwd = input("Enter password")
        passwdacc = input("Accept password")
        if passwdacc = passwd:
            print("You have registered, now please sign up")
        else:
            print("Try again, passwords dont matches")
        login2 = input("Enter login")
        password = input("Enter password")
        if password = passwd and login2 = login
            print("Accepted")
        else:
            print("Try again")
