I have a problem with this piece of code. Somehow if we put in 'register' or 'Register' as input, it goes to the register function, but after it prints the else: Aswell ("Bad input"); I have made more of these but cant find the fault in this one.

Please help me. Thanks! Here's my code:

def Boot(): 
        print "Type 'Login' + accountname to login."

        x = raw_input("> ")
        Name = x.split()

        if x == "Register" or x == "register":
            print "Registerbla"

        if Name[0] == "Login" or Name[0] == "login":
            print "Loginblabla"
        else:
            print "Bad input"

So what I see after input is: Registerbla Bad input

您缺少elseif 语句的部分。没有它，您实际上会检查两个单独的 if 语句：注册部分和登录/错误输入部分。相反，您应该使用elif：

    if x == "Register" or x == "register":
        print "Registerbla"
    elif Name[0] == "Login" or Name[0] == "login":
        print "Loginblabla"
    else:
        print "Bad input"

另外，考虑更改您的语句以检查小写，例如

if x.lower() == "register":
    # Now any capitalized variant of register will work!

当您输入register或Register

if Name[0] == "Login" or Name[0] == "login":

评估为假，打印Bad input
