Question

def _main_(userInput1):
   if userInput1 ==create:
      userName1=input('Please enter your username : ')
      password1=input('Please enter your password : ')                       
      createAccount(userName1, password1)
   else:
      userName2=input('Please enter your username : ')
      password2=input('Please enter your password : ')
      logIn(userName2,password2)
userInput1=input('Would you like to create a account or long in, type create or login ')

_main_(userInput1)

我一直收到错误：

'create'未定义

有人可以帮忙吗？

Answer 1

如果您要检查func applicationDidFinishLaunching(_ aNotification: Notification) { NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: #selector(updateClock), userInfo: nil, repeats: true) } func updateClock() { let date = NSDate() let calendar = NSCalendar.current let components = calendar.dateComponents([.second],from:date as Date) as NSDateComponents if components.second == 0 || components.second == 30 { makeStatusMenu() } } func makeStatusMenu() { }是否等于字符串userInput1，则需要将create放在引号中，如下所示：create或此{{1} }}。否则，Python会检查'create'是否等于变量 "create"。

Answer 2

您需要将userInput1更改为create，因为当您询问用户是否要创建用户时，输入默认为字符串，因此您需要引号以告知编译器识别它是一个字符串，而不是将if userInput1 == create视为变量。

Python - 来自用户的输入
