Question

我正在为一个项目的系统工作，该系统询问用户是否要创建帐户或登录。我在第5行的'if'条件有问题。整个错误消息是：

Traceback (most recent call last):
  File "main.py", line 5, in <module>
    if login_or_signup("signup"):
TypeError: 'str' object is not callable

代码：

import uuid
import hashlib
login_or_signup = input("would you like to log in? Or signup?: ")

if login_or_signup("signup"):
  def hash_password(password):
      # uuid is used to generate a random number
      salt = uuid.uuid4().hex
      return hashlib.sha256(salt.encode() + password.encode()).hexdigest() + ':' + salt

  def check_password(hashed_password, user_password):
      password, salt = hashed_password.split(':')
      return password == hashlib.sha256(salt.encode() + user_password.encode()).hexdigest()

  new_pass = input('Please enter a password: ')
  hashed_password = hash_password(new_pass)
  old_pass = input('Now please enter the password again to check: ')
  if check_password(hashed_password, old_pass):
      print('The passwords match!')
  else:
      print('I am sorry but the password does not match')

else:
  print("(NOT CODED YET)")

这是一个小错误，正如其他人提到的那样。需要一个if语句内比较以下列方式字符串：

if login_or_signup == "signup":

如何解决：（类型错误：“海峡”对象不是可调用）
