Python Int对​​象不可调用

Question

请帮忙！我不明白这里的错误。为什么当我输入0,1或2以外的数字时，出现错误：“'int'object is not callable”？相反，假设打印出“您输入的数字不正确，请重试”，然后回到提问。

第二个问题：我该如何更改代码，即使我输入字母字符，它也不会给我Value Error并继续重新提问？谢谢！

def player_action():   
    player_action = int(input("Enter 0 to stay, 1 to go Up, or 2 to go Down: ")) 

    if player_action == 0: 
     print ("Thank You, you chose to stay") 


    if player_action == 1: 
     print ("Thank You, you chose to go up") 

    if player_action == 2: 
     print ("Thank You, you chose to go down") 

    else: 
     print ("You have entered an incorrect number, please try again") 
     player_action() 

player_action() 

Answer 1

你应该改变变量名@Pedro洛比托建议，使用while环路@Craig建议，并且还可以包括try...except语句，但不的方式@ polarisfox64做到了，因为他已经把它在错误的位置。

这里是供您参考的完整版本：

def player_action():  
    while True: 
     try: 
      user_input = int(input("Enter 0 to stay, 1 to go Up, or 2 to go Down: ")) 
     except ValueError: 
      print('not a number') 
      continue 

     if user_input == 0: 
      print ("Thank You, you chose to stay")   

     if user_input == 1: 
      print ("Thank You, you chose to go up") 

     if user_input == 2: 
      print ("Thank You, you chose to go down") 

     else: 
      print ("You have entered an incorrect number, please try again") 
      continue 
     break 

player_action() 

Answer 2

只要改变变量名player_action到功能的差异名称，即：

def player_action(): 
    user_input = int(input("Enter 0 to stay, 1 to go Up, or 2 to go Down: ")) 
    if user_input == 0: 
     print ("Thank You, you chose to stay") 
    elif user_input == 1: 
     print ("Thank You, you chose to go up") 
    elif user_input == 2: 
     print ("Thank You, you chose to go down") 
    else: 
     print ("You have entered an incorrect number, please try again") 
     player_action() 

player_action()

首先回答你的问题已经被佩德罗回答，但作为第二个答案，一尝试不同的说法应该解决这个问题：

编辑：噢，抱歉，我搞砸了一点点......有更好的答案，但我想我应该花时间来解决这个问题

def player_action(): 
    try: 
     player_action_input = int(input("Enter 0 to stay, 1 to go Up, or 2 to go Down: ")) 
    except ValueError: 
     print("Non valid value") # or somehting akin 
     player_action() 
    if player_action_input == 0: 
     print ("Thank You, you chose to stay") 
    elif player_action_input == 1: 
     print ("Thank You, you chose to go up") 
    elif player_action_input == 2: 
     print ("Thank You, you chose to go down") 
    else: 
     print ("You have entered an incorrect number, please try again") 
      player_action() 

player_action()
