Python 为什么编撰人会说；无效语法"；我的第一行计算？

我必须使用循环和简单的代码，我不能使用函数。我在第一行计算中出错，我不知道为什么

  import random

  #Input
  winning_number = random.randint(10,100)
  guessed_number = int(input('Enter your lottery pick (2 digits) or -999 to quit:')

  #Calculations
  first_winning_number = winning_number // 10
  second_winning_number = winning_number % 10
  first_guessed_number = guessed_number // 10
  second_guessed_number = guessed_number % 10

  #If Statements
  while guessed_number != -999:
      if guessed_number == winning_number:
          print('Exact Match: You win $10,000')
      if first_guessed_number == second_winning_number and second_guessed_number == first_winning_number:
          print('Match all digits: You win $3,000')
      if first_guessed_digit == second_winning_digit:
          print('Match one digit: You win $1,000')
      if first_guessed_digit == first_winning_digit:
          print('Match one digit: You win $1,000')
      if second_guessed_digit == second_winning_digit:
          print('Match one digit: You win $1,000')
      if second_guessed_digit == first_winning_digit:
          print('Match one digit: You win $1,000')
      else:
          print(guessed_number)

第三行中缺少第二个括号

其

guessed_number=int（输入（'输入您的彩票选择（2位数）或-999退出：'））

不是

---

guessed_number=int（输入（'输入您的彩票选择（2位数）或-999退出：'）

如果您的编译器不符合您的语法，则不应将其称为编译器：-根据一般经验法则，如果您遇到这样的神秘错误，请查看包含代码的前一行。它通常缺少

）

。这很容易发生，许多IDE都会吞下额外的收尾参数。
