爲什麼我在這段代碼中得到無效的語法錯誤，Python？

Question

代碼：

students = [] 
choice = None 
while choice != 0: 

     print(
    """ 
    0 - Exit 
    1 - Show all students 
    2 - Add a student 
    """ 
    ) 
     choice = input("Choice: ") 
     print() 
     if choice == "0": 
      print("Goodbye") 
      break 
     elif choice == "1": 
      print("\nStudents: ") 
      for entry in students: 
       email, name, number = entry 
       print(name, "\t", email, "\t", number) 
     elif choice == "2": 
      name = input("What is the students name?") 
      email = input("What is the students email adress? ") 
      number = int(input("What is the students number? ")  
      entry = email, name, number 
      students.append(info) 
      students.sort(reverse=False) 
      student = students 
     else: 
      print("Sorry, but", choice, "isn't a valid choice.") 

當我在編譯器中運行它，我得到一個語法錯誤行

entry = email, name, number 

我不知道爲什麼，請告訴我。

Answer 1

錯誤行的正上方有一條缺少的)。

number = int(input("What is the students number? ") #here 
entry = email, name, number 

一般而言，缺少括號會導致堆棧跟蹤指向緊隨其後的行。
