我正在尝试在我的 class 中创建一个用户输入字典以获得额外的信用，但我无法弄清楚如何正确结束程序

Question

my_dict = dict()
more = True
while more:
  bad_input = True

  while bad_input:
    user_input = input("Enter key and value seperated buy commas(,):")
    result = user_input.find(',') 
    print ("Substring ',' found at index:", result )

    if result != -1 and user_input != 'quit':
      bad_input = False
      key , value = user_input.split(",")
      key = key.strip()
      value = value.strip()
      my_dict[key] = value
      print (my_dict)
  if user_input == 'quit':
    print(my_dict)
    break

This is my code and I need it to find the ',' in the user input dictionary and also when you type 'quit' the program needs to end. My teacher is not educated in python enough to help me, please help!

Answer 1

break only breaks the inner loop. In order to break out of the nested while loops without changing too much of your logic you will need to change the values that they check.

In this case, setting both bad_input and more to False will suffice:

if user_input == 'quit':
    print(my_dict)
    more = False
    bad_input = False

With that said, you don't even need both loops. Use a single while then you will be able to use break :

my_dict = dict()
while True:
    user_input = input("Enter key and value separated buy commas(,):")
    result = user_input.find(',')
    print("Substring ',' found at index:", result )

    if result != -1 and user_input != 'quit':
        bad_input = False
        key , value = user_input.split(",")
        key = key.strip()
        value = value.strip()
        my_dict[key] = value
        print (my_dict)
    if user_input == 'quit':
        print(my_dict)
        break
