在Python字典中将变量作为值

Question

I have 4 private variables:

__first = 0
__second = 0
__third = 0
__fourth = 0

I added them to a dictionary like this:

numbers = {one: __first, two: __second, three: __third, fourth: __fourth)

When I do __first += 1 , the value in the dictionary won't get changed while the original variable would.

Any help?

Please check if this works for you. I Simply Updated the value based on the key. and you get a refresh dictionary. You may be asking youself why If I update the variable they wont update in the dictionary? they will do the first time, but the second time they wont since they are allocated in other block of memory that can only be accesed via index location [x] position. So if you need to update it you may need to update the values based on their key in this case.

__first = 0
__second = 0
__third = 0
__fourth = 0

dict = {"first": __first,
        "second": __second,
        "third": __third,
        "fourth": __fourth}


def updateDict(dict, new_key, new_value):

    for key, value in dict.items():
        if key == new_key:
            dict[key] = new_value

    print(dict)

    return dict


dict = updateDict(dict, "first", 1)
# {'first': 1, 'second': 0, 'third': 0, 'fourth': 0}

dict = updateDict(dict, "second", 10)
# {'first': 1, 'second': 10, 'third': 0, 'fourth': 0}
