How to pass an integer as a key in python?

I have written the following code, that works fine when I pass a character or a string as a key.

def myfunc(**num):
    for i in num:
        print(i, num[i])

myfunc(a="One", b="Two")

However, when I try to pass integers instead of a or b, for example:

myfunc(1="One", 2="Two")

I get the following message:

SyntaxError: expression cannot contain assignment, perhaps you meant "=="?

Is there anything I could do about this?

>Solution :

This is not possible, as all keyword arguments are syntactically required to be strings. The error message your example gets is cryptic, but you can easily demonstrate this by passing a dictionary with integer keys as the keyword arguments:

def myfunc(**num):
    for i in num:
        print(i, num[i])


myfunc(**{1: 'one', 2: 'two'})
# TypeError: keywords must be strings

If you must use integer keys, just pass a dictionary as an argument instead and avoid all the problems:

def myfunc(num):
    for i in num:
        print(i, num[i])


myfunc({1: 'one', 2: 'two'})
