Python Function Parameter As A Global Variable

I have written the following function, it takes in a variable input_name. The user then inputs some value which is assigned to input_name. I want to know the best way to make input

Solution 1:

The simplest thing would be to return the value, and assign it outside the function:

defmy_input(prompt):
    #.. blah blah..return the_value

month = my_input("Please enter the month")
# etc.

Solution 2:

Other people are saying something like this:

definput(prompt):
    return value

value = input(param1,param2, ...)

And that's what you really want to be doing, but just so you know, you can use globals() for changing global variables:

definput(input_name, prompt):
    globals()[input_name] = value

Solution 3:

What you want to do is probably a bad practice. Just return input_name from the input function.

definput(param1,param2):
   return value

value = input(param1,param2, ...)
