Using user input to reference function in another file in python

Question

In a text adventure game (python), I get user input for the next action and use regex to parse the input into two variables. The two variables are the verb and noun of the command, still in string form. For example, user input leads to...

final_noun = 'blow' final_verb = 'bubbles'

The regex is working correctly.

In another file, called actions, I have a list of functions for verbs/actions, including the blow function. I want to call this function up by purely using the final_noun and final_verb from regex. Also, I have the actual final verb object bubbles in the file GameFiles.

i tried: actions.final_verb(Gamefiles.final_noun)

which doesnt work because the inputs are still a string. i then tried using eval in many different ways, such as: actions.eval(final_verb(GameFiles.eval(remaining_noun)))

(This also didn't work)

Thank you for your time

final_noun = 'blow' final_verb = 'bubbles' Aren't those reversed? — John Gordon

@johnGordon yes you are correct, good catch, i mistakenly reversed those, but only when i posted this question, not in my original code. — Go West Winner

I think you can do it by writing:

eval('actions.' + final_verb)(eval('GameFiles.' + remaining_noun))

given actions and Gamefiles are imported, which means you are able to run:

actions.blow(Gamefiles.bubbles)

However you should reconsider keeping your functions and data stored that way. A simple and a little bit better way to do this would be creating a dictionary with all your functions and objects and then accessing them through get_item:

verbs = {'blow' : actions.blow}
nouns = {'bubbles' : Gamefiles.bubbles}

verbs[final_verb](nouns[final_noun])
