Reproduce a C function pointer array in Python

Question

I have a Python program asking the user for input like a shell, and if I detect some specific keywords I want to go inside some specific functions.

The thing is that I would like to avoid doing a lot of if and else if. Usually in C to avoid this situation I use a function pointer array that I travel with a while and use strcmp to check the input.

I would like to know how to do that in Python if it is even possible.

Are you looking for something like stackoverflow.com/q/60208/3001761? For those of us not au fait with C, it might be helpful to provide more information about what you're talking about. — jonrsharpe

Maybe you want a dictionary mapping string keys to functions? I don't understand why you would need to use a while loop in C. — Shashank

@Shashank you could use a while loop if the array of function pointers was NULL terminated. — Paul Rooney

Yes, a dictionary is what I need apparently, thank you! (and yes I use a NULL terminated array for my loop in C) — Roger

In Python you use a dictionary.

Example:

keyword2func = {
    "word1": function_word1,
    "word2": function_word2,
}

word = input("")
keyword2func[word]()
