Take a parameter and run a function based on that parameter

What is a move efficient way to run a function dependant on a parameter. I will always know what x will be so I could store all these possibilities in a list but then how would this help me call the appropriate function?

Just for context, I have just over 12 possibility's for x and I get the feeling writing 12 if statements is just wrong.

def run(x):
    if x == "dog":
        dogfunction()
    if x == "cat":
        catfunction()

You could do:

def run(x):
    functions = {
        "dog": dogfunction,
        "cat": catfunction,
    }
    functions[x]()

This explicitly maps a string to a function. It also raises a KeyError in case the string isn't in the dictionary of functions.
