使用字典从字符串调用函数

Question

I would like the first two words of a user input string to be read as function arguments for where to save the string. I've settled on using a dict instead of many if statements, but I'm not sure how to structure the dict.

I believe this is a correct start:

input: "question physics What happens to atoms when they are hit by photons?" result: program saves the input in location questions\\physics

raw_entry = input("Enter text in the following format: type subtype text")
instructions = raw_entry.split()[:2]

The two words (each being a "get_id" in the example) will designate where to save the text. This example seems to be what I'm looking for, but I'm not sure how to change it for my case.

function_dict = {'get_id': 
                        (
                        # function
                        requests.get,

                        # tuple of arguments
                        (url + "/users/" + user,), 

                        # dict of keyword args
                        {'headers': self.headers}
                        )
                 }

Let me know if I'm going about this logically or if it doesn't make sense. Thanks!

You will need to define the functions separately from the dictionary

For example:

def get_id():
    ... the function's code ...

function_dict = { "get_id":get_id, ... }

you can then call the function with its keyword:

function_dict["get_id"]()

but you can also do this without a dictionary if the keyword is the same as the function name:

globals()["get_id"]()
