How to pass dynamic generated arguments to function?

I have the function:

def do_something(arguments_list):
    user = User(name = argument_list['name'],
                age = argument_list['age'],
                ...
                sex = argument_list['sex'])

The argument_list (dictionary) don't always have the same keys. For example, sometimes it looks like this:

arguments_list = {'name': 'Zara', 'age': 7, 'sex': 'Male'}

but it also could be:

arguments_list = {'name': 'Zara'}

How can I dynamically pass arguments to the function (in this case constructor of User class) depends on what keys are in the dictionary?

This would take any number of keyword arguments and pass them to User:

def do_something(**kwargs):
    user = User(**kwargs)

If you know more about the arguments you could also do something like this (in this case you most likely want the do_something default values to be the same as the User default values):

def do_something(name=None, age=None, sex=None):
    user = User(name=name, age=age, sex=sex)

Let me know if something needs clarification.

Here you have more information about *args and **kwargs: https://www.saltycrane.com/blog/2008/01/how-to-use-args-and-kwargs-in-python/

>>> def do_something(**arguments_list):
    name = arguments_list['name']


>>> do_something(name="name")
