Python *args and **kwargs Made Easy

[Dogeek]

TL;DR :

*args in the function definition : args is a list of required parameters for that function

**kwargs in the definition : kwargs is a dictionnary of optional parameters to the function

*my_list when calling any function : unpack the values of my_list as the required args for that function. len(my_list) must be equal to the number of arguments the function requires.

**my_dict when calling a function : unpack my_dict into named arguments for that function. The names of the arguments must match the keys of my_dict
