Feed python function with a variable number of arguments

Question

I have a script that reads a variable number of fields from an input file and pass them to a function as arguments. For example:

file 1 with fields: A,B a

Answer 1

you should use args and kwargs like this:

def foo(*args, **kwargs):
  pass

in this way you can get positional and named parameters, args should be a list of values, holding the positional arguments, kwargs should be a dictionary, its keys the argument name with its value
