[python] Python - use list as function parameters

How can I use a Python list (e.g. params = ['a',3.4,None]) as parameters to a function, e.g.:

def some_func(a_char,a_float,a_something):
   # do stuff

This question is related to python list function-parameter

The answer is


Use an asterisk:

some_func(*params)

You want the argument unpacking operator *.


This has already been answered perfectly, but since I just came to this page and did not understand immediately I am just going to add a simple but complete example.

def some_func(a_char, a_float, a_something):
    print a_char

params = ['a', 3.4, None]
some_func(*params)

>> a
