Python - use list as function parameters
195,599
Solution 1
You can do this using the splat operator:
some_func(*params)
This causes the function to receive each list item as a separate parameter. There's a description here: http://docs.python.org/tutorial/controlflow.html#unpacking-argument-lists
Solution 2
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
Solution 3
Use an asterisk:
some_func(*params)
Solution 4
You want the argument unpacking operator *.

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
