How to expand a list to function arguments in Python [duplicate]

Question

It exists, but it's hard to search for. I think most people call it the "splat" operator.

It's in the documentation as "Unpacking argument lists".

You'd use it like this: foo(*values). There's also one for dictionaries:

d = {'a': 1, 'b': 2}
def foo(a, b):
    pass
foo(**d)

You should use the * operator, like foo(*values) Read the Python doc unpackaging argument lists.

Also, do read this: http://www.saltycrane.com/blog/2008/01/how-to-use-args-and-kwargs-in-python/

def foo(x,y,z):
   return "%d, %d, %d" % (x,y,z)

values = [1,2,3]

# the solution.
foo(*values)

Try the following:

foo(*values)

This can be found in the Python docs as Unpacking Argument Lists.

That can be done with:

foo(*values)
