Question

For example, I have a function:

def foo(a, b, c):
    pass

Now I have a dict:
d = {'a': 1, 'b': 2, 'c': 3}
I have to write something like:
foo(d['a'], d['b'], d['c'])
I’d like to know, could I just pass a collection of the arguments(like d) to the function?

Sure, you can pass a dict as kwargs:

def foo(a, b, c):
    print a, b, c

d = {'a': 1, 'b': 2, 'c': 3}
foo(**d)

Output:

1 2 3
