Pass a list to a function to act as multiple arguments
Yes, you can use the *args
(splat) syntax:
function_that_needs_strings(*my_list)
where my_list
can be any iterable; Python will loop over the given object and use each element as a separate argument to the function.
See the call expression documentation.
There is a keyword-parameter equivalent as well, using two stars:
kwargs = {'foo': 'bar', 'spam': 'ham'}
f(**kwargs)
and there is equivalent syntax for specifying catch-all arguments in a function signature:
def func(*args, **kw):
# args now holds positional arguments, kw keyword arguments
Since Python 3.5 you can unpack unlimited amount of list
s.
PEP 448 - Additional Unpacking Generalizations
So this will work:
a = ['1', '2', '3', '4']
b = ['5', '6']
function_that_needs_strings(*a, *b)
function_that_needs_strings(*my_list) # works!
