How to use *args and **kwargsΒΆ
*args and **kwargs are 2 useful python mechanisms to define and call methods or functions with a variable number of arguments.
*args is a list :
def test_var_args(*args):
for arg in args:
print("arg:", arg)
test_var_arg(172, "3", "foo", [1,2,3])
**kwargs is a dictionary-like structure :
def test_var_kwargs(**kwargs):
for key in kwargs:
print("arg: %s = %s" % (key, kwargs[key]))
test_var_kwargs(key1=3, key2="foo", foo=[1,2])
