Python: How to use *args and **kwargs #python #args #kwargs #c0ldlimit

gistfile1.py

# This example passes one formal (positional) argument, and two more variable length arguments.
def test_var_args(farg, *args):
    print "formal arg:", farg
    for arg in args:
        print "another arg:", arg

test_var_args(1, "two", 3)

# Here is an example of how to use the keyworded form. Again, one formal argument and two keyworded variable arguments are passed.
def test_var_kwargs(farg, **kwargs):
    print "formal arg:", farg
    for key in kwargs:
        print "another keyword arg: %s: %s" % (key, kwargs[key])

test_var_kwargs(farg=1, myarg2="two", myarg3=3)

# This special syntax can be used, not only in function definitions, but also when calling a function. 
def test_var_args_call(arg1, arg2, arg3):
    print "arg1:", arg1
    print "arg2:", arg2
    print "arg3:", arg3

args = ("two", 3)
test_var_args_call(1, *args)

# Here is an example using the keyworded form when calling a function:
def test_var_args_call(arg1, arg2, arg3):
    print "arg1:", arg1
    print "arg2:", arg2
    print "arg3:", arg3

kwargs = {"arg3": 3, "arg2": "two"}
test_var_args_call(1, **kwargs)
