How Python uses *arg and **kwargs__python

This particular definition of *arg and *kwargs in a function is used to pass an indefinite number of arguments to a function. *arg (Only one *) is used to pass the list array, while **kwargs (two *) is used to pass the Dict dictionary

def Test_var_args (Farg, *args):
    print "formal arg:", Farg for
    arg in args:
        print "Another arg:", arg

test _var_args (1, "two", 3)

# Results:
formal arg:1
another arg:two another arg:3

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)

# Results:
formal arg:1
another keyword arg:myarg2:two another keyword

use *arg and **kwargs when calling functions

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)

# Results:
arg1:1
arg2:two
arg3:3

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)

# Results:
arg1:1
arg2:two
arg3:3
