本文通过几个简单的Python函数示例介绍了如何使用不同类型的参数，包括普通参数、*args和**kwargs等，并解释了它们的区别和应用场景。

# this one is like your scripts with argv
def print_two(*args):
arg1, arg2 = args print "arg1: %r, arg2: %r" % (arg1, arg2)
# ok, that *args is actually pointless, we can just do this
def print_two_again(arg1, arg2):
print "arg1: %r, arg2: %r" % (arg1, arg2)
# this just takes one argument
def print_one(arg1):
print "arg1: %r" % arg1
# this one takes no arguments
def print_none():
print "I got nothin'."
print_two("Zed","Shaw")
print_two_again("Zed","Shaw")
print_one("First!")
print_none()
