第18課，代碼

-----------------------------------------------------------------------------------------------------------------------

# 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 takes no arguments

def print_none():

print "I got nothin'. "

print_two("Zed","Shaw")

print_two_again("Zed", "Shaw")

print_one("First!")

print_none()

逐條回溯，發(fā)現(xiàn)標(biāo)紅處的%遺漏。

重新運(yùn)行，正常。
