错误代码：（编译时一直报错）IndentationError:expected an indented block：说明此处需要缩进# 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 nothing'."print_two("Zed","Shaw")
print_two_again("Zed","Shaw")
print_one("First!")
print_none()改正后的代码：（加上了空格）
# this one is like your scripts with argv
def print_two(*args): #Python 创建一个函数，我们使用到的命令是 def ，也就是“定义(define)”的意思。arg1, arg2 = args #冒号以下，使用 4 个空格缩进的行都是属于 print_two 这个函数的内容。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 nothing'."print_two("Zed","Shaw")
print_two_again("Zed","Shaw")
print_one("First!")
print_none()这篇关于《笨办法学Python》习题18：命名，变量，代码，函数的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
