05:47Of course, you don’t have to do this in Python because Python allows you toreturn multiple values.So you can, in a single return statement,return the personalized greetingand the incremented value of how many times the function has been calledpacked in a tuple. ...
As the last item on the agenda for tuples, I want to show you a place where you may have used tuples implicitly without knowing about it. And that is how you can return multiple values from a function, which isn’t quite the right way to say this…

Item 19: Never Unpack More Than Three Variables When Functions Return Multiple Values Unpacking into four or more variables is error prone and should be avoided; instead, return a small class or namedtuple instance. Item 22: Reduce Visual Noise with Variable Positional Arguments ...
函数和过程的联系:每个Python函数都有一个返回值,默认为None,也可以使用“return value”明确定定义返回值 python提供了很多内置函数 二、创建函数 1、语法 def functionName(parameter1,parameter2): suite 2、一些相关的概念 def是一个可执行语句 因此可以出现在任何能够使用语句的地方,甚至可以嵌套于其它语句中...
Help on function square in module __main__: square(x) Calculate the square of the number 并非真正函数的函数 数学意义上的函数,总在计算其参数后返回点什么。python有些函数却并不返回任何东西。 python的函数就是函数,即便它从学术上讲并不是函数。没有return语句,或者虽然有return语句,但是return后边乜有...

首先,我们导入print_function和argparse模块。通过从__future__库导入print_function,我们可以像在 Python 3.X 中编写打印语句一样编写它们,但仍然在 Python 2.X 中运行它们。这使我们能够使配方与 Python 2.X 和 3.X 兼容。在可能的情况下,我们在本书中的大多数配方中都这样做。
