1.编程语言中的函数与数学意义的函数是截然不同的俩个概念,编程语言中的函数是通过一个函数名封装好一串用来完成某一特定功能的逻辑,数学定义的函数就是一个等式,等式在传入因变量值x不同会得到一个结果y,这一点与编程语言中类似(也是传入一个参数,得到一个返回值),不同的是数学意义的函数,传入值相同,得到的结...
All functions in the subprocess module are convenience wrappers around the Popen() constructor and its instance methods. Near the end of this tutorial, you’ll dive into the Popen class. Note: If you’re trying to decide whether you need subprocess or not, check out the section on deciding...

When your Python application uses a class in Tkinter, e.g., to create a widget, the tkinter module first assembles a Tcl/Tk command string. It passes that Tcl command string to an internal _tkinter binary module, which then calls the Tcl interpreter to evaluate it. The Tcl interpreter wi...
module的docstring:package目录下一般有多个.py文件,每个.py文件就是一个模块 .py文件的开头可以写docstring .py下包含多个classes或functions class or function的docstring 流程步骤 一般情况下,我们应该边开发边构建文档,开发过程中自己也经常会需要搜索已经实现的方法或类,因此“开发”和“构建文档”是同步进行的 首先...
