Example to Create Python Modules Here is an example where we create two modules:mycheck.pyandmymath.py. These modules contain functions for number checking and mathematical operations. Module 1: mycheck.py defiseven(n):ans=Falseifn%2==0:ans=Truereturnansdefisodd(n):ans=Falseifn%2==1:an...

For example, to install NumPy: Run the following command: Pip install numpy Add the site packages to the Python path as follows: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\GE Digital\iHistorian\CollectorServiceExtensions\PythonExpressions\PythonPath After you do so, the changes are reflected ...
Packages are a way of structuring Python’s module namespace by using “dotted module names”. For example, the module nameA.Bdesignates a submodule namedBin a package namedA. Just like the use of modules saves the authors of different modules from having to worry about each other’s global...

这将调用Modules/gcmodule.c文件中的collect(),该文件包含垃圾收集器算法的实现。 结论 在第1 部分中,我们介绍了源代码库的结构,如何从源代码编译以及 Python 语言规范。当你深入了解 Python 解释器过程时,这些核心概念在第 2 部分中将是至关重要的。
6.1.1. Executing modules as scripts When you run a Python module with 当你这样运行Python模块: python fibo.py <arguments> the code in the module will be executed, just as if you imported it, but with the__name__set to"__main__". That means that by adding this code at the end of...

So far, we’ve seen how to type code interactively and run files of code created with a text editor (modules). If you’re going to use Python on a Unix, Linux, orUnix-like system, you can also turn files of Python code into executable programs, much as you would for programs coded...
