Global Variables Across Python Modules/Files By default, the global variables are accessible across multiple functions of the samemodule. Now, we’ll see how to share global variables across the modules. First, create a special moduleconfig.pyand create global variables in it. Now, import the c...
In this tutorial, you'll learn how to use global variables in Python functions using the global keyword or the built-in globals() function. You'll also learn a few strategies to avoid relying on global variables because they can lead to code that's diffi
Global Variables Variables that are created outside of a function (as in all of the examples in the previous pages) are known as global variables. Global variables can be used by everyone, both inside of functions and outside. ExampleGet your own Python Server...

使用globals()并不是一个很好的例子。 而且,它是通过“配置”(后者是普通的python脚本)导入的,而不是相反的方式。 我在一些我从事过的项目上使用了“声明性python”,并且在为这些项目编写配置时曾使用globals()。 您当然可以辩解说,这是由于配置“语言”的设计方式存在缺陷。 以这种方式使用globals()不会产生非常...
PythonBasics Scope is defined as an area where eligible variables can be accessed. To enforce security, programming languages provide means by which a user can explicitly define these scopes. It is important to understand the use of scopes and how to deal with them. In this article, we will...
