company.py: create acompany.pyfile to import global variables and modify them. In thecompany.pyfile, we import the config.py module and modify the values of the name and address. # load config moduleimportconfig# modify global variablesconfig.company_name ='ABC Tech'config.address ="New Str...
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 ...
A global variable in Python is a variable defined at the module level, accessible throughout the program. Accessing and modifying global variables inside Python functions can be achieved using the global keyword or the globals() function. Python handles name conflicts by searching scopes from local...

The global variable x is defined in module1.py and modified in module2.py using the global keyword. The change is reflected across both modules. Best Practices for Using the Global KeywordAvoid Overuse: Overusing global variables can make code harder to understand and maintain. Use Function ...
我无法理解何时需要 global_variables_initializer() 。在上面的代码中,如果我们取消注释第 4 行和第 7 行,我可以执行代码并查看值。如果我按原样运行,我会看到崩溃。
