title: understanding python global objects across modules
introduction:
in python, global objects play a crucial role in sharing data across different modules within a program. this tutorial will guide you through the concept of global objects, their scope, and how to use them effectively across modules.
in python, a global object refers to a variable declared outside of any function or class, making it accessible throughout the entire program. these global objects provide a means to share data across different parts of your code, including multiple modules.
global objects have a global scope, meaning they can be accessed from any part of the program. however, it is essential to understand the scope and lifetime of these objects to use them effectively.
to create a global object, simply declare a variable outside of any function or class. for example:
to access global objects in other modules, you need to import the module where the global object is defined. here's an example:
let's consider an example where a configuration parameter is shared across multiple modules:
understanding python global objects and their usage across modules is essential for building modular and maintainable code. by following the best practices outlined in this tutorial, you can effectively share data across different parts of your program while maintaining code clarity and organization.
