namespace python example

In Python, a namespace is a container that holds a collection of names, allowing you to organize your code and avoid naming conflicts. Namespaces help in avoiding naming collisions by providing a way to differentiate between variables, functions, classes, and other objects. Python has several types of namespaces, including the global namespace, local namespace, and built-in namespace.
The global namespace includes names defined at the top level of a module or script. Any variable, function, or class defined in this scope is part of the global namespace.
In this example, global_variable, global_function, and GlobalClass are part of the global namespace.
A local namespace is created when a function is called, and it includes parameters, local variables, and any nested functions.
Here, x, y, local_variable, nested_function, and nested_variable are part of the local namespace of the local_function.
The built-in namespace contains Python's built-in functions and types, such as print(), len(), int(), etc. These names are always available without the need for an explicit import.
In this case, len is part of the built-in namespace, and you can use it directly without importing.
You can access the contents of a namespace using the dot (.) notation. For example:
Here, we access the global namespace of the global_namespace_example module using the dot notation.
Understanding and managing namespaces is essential for writing clean and organized code. It helps prevent naming conflicts and makes your code more modular. Whether you are working with global, local, or built-in namespaces, understanding how they function will contribute to writing more efficient and maintainable Python code.
