Logoutin Python, a namespace is a system that assigns a unique name to each and every object. A variable or a method might be considered an object. Python has its own namespace, which is kept in the form of a Python dictionary. Let’s look at a directory-file system structure in a computer as an example. It should go without saying that a file with the same name might be found in numerous folders. However, by supplying the absolute path of the file, one may be routed to it if desired.
A namespace is essentially a technique for ensuring that all of the names in a programme are distinct and may be used interchangeably. You may already be aware that everything in Python is an object, including strings, lists, functions, and so on. Another notable thing is that Python uses dictionaries to implement namespaces. A name-to-object mapping exists, with the names serving as keys and the objects serving as values. The same name can be used by many namespaces, each mapping it to a distinct object. Here are a few namespace examples:
Local Namespace: This namespace stores the local names of functions. This namespace is created when a function is invoked and only lives till the function returns.
Global Namespace: Names from various imported modules that you are utilising in a project are stored in this namespace. It’s formed when the module is added to the project and lasts till the script is completed.
Built-in Namespace: This namespace contains the names of built-in functions and exceptions.
