Understanding Namespaces and Scope in Python

This Article is about Understanding Namespaces and Scope in Python.

What is Namespace in Python

Namespaces and scope are two notions used by Python, a flexible and dynamic programming language, to control the appearance and accessibility of variables, functions, and objects. These ideas are essential for organizing code, avoiding naming conflicts and improving code structure. In this post, we'll go into the topics of understanding namespaces and scope in Python, discussing their importance and offering sample Python code to show how they work.

Types of Namespaces in Python

Local Namespace

When a function is called, the local namespace is formed and deleted when the function ends. The names of the arguments and variables defined within the function are contained in it. These variables can only be accessed from within the body of the function. One more call to the function creates a new local namespace.

Enclosing Namespace

When you have nested functions—that is, when one function is defined inside another—enclosing namespaces become relevant. Variables from the outer function's namespace are accessible to the inner function.

Global Namespace

The module or script as a whole is covered by the global namespace. The global namespace is where variables defined at the top of the module are located and can be accessed anywhere. You can learn Global Namespace in Python by enrolling in the Python Online Course at FITA Academy and be ready for a fast-paced, fascinating job.

Integrated Namespace

Python's built-in objects and functions are located in the built-in namespace. These names don't require importation or definition; they are always accessible. Examples include objects like lists and int and procedures like print(). 

What Does Python Scope Mean?

The area of a program where a use of namespace in python is available is defined by its scope. It establishes which names in a specific code location can be referenced. Python uses the LEGB (Local, Enclosing, Global, Built-in) rule to resolve names across namespaces. According to this rule, the interpreter will look for a name in that sequence's enclosing, global, and built-in namespace in python if it cannot be found in the local namespace.
