What is namespace and scopes in Python?

namespace in python

Here, we will discuss Python’s namespaces, namespace types, and namespace scopes. Python is object-based. What we call anything is called by its name. And that “space” is just the object’s main memory address. A namespace is the set of all possible names for a given address in the main memory. Python’s namespaces are built-in, global, and local (the default for a single module). namespace in python can use all others. Namespaces regulate variable usage. In the following sections, you’ll find more information on this topic:

Python Namespaces

1 – Define

We name everything to distinguish it from others. Identifiers are labels in Python. A name is only a label. Main memory stores each name, its context, and its value. Space. Namespace stores Python object names and values. Python dictionary stores namespace. In Python, namespaces work like dictionaries, with names as “keys” and “values” reflecting real data.

2 Namespace Instance In Python

The file system structure best illustrates namespaces. Same-file duplicates exist. File addresses help locate files. The phonebook is a good example of python’s namespace. There are so many possible results for John’s phone number. We can check the right box if we know John’s last name. In Python, a person’s name is an identifier, and their location determines physical space.

Python Namespaces: Three Varieties


Even without user-defined functions, classes, or modules, the Python interpreter has input(), print(), and type(). These namespaces are not extensions; they are standard to Python.

Naming Context Worldwide 2

All of a module’s namespaces are formed when it’s initialised; the default namespaces are accessible via the global namespace.

Local Namespace (3)

Local namespaces are those that are created by a function when it is created. An application working in a local namespace has access to both the global and the system namespaces.

Make a new domain name

The print() method can be invoked from global and local namespaces. We created namespace x globally and y locally.

Python’s Scopes

A thing’s usefulness determines how long it will last. Python’s scope of variables expires when the object’s lifetime does. Python scopes are code sections with direct namespace access.

Different Scopes

Priority One: Focus on the Neighborhood

In Python, a function-scoped variable has only that function’s scope.

Global Perspective

A variable declared inside a Python module has global scope in the language.

Third, Integrated Zoom

We are working within a built-in scope when we can call methods like print(), type(), and input() without defining any new modules or UDFs. Loaded or created scripts with built-in scope

Fourth, Internal Functioning Within the External

The variable is local to the function and any inner functions it may use.


The article covers Python namespaces and scope. Python’s namespaces and types are described. Everything has a name. And that “space” is just the object’s main memory address. A namespace is the set of all possible names for a given address in the main memory. Python has “built-in,” “global,” and “local” namespaces.
