What is namespace:

A namespace is a system that has a unique name for every object in Python. An object may be a variable or a method. Python itself maintains a namespace in the form of a Python dictionary. Let us look at an example, the directory file system structure in a computer. Needless to say, there can be multiple directories, each with a file with the same name. However, as long as the absolute path of the file is specified, it can be directed to the file.

For real-time examples, the namespace acts like a surname. A person may not find one "Alice" in class, and there may be multiple "Alices", but when you specifically ask for "Alice Lee" or "Alice Clark" (with a surname), only There will be one (not for now) t think that multiple students have the same first name and last name). In similar lines, the Python interpreter understands the exact method or variable that is trying to point to the code based on the namespace. Therefore, the division of the word itself will provide more information. Its name (representing name, unique identifier) ??+ space (representing content related to the scope). Here, the name can be any Python method or variable, and the space depends on where you are trying to access the variable or method.

In Python, a namespace is a collection of identifiers (variables, functions, classes, etc.) that are grouped together based on their naming conventions. It serves as a container for the identifiers in a program and helps avoid naming conflicts.

Python has four types of namespaces: the built-in namespace, the global namespace, the local namespace, and the nonlocal namespace. The built-in namespace contains built-in functions and modules, such as print() and math. The global namespace contains variables and functions defined at the top-level of a module or in the global scope. The local namespace contains variables and functions defined within a function or method. The nonlocal namespace is used to access variables defined in the enclosing scope.

Scope refers to the region of the program where a particular namespace can be accessed. In Python, variables declared inside a function have local scope, which means they can only be accessed within that function. Variables declared outside a function have global scope and can be accessed throughout the entire module.

Python's namespace and scope rules help programmers organize their code and prevent naming conflicts. It is important to understand the rules to avoid unintended consequences and make your code easier to read and maintain.
