Python is a powerful programming language used for various purposes, including web development, data analysis, and artificial intelligence. One of the key features of Python is its use of namespaces.

A namespace is a collection of identifiers that are used to identify variables, functions, classes, and other objects in a program. Namespaces help to organize code and prevent naming conflicts.

Types of Namespaces

In Python Classes in Kolhapur, there are two types of namespaces: local and global. Local namespaces are created when a function is called and destroyed when the function returns. Global namespaces are created when a module is imported and destroyed when the program exits.

Each module has its own global namespace, which is separate from the global namespace of other modules. This helps to prevent naming conflicts between modules.

Variable Scope

Variables in Python Training in Kolhapur have a scope that determines where they can be accessed. Variables defined inside a function have local scope and can only be accessed within that function. Variables defined outside of any function have global scope and can be accessed anywhere in the program.

If a variable is defined with the same name in both the local and global namespaces, the local variable takes precedence within the function. To access the global variable within the function, the 'global' keyword can be used.

To use functions and classes defined in another module, that module must be imported. When a module is imported, its global namespace becomes part of the importing module's global namespace.

To prevent naming conflicts when importing modules, it is common to use an alias for the module name. This can be done using the 'as' keyword when importing the module.
