A modular structure assists with maintainability.Similar functions and variables can be grouped within a module. Modules make it easier to structure code in an organized and efficient manner.They allow for the reuse of code, which speeds up development.Some of the reasons to use Python modules include the following: No further processing of the code is required. It can use the module’s functions and variables the same way as any other Python code. When an application imports a module, it has access to the entire contents of the module. Each module is also a Python namespace.Ī Python namespace is a dictionary of the object names and the actual objects. A module maintains its own symbol table, which serves as the global symbol table inside the module. py extension, for example, module_name.py. The filename for a module consists of the module name followed by the. Python modules are named the same way as other Python files. Python modules can be imported into the main module or other stand-alone modules. But programmers can also build their own modules or use modules from other developers. Some popular modules include the Python os module, time module, and math module. These modules are part of the Python Standard Library, also known as the Library Reference. Python includes some built-in standard modules.

The Python pip utility is used to install a module, but the import command is used to actually import the module. As the name suggests, modules are self-contained, and are designed to be reused by other applications.

Most applications and development projects use modules. This file can potentially include functions, variables, classes, constants, and executable code. An Introduction To Python ModulesĪ Python module is a file containing Python code. This guide provides an introduction to Python modules and explains how to install and import modules in Python.

A programmer can import this module and use its functions and variables in their application. Related functions and attributes are often grouped together as part of a Python module. Except for very short and simple programs, most Python applications contain code from many files, directories, and packages.
