2 days ago · The import system¶ Python code in one module gains access to the code in another module by the process of importing it. The import statement is the most common way of invoking the import machinery, but it is not the only way. Functions such as importlib.import_module() and built-in __import__() can also be used to invoke the import machinery.

Mar 8, 2025 · In Python, modules allow us to organize code into reusable files, making it easy to import and use functions, classes, and variables from other scripts. Importing a module in Python is similar to using #include in C/C++, providing access to pre-written code and built-in libraries.

Imports in Python are important for structuring your code effectively. Using imports properly will make you more productive, allowing you to reuse code while keeping your projects maintainable. This tutorial will provide a thorough overview of Python’s import statement and how it works.

1 day ago · Such a file is called a module; definitions from a module can be imported into other modules or into the main module (the collection of variables that you have access to in a script executed at the top level and in calculator mode). A module is a file containing Python definitions and statements.

May 12, 2023 · Using import <module_name>, a module is imported as an object of the module type. You can check which file is imported with print(<module_name>). You can access functions and constants defined in the module using the syntax <module_name>.<function_name> or <module_name>.<constant_name>.

At its core, Python's import system allows you to access code defined in one module from another module. There are several ways to import code: # Use the module with namespace result = math.sqrt(16) # 4.0 # Import specific functions/classes/variables from math import sqrt, pi.

Summary: in this tutorial, you will examine the Python import statement variants and how they work under the hood. When you import a module, Python does two things: First, check if the module has been loaded and cached in the sys.modules. If not, it will execute the module and create a reference to the module object.
