Modules
In Python, a module is simply a file that contains definitions and declarations of functions, classes, and so on. 1. 6. Modules — Python 3.11.3 documentation
Packages
A directory containing modules and an __init__.py file is known as a "regular package". __init__.pycan be empty. From Python 3.3, a directory without __init__.pycan be treated as a package. Such a package is called a "namespace package". 1. 5. The import system - Packages — Python 3.11.3 documentation
Libraries
Although not strictly defined, packages and modules are sometimes called libraries.
For example, import the mathmodule. 1. math — Mathematical functions — Python 3.11.3 documentation Using import , a module is imported as an object of the module type. You can check which file is imported with print( ). You can access functions and constants defined in the module using the syntax .
PEP8, the Python style guide, provides recommendations on how to write the importstatement. 1. PEP 8 - imports – Style Guide for Python Code | peps.python.org Keep in mind that PEP8 is a style guide; deviating from it won't cause your code to throw errors.
The from ... import ...syntax enables you to specifically import functions, variables, classes, etc., from a module.
The askeyword allows you to assign an alias when importing. Note that once an alias is assigned, you must use the alias instead of the original name. Here's an example of aliasing a module: And aliasing a variable: Certain libraries, such as NumPy and pandas, are conventionally imported with abbreviated names:
When importing modules from a package, the correct method may vary depending on the package's structure and __init__.py. Generally, the package's documentation will guide you on the correct approach. Here are some examples to demonstrate the various patterns.
ModuleNotFoundError
This error indicates that the module cannot be found. The issue might be an incorrect module name or a problem with the module search path. 1. Check and add the module search path with sys.path in Python As shown in the example of collections above, ModuleNotFoundError can also occur if you attempt to import a class instead of a module. In such cases, use fromto import a function or a class.
AttributeError
This error indicates that the imported module does not have the specified attribute. This might happen when the correct file is not imported. For example, when you use import , the Python interpreter first looks for a module with that name in the same directory as the currently executed script file. If it finds a file named .pyin that directory, it imports that file. 1. Check and add the module search path with sys.path in Python Use print( )to verify if...
Dec 11, 2023 · The Python module is a file consisting of Python code with a set of functions, classes, and variable definitions. The module makes the code reusable and easy to understand. The program that needs to use the module should import that particular module. In this article, we will discuss how to import a Python module given its full path. Different Ways
1 day ago · Modules can import other modules. It is customary but not required to place all import statements at the beginning of a module (or script, for that matter). The imported module names, if placed at the top level of a module (outside any functions or classes), are added to the module’s global namespace.
In the first line, import math, you import the code in the math module and make it available to use. In the second line, you access the pi variable within the math module. math is part of Python’s standard library, which means that it’s always available to import when you’re running Python. Note that you write math.pi and not just simply pi.

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.
