Pythonic Guide: Importing Modules with importlib.import_module
Introduction
Python is a popular programming language used for various applications like web development, scientific computation, and data analysis. It comes with an extensive standard library, and one important aspect of this library is module management. In this article, we are going to compare different ways of importing modules using the importlib.import_module function.
What are Modules in Python?
Modules are files that contain Python code, which can be accessed from other Python code. They provide a way of organizing related code and create namespaces to avoid naming conflicts. Python comes with many built-in modules such as math, os, and datetime, which can be used to perform various tasks.
Importing modules with import statement
The most common way of importing modules in Python is by using the import statement. This statement takes the name of the module and adds it to the current namespace.
Importing modules with from statement
The from statement is another way of importing modules in Python. This statement imports specific objects from a module into the current namespace. It is useful when you only need to use a few objects from a module.
Importing modules dynamically with importlib.import_module()
The importlib.import_module() function is a way of importing modules dynamically. It allows you to specify the name of the module as a string and returns the module object. This function is useful when you need to load a module that is determined at runtime.
Comparing Importing Modules with Different Methods
Let’s compare the three methods of importing modules using a table:
| Method | Advantages | Disadvantages |
|---|---|---|
import statement |
Easy to use, allows access to all objects in the module | May cause naming conflicts, loads the entire module even if only a few objects are needed |
from statement |
Allows you to import specific objects into the current namespace, reduces syntax clutter | May cause naming conflicts, only imports specified objects, making it difficult to access other objects in the same module |
importlib.import_module() function |
Allows dynamic loading of modules, avoids naming conflicts, can be used to load modules not available at compile time | More verbose syntax, requires the name of the imported module as a string, returns the entire module object |
Examples of Using importlib.import_module()
Let us now see how to use importlib.import_module() to import modules. Consider the following example:
mymodule = importlib.import_module('mymodule')
Here, we are importing the module mymodule.py dynamically using its name as a string. Once the module is loaded, we can access its attributes like any other module.
Importing modules from a package
A package in Python is a collection of related modules organized in a directory hierarchy. To import a module from a package, we use the dot notation.
mypackage.mymodule = importlib.import_module('mypackage.mymodule')
Here, we are importing the mymodule.py module from the mypackage package. The dot notation is used to specify the path of the module.
When to use importlib.import_module()
The importlib.import_module() function is useful in many cases. Some examples are:
- Loading plugins at runtime
- Loading modules based on user input or configuration files
- Loading modules only when they are needed to save memory and improve performance
Conclusion
In this article, we discussed different ways of importing modules in Python. We compared the three methods using a table and saw how to use the importlib.import_module() function to load modules dynamically. We also saw how to import modules from a package and discussed some use cases for importlib.import_module(). Overall, choosing the right method of importing modules depends on the specific requirements of your application.

The importlib module provides an implementation of the import statement, allowing you to programmatically import other Python modules. This module is part of Python’s standard library and is available in all versions of Python.
Importing modules in Python allows you to access functionality that is not included in the built-in functions of the language. It also allows you to organize your code into smaller, more manageable files, making it easier to read and maintain.
You can import a module in Python using the import statement followed by the name of the module. For example: import math. This will import the math module, which contains mathematical functions like sine, cosine, and square root.
The import statement imports an entire module, whereas the from-import statement allows you to import specific functions or classes from a module. For example, you could import just the sqrt function from the math module using from math import sqrt.
The syntax for importing a module using importlib.import_module is: module = importlib.import_module('module_name'). This will import the module with the specified name and assign it to the variable module.
One advantage of using importlib.import_module is that it allows you to import modules dynamically at runtime, rather than at the beginning of your program. This can be useful in certain situations, such as when you need to load a module based on user input or configuration settings.
