What is Selenium?

Selenium is an open-source, automated testing framework which is used to automate web browsers.

It allows the developers and testers to write scripts in different programming languages (like Java, Python, C#, etc.).

This is to replicate the user actions on a website, like clicking links, filling out forms, and navigating between pages.

A selenium also provides a compatible of tools for testing web applications across different browsers and operating systems.

Furthermore, the selenium is generally used in the software industry for testing web applications.

Securing their functionality, performance, and reliability.

It is also used for web scraping and data extraction tasks.

Solution 4: Installed Selenium Module in Ubuntu
The following command to install the selenium module on Ubuntu

sudo apt install selenium

What is the difference Between ImportError and ModuleNotFoundError?

The difference between ImportError and ModuleNotFoundError is that the ImportError is a general exception that is occurred when an import statement fails for any reason.

Meanwhile, the ModuleNotFoundError is the common exception that was introduced in Python 3.6.

It occurs if an import statement fails because the specified module cannot find in any of the locations.

Where Python searches for modules. For example, the directories recorded in the sys.path variable.

Check if the module selenium is installed

You can check if you have installed the selenium module by executing the command:

pip show selenium

After you run the above command, it shows the package is not installed.

It will show information about the package, including the name, version, license, and the location where the package is installed.

Frequently Asked Questions

What is Python ModuleNotFoundError and what causes it?

ModuleNotFoundError (a subclass of ImportError) is raised when Python cannot find the module you tried to import. Common causes: the package isn’t installed (pip install missing), wrong virtual environment activated, typo in module name, or Python can’t find your local module on the import path. The error message names exactly which module is missing.

How do I fix ‘ModuleNotFoundError: No module named X’?

Run pip install X first. If that succeeds but you still get the error, check which Python you’re using (which python OR python –version) vs which pip (which pip OR pip –version), they must match. Common gotcha: pip points to system Python 3.9 but you’re running python3.11 in a venv. Inside the venv, use python -m pip install X to be sure pip matches the active Python.

Why does my code work in one environment but not another?

Different Python versions or different installed packages. To diagnose: pip freeze > requirements.txt on the working environment, then pip install -r requirements.txt on the broken one. Use virtualenv (python -m venv venv) or conda for every project to avoid system-wide package collisions.

Is ModuleNotFoundError the same as ImportError?

ModuleNotFoundError is a subclass of ImportError added in Python 3.6. It specifically means ‘no such module exists.’ Plain ImportError covers a wider set: module exists but a name inside it can’t be imported (e.g. ‘cannot import name X from Y’). except ImportError catches both; except ModuleNotFoundError catches only the missing-module case.

Where can I find more ModuleNotFoundError fixes?

Browse the ModuleNotFoundError reference hub for 198+ specific module fixes (TensorFlow, Flask, Django, pandas, numpy, etc.). For related issues see ImportError. For broader Python setup see Python Tutorial hub.
