PYTHON — Activating Virtual Environment in Python Terminal

# Activating a Virtual Environment in the Terminal
In this tutorial, you will learn how to activate a virtual environment using the activate script in Python. The lesson will also cover a method to check which third-party libraries are installed in the virtual environment.
When setting up a virtual environment, running pip3 would still execute inside the global environment. To address this, you will need to activate the virtual environment by running the activate script inside the venv/ folder. On Windows, this would be an executable command.
After activating the virtual environment, the prompt will change to indicate the activation. Subsequently, running which pip3 will point to a different path inside the virtual environment. This ensures that any installations are done within the virtual environment rather than the global environment.
You can also use the pip3 list command to view the installed packages within the virtual environment, which typically includes the standard library, pip, and setuptools.
For Windows users, the equivalent command to which pip3 would be where.exe pip.
In a scenario where a Python script is executed in a subdomain space but identifies the wrong version of Python, it could be due to not using the absolute path to the Python executable inside the virtual environment. This issue can be resolved by using the absolute path to the Python executable.
Similarly, to activate the environment on Windows, the command would be .\venv\Scripts\activate. For a more detailed guide and Windows-specific commands, refer to the associated tutorial.
By following these instructions, you can effectively set up and activate a virtual environment in the terminal for your Python projects.
By following this tutorial, you will be able to activate a virtual environment in the terminal using the activate script. The content provides clear instructions and code snippets for both Unix-based and Windows operating systems. The tutorial also addresses a common issue related to identifying the wrong Python version in a subdomain space, offering a solution to the problem.
