“Find Where Python Is Installed (If It Isn’T Default Dir)” ~ bbaz
Python is a widely-used and praised programming language, frequently used for scripting, data analysis, machine learning, automation, and much more. There are various ways to install Python on your system, but default Python installations may not always meet your needs. This blog post will show you how to locate non-default Python installations and switch between them effortlessly without needing to modify your system’s environment variables.
|Virtual Environments||Easy to create, manage, and install packages||Space-consuming, may take time to set up|
|pyenv||Allows installing multiple versions of Python on the same machine||Requires additional installation steps|
|conda||Comes bundled with popular scientific libraries||Limited support for less popular packages|
|Pipx||Installs packages globally, but keeps them isolated from system installations||May require adding directories to system’s PATH|
What are default Python installations?
Default Python installations are the ones that come pre-installed with your operating system. They are typically located in the system’s root directories such as /usr/bin/python on macOS and Linux or C:\PythonXX\ on Windows. The default installations may include the Python interpreter, and sometimes a few pre-installed packages necessary for basic functionalities.
Why locate non-default Python installations?
There are several reasons why you might want to locate non-default Python installations.
Multiple versions of Python
If you need to work with different versions of Python depending on the project or application, installing multiple versions side-by-side can be necessary. Python versions can get deprecated, and not all packages might be available for all versions. By finding non-default Python installations, you can install and manage different versions of Python without interfering with your system’s default environment.
You may have a project that requires specific packages or package versions that conflict with those already installed. Or you may need to test out new features in a fresh environment. Finding and activating the relevant non-default Python installation is easier than adjusting the global environment variables.
Even with virtual environments, isolation is not guaranteed. Other programs that run on your operating system may still affect the environment and cause issues. By installing Python in a separate location, you reduce the likelihood of interference from other systems, such as updating the global Python version on your machine.
How to locate non-default Python installations
Here are four popular methods to discover and locate non-default Python installations.
1. Virtual Environments
A virtual environment is a self-contained Python environment created using the venv module. It allows you to install packages and dependencies for a specific project without touching your system’s default environment. To create a new virtual environment, enter the following command:
$ python -m venv myenv
To activate the virtual environment, enter:
$ source myenv/bin/activate
Pyenv allows you to install and use multiple versions of Python on the same system. It works by setting up a new user-level Python directory that will not interfere with your system’s default environment settings. Here’s how to install it:
$ curl https://pyenv.run | bash
Once installed, you can run the following command to install a specific version of Python:
$ pyenv install
Conda is a package and environment manager bundled with Anaconda and Miniconda. It is primarily used for data science, scientific computing, and machine learning workflows. Here’s how to install it:
$ curl -O https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh$ bash Miniconda3-latest-Linux-x86_64.sh
After installing, you can create and activate a new environment with the following command:
$ conda create --name myenv python=
$ conda activate myenv
Pipx is a python package installer that installs packages globally while keeping them isolated from your system’s environment variables. It provides a way to install command-line utilities as isolated Python environments outside of the global system paths. Here’s how to install it:
$ python3 -m pip install pipx
After installing, you can install packages and their dependencies via pipx. For example:
$ pipx install youtube-dl
As demonstrated in this article, finding and switching to non-default Python installations can be done effortlessly with the right tools. Verifying a few different methods helps you to decide which one suits your needs.
Virtual environments and conda are great options for package management and version control, while pyenv excels at managing multiple versions of Python. Also, Pipx is helpful if you need to install Python CLI packages globally, yet keep them isolated from the system’s environment variables.

As we have discussed in this article, there are several ways to locate non-default Python installations on your system. By understanding where different versions of Python are installed, you can more easily manage your Python environment and run the programs or scripts that require specific versions of the language.
Whether you are a seasoned developer or just starting with Python, knowing how to find and manage different installations of the language is an important skill to have. By following the methods outlined in this article, you can locate non-default Python installations with ease and continue to build and run amazing programs with Python!
Locating non-default Python installations can be a daunting task for beginners. Here are some frequently asked questions that people have about this topic, along with their corresponding answers:
1. How can I check which version of Python is installed on my computer?
- You can open your command prompt or terminal and type python –version. This will display the version number of the default Python installation.
2. How do I find out where Python is installed on my computer?
- You can open your command prompt or terminal and type which python (on Unix-based systems) or where python (on Windows-based systems). This will display the file path of the default Python installation.
3. How do I locate a non-default Python installation?
- If you know the file path of the non-default Python installation, you can use that to access it. Otherwise, you can search for Python in your file explorer and look for any folders or files that indicate a non-default installation.
4. Can I have multiple versions of Python installed on my computer?
- Yes, you can have multiple versions of Python installed on your computer. However, you will need to specify which version you want to use when running Python commands.
5. How do I set a non-default Python installation as my default?
- You can add the path of the non-default Python installation to your system’s environment variables. This will make it the default Python installation when running commands in the command prompt or terminal. However, be cautious when making changes to your system’s environment variables.
