You can check your Python installation path by running “python –version” or “which python” in the command line.
This article will help you understand how to find the Python installation location on your system, focusing on different methods and operating systems. This knowledge will assist you in setting up your programming environment correctly and provide a better understanding of how Python interacts with your machine.
Let’s get into it!
Python Installation Locations
On various operating systems like Windows, macOS, or Linux, Python’s installation location can vary due to user preferences or installation packages from different sources.
In this section, we’ll look at the installation location of Python for different operating systems. Specifically, we’ll look at the following:
- Python Installation location on Windows
- Python Installation location on MacOS
- Python Installation location on Linux
1. Python Installation Location on Windows
By default, Python installations on Windows are located in the C:\ directory or C:\Users\<User>\AppData\Local\Programs.
The common installation paths for both 32-bit and 64-bit versions may reside in the C:\PythonXX folder, where XX stands for the Python version (e.g., C:\Python27 for Python 2.7).
In newer installations, the 64-bit version is often located in the C:\Program Files\PythonXX folder, while the 32-bit version is in the C:\Program Files (x86)\PythonXX folder.
To find the exact location of your Python installation on Windows, you can use the command prompt by typing where python and press Enter. This command will display the file paths of any installed Python versions on your system.
The following image demonstrates this prompt:
2. Python Installation Location on MacOS
On macOS, Python is typically installed in the /Library/Frameworks/Python.framework/Versions directory, with different versions contained in their respective subfolders (e.g., /Library/Frameworks/Python.framework/Versions/3.9 for Python 3.9).
Alternatively, Python installations managed by Homebrew are located in /usr/local/Cellar/python.
To check the exact path of your Python installation, you can open the terminal and type which python or which python3. Pressing “Enter” will display the file path of the active Python version on your system.
3. Python Installation Location on Linux
In most Linux distributions, Python is installed by default and can be found in the /usr/bin/ directory. The installed versions usually include both Python 2 and Python 3.
For Python 2.x, the executable is named python, while for Python 3.x, it’s named python3.
For systems with multiple Python installations or custom installation paths, you can find the location by typing which python or which python3 in the terminal and pressing Enter.
The command will show the file path of the active Python version on your system.
In the next section, we’ll go over how you can use built-in Python modules to locate the Python folder in your system.
How to Use Python’s os and sys Modules to Locate Python Folder
Python’s os and sys modules are built-in modules that allow you to interact with the operating system.
To locate where Python is installed, follow the steps given below:
- Run Python interpreter by typing python in the terminal or command prompt.
- Execute the following commands:
import os
import sys
print(os.path.dirname(sys.executable))
This Python script is used to print the directory of the Python interpreter being used to execute the script. os.path.dirname(sys.executable) gets the path of the currently running Python interpreter.
The output is given below:
How to Check the Location of Python Executables
When you are working in Python, you’ll want to install libraries from time to time. In most cases, you might want to check the path of a certain library.
You can check the path of a Python library or executable with the pip package manager. To do this, open up CMD and run the following code:
pip show <package name>Let’s say I want to check the location of NumPy library on my operating system. To do this, I’ll type the following prompt in CMD:
pip show numpyThe output is given below:
How to Configure Python Path
When you first install Python on Windows, it’s important that you configure the path environment variable.
This means you should let your operating system know the path of your installation folder, which will allow the interpreter to refer to this path when running Python files.
We’ve listed a step-by-step guide to setting your environment variable and variables below:
Windows
- Right-click on ‘My Computer’ or ‘This PC,’ and select ‘Properties.’
- Click on ‘Advanced system settings.’
- Go to the ‘Advanced’ tab and click on ‘Environment Variables.’
- In the ‘System variables’ section, locate the ‘Path’ variable, select it, and click on ‘Edit.’
- Add the path to the Python executable (e.g., C:\Python<version>\Scripts;C:\Python<version>), and click ‘OK.’
macOS and Linux
- Open the terminal (Terminal on macOS, and Ctrl + Alt + T on Linux).
- Edit the shell configuration file (~/.bashrc for bash shell, ~/.zshrc for zsh shell).
- Add the following line: export PATH=”/path/to/python-<version>/bin:$PATH”
- Save the file and restart the terminal for the changes to take effect.
How to Verify Python Version and Installation
Before starting any Python project, it’s essential to know the version of Python installed on the system as well as its location.
It’ll help you ensure compatibility between packages, libraries, and other tools.
This section will guide you through verifying your Python version and installation using various Python-related commands and performing cross-platform checks.
1. Python-related Commands
To find the version of Python installed on any platform, you can use the python –version command in the terminal or command prompt.
It returns the Python 2 version installed on your system. To check for the Python 3 version, you can use the python3 –version command instead. These commands help you determine which Python interpreter you are currently using.
In case you are using both Python 2 and Python 3 versions, you can verify the compatibility of a specific module by importing it into the Python interpreter.
For example, to check if the re module is compatible, you can try running the following command:
import re
print(re.__version__)When you run the above command, you’ll get an output similar to the following:
An output like the above suggests that Python’s re module is compatible with your current Python version.
