Certainly! If you're using a Mac and want to set Python 3 as the default Python version, you can follow these steps. By default, macOS comes with Python 2.x installed, but it's recommended to use Python 3 for compatibility and support reasons. The steps below guide you through the process of making Python 3 the default on your Mac.
Homebrew is a package manager for macOS that makes it easy to install and manage software packages, including Python.
Open Terminal and run the following command to install Homebrew:
Follow the instructions that appear in the Terminal to complete the installation.
Now that Homebrew is installed, use it to install Python 3:
This command installs Python 3 and pip (the package installer for Python) using Homebrew.
To ensure that the newly installed Python 3 takes precedence over the system's Python 2, you need to update your shell profile file (usually ~/.bash_profile, ~/.bashrc, or ~/.zshrc if you're using Zsh).
Open the profile file using a text editor. For example, using nano:
Or using VSCode:
Add the following line to the file:
Save the file and exit the text editor.
Close and reopen your Terminal or run the following command to apply the changes:
Now, check that Python 3 is the default version:
You should see output indicating a version of Python 3.x.
It's a good practice to upgrade pip to the latest version:
Now you have successfully set Python 3 as the default Python version on your Mac.
Remember, these instructions assume you're using Bash as your shell. If you're using Zsh or another shell, modify the appropriate profile file (e.g., ~/.zshrc).
Feel free to adapt these instructions to your specific preferences and environment.
