Methods to Know If Python Is Installed on Mac

Method 1: Check Python Installation via Terminal

Before checking if Python is installed, you should update your macOS Homebrew package manager. Homebrew is used to manage packages and software installation on Mac.

Step 1: Open the Terminal application by searching Terminal in Spotlight search or navigating to Applications > Utilities > Terminal.

Step 2: Type “brew update” in the Terminal application to update Homebrew to the latest version.

Step 3: Once Homebrew is updated, type “brew install python” to install the latest version of Python.

Step 4: To check if Python is installed, type “python –version” into the Terminal window. Press Enter.

Step 5: If Python is installed, the version of Python should appear in Terminal. If it is not installed, the Terminal window will display a message that python command not found.

Pros:
– Easy to perform
– Checking installation history
– Detailed information about the installed version available

Cons:
– May take some time to update the Homebrew package manager.
– If specific Python versions are installed, this method won’t be helpful.

Method 2: Using the Mac’s Terminal

Step 1: Open the Terminal application by searching Terminal in Spotlight search or navigating to Applications > Utilities > Terminal.

Step 2: Type “python –version” without quotes in the Terminal window and press Enter.

Step 3: If your Mac has Python pre-installed, the version of Python will be displayed in the Terminal window. If it is not pre-installed, it will show a message "Python not found".

Pros:
– Gives information about Python’s installation status.
– Quick & easy.

Cons:
– Sometimes shows a version error status due to various python installations on the system.

Method 3: Using Finder

Step 1: Open Finder and navigate to the Applications folder.

Step 2: Scroll down to find Python’s folder. If the Python’s folder is available in the Applications folder and the date column shows a recent date, then Python is installed in your Mac.

Pros:
– Simple & easy way to check python installation status.
– Gives Python installation date.

Cons:
– May not give the detailed information about the python installation.

Method 4: Checking Python in Xcode

Step 1: Go to Finder and search for Xcode app.

Step 2: Open Xcode, and you will see an Xcode navigation menu.

Step 3: Click on "Preferences…" in the dropdown menu and then click on the "Components" tab.

Step 4: Here, you will be able to see if Python is installed properly. If it is installed, it will show "Installed". If it’s not installed, you can click on "Install" to install Python.

Pros:
– Gives information on Xcode’s Python installation status
– Can install Python directly from Xcode.

Cons:
– Requires installation of Xcode software.
