How to Install Python on macOS Sonoma/Ventura

Do you want to install Python for Mac? If you're not too familiar with programming languages, you might not know what Python is. Its versatility and numerous benefits make it a favorite among programmers.

While Python boasts numerous advantages, its utility on a MacBook Pro/Air is particularly beneficial. Python has an extensive library and is easy to learn. Being platform-agnostic, it poses no issues running on a Mac, whether it's on macOS Sonoma or Ventura.

One of the main advantages of using Python on a Mac is its Unix foundation. The powerful hardware and software allow programmers to have an excellent coding experience. In this guide, we will delve into how to install Python on a Mac and run Python scripts.

Check for Python Pre-installed on Your Mac

First, you need to check if Python is already installed on your system. To do this, follow these steps:

1. Open "Terminal." You can find it by going to "Applications" > "Utilities" > "Terminal."

Second step: Type python3.

Step 3: If you see a message that says "Python 3.x.x," this means Python is installed, with "3.x.x" representing the version number of Python.

If you get an error message saying Python was not found, it means it is not pre-installed on your system.

To install Python on your Mac using the terminal, follow these steps: 1. **Open Terminal**: You can do this by using Spotlight Search (press `Cmd + Space`), typing "Terminal," and then hitting Enter. Alternatively, you can find it in the Utilities folder within the Applications folder. 2. **Update macOS**: Before installing any new software, it's good practice to ensure your system is up to date. Run the following command to update your macOS: ``` sudo softwareupdate -i -a ``` You'll be prompted for your password; enter it when requested. 3. **Install Homebrew**: Homebrew is a package manager for macOS that will help you install Python easily. If you haven't installed Homebrew yet, run: ``` /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" ``` 4. **Verify Homebrew installation**: Once the installation is complete, check if Homebrew is installed correctly by running: ``` brew doctor ``` 5. **Install Python**: By default, macOS comes with Python 2 and Python 3 pre-installed. To install the latest version of Python 3, use: ``` brew install python ``` 6. **Check Python version**: After installation, verify the Python version by running: ``` python3 --version ``` This should display the installed Python 3 version. Now you have Python 3 installed on your Mac via the terminal. Remember, Homebrew also allows you to manage and update Python packages easily.

Another way to install Python on your Mac is through the Terminal. Terminal's simplicity and efficiency make it a favorite among Mac users. Here, you can install Python system-wide using commands for Xcode and Homebrew.

Method 1: Installing Python on an M1 Mac using Xcode

Yet, if you're a beginner Mac user, the Terminal can be dangerous: you might accidentally use it to delete files.

In this case, you can't recover permanently deleted files from Mac Terminal unless you use a professional data recovery tool like tools Data Recovery Wizard for Mac. This utility can recover permanently deleted files that were removed by the command line.

With the tools Data Recovery software, you can quickly recover your data with just a few simple clicks:

Step 1: Launch the Mac Data Recovery Wizard, and select the hard drive where you lost your data. Click “Search for Lost Files” to begin scanning.

Select a location and click “Search Lost Files”.

Step 2: The software will automatically scan for lost data on your MacBook/iMac. After the scan is complete, you can filter the required data using the "Type" and "Path" buttons.

Step 3. Preview the file by double-clicking it. Then, click the "Recover" button to restore your lost data to another location.

To run a Python script and check its installation on a Mac, follow these steps: 1. **Open Terminal**: You can find Terminal in the Applications > Utilities folder or by using Spotlight search (press `Cmd + Space` and type "Terminal"). 2. **Navigate to the script's directory**: Use the `cd` (change directory) command to navigate to the location where your Python script is saved. For example, if your script is in a folder named "Documents/PythonScripts" and the script file is called "myscript.py", you would type: ``` cd Documents/PythonScripts ``` 3. **Run the Python script**: To run the script, use the following command, replacing "myscript.py" with the actual name of your script: ``` python3 myscript.py ``` If you have an older version of Python installed and `python3` doesn't work, try `python`. 4. **Check Python installation**: To verify the Python version installed, you can run: ``` python3 --version ``` This will display the installed Python version. Remember, ensure that you have Python 3 installed on your Mac, as it comes pre-installed from macOS Mojave onwards. If you need to install or update Python, you can visit the [Python website](https://www.python.org/downloads/) for the latest version.

After installing Python on your Mac, you can use the built-in Terminal app to run Python scripts to verify that the installation was successful. Here's how: 1. Open the "Applications" folder on your Mac. 2. Locate and open the "Utilities" folder. 3. In the Terminal app's command-line interface, type `python3` or `python` (depending on your Python version) and press Enter. 4. If Python is installed correctly, you'll see a prompt similar to `Python X.Y.Z>`, where X.Y.Z represents the version number of Python you have installed. 5. Now, try running a simple Python command like `print("Hello, World!")` and press Enter. If everything is working correctly, the terminal should display "Hello, World!". 6. Type `exit()` and press Enter to exit the Python interactive mode. If you've completed these steps without issues, congratulations – Python has been successfully installed on your Mac!

Step 1: Open the "Terminal."

Step 2: Change into the directory with the cd command, for example, cd ~/scripts.

Step 3: You should now be in the script's directory.

Step 4: Run the Python script as an argument to the `python3` command, like this: python3 HelloWorld.py.

Step 5: You should see the output "Hello World", which means that Python is installed and working correctly on your Mac.

If the Python installation on your Mac fails, there are two main culprits: lack of storage space and permission denied on Mac. In this case, you should first check your Mac's RAM, free up storage on your Mac to reinstall Python, or inspect the permission settings for installations on your Mac.

Conclusions

Installing Python on your Mac is a great idea. The many benefits of this programming language make it a natural choice for Mac users. Plus, it's easy to install Python, regardless of which version of macOS you're running.

For example, you can visit the Python website and download an installer from there. Alternatively, you can use the Terminal to install Python, either with XCode or Homebrew, both of which are very straightforward options that will make installing Python a breeze.
