Step 5: Choose the Python Version

When you run the installer, you will be prompted to choose the Python version. Here are the steps:

• Select the Python version that matches your needs (e.g., Python 3.9.5).
• Click on the "Install" button to start the installation process.

Step 6: Verify the Installation

Once the installation is complete, you need to verify that Python is installed correctly. Here are the steps:

• Open a new Terminal window.
• Type python --version and press Enter.
• If Python is installed correctly, you should see the version number (e.g., Python 3.9.5).

Step 7: Install Required Packages

To use Python, you need to install required packages such as pip and numpy. Here are the steps:

• Open a new Terminal window.
• Type pip install numpy and press Enter.
• Type pip install pandas and press Enter.
