Q & A

What is the purpose of using Visual Studio Code (VSCode) in the tutorial?

The tutorial uses Visual Studio Code (VSCode) as the code editor to write and run Python code on macOS. It's chosen for its features such as extensions for Python, syntax highlighting, and integrated terminal for coding and debugging.

Why is it necessary to install Python separately on macOS, instead of using the pre-installed version?

The pre-installed version of Python on macOS (Python 2.7) may not be compatible with modern libraries and frameworks. It's important to install a separate version, such as Python 3.x, to ensure compatibility and avoid conflicts.

How can you check the installed version of Python on macOS using the terminal?

To check the installed version of Python, you can open the terminal and type `python --version` or `python3 --version` to see the version number of the Python interpreter.

What is Homebrew, and why is it used in this tutorial?

Homebrew is a package manager for macOS that allows users to easily install and manage software. In this tutorial, it's used to install Python and other packages in a streamlined manner.

What is Pyenv, and how does it help manage different Python versions?

Pyenv is a tool that allows you to manage multiple versions of Python on your system. It simplifies the process of switching between different versions, making it easier to work with various projects requiring specific Python versions.

How do you install Pyenv on macOS?

To install Pyenv on macOS, you need to run a command in the terminal to install the script. The installation command can be copied from the official Pyenv website, and then you can use it to manage Python versions.

What does setting a global Python version in Pyenv do?

Setting a global Python version in Pyenv specifies the default Python version to be used across your system. This ensures that the selected version is used whenever you run Python commands.

How can you install Visual Studio Code (VSCode) on macOS?

To install Visual Studio Code on macOS, simply download the installer from the official VSCode website, run the installer, and follow the on-screen instructions to complete the setup.

What are Python extensions in Visual Studio Code, and why should they be installed?

Python extensions in Visual Studio Code enhance the functionality of the editor by adding features such as syntax highlighting, linting, debugging, and autocompletion, making it easier and more efficient to write Python code.

How can you create and run a Python program in VSCode?

To create and run a Python program in VSCode, you first create a new folder, then create a Python file (e.g., `main.py`). After writing your code, you can run it by using the integrated terminal in VSCode.
