Installing Python 3.9.4 and PyQt 5: Part 1 of 2

In this tutorial, we will guide you through the process of installing Python 3.9.4 and PyQt 5 on your system. Python is a popular programming language that is widely used for various applications, and PyQt is a set of Python bindings for the Qt application framework.

Part 1 of this tutorial will cover the installation of Python 3.9.4 on your system. Part 2 will cover the installation of PyQt 5.

Step 1: Download Python 3.9.4
The first step in installing Python 3.9.4 is to download the installer from the official Python website. Go to https://www.python.org/downloads/ and click on the "Download Python 3.9.4" button. This will start the download of the Python installer for your operating system.

Step 2: Install Python 3.9.4
Once the installer is downloaded, double-click on it to start the installation process. Follow the prompts in the installer to set up Python 3.9.4 on your system. Make sure to check the box that says "Add Python 3.9 to PATH" during the installation process, as this will allow you to run Python from the command line.

Step 3: Verify the installation
To verify that Python 3.9.4 has been installed correctly, open a command prompt and type "python –version" (without the quotes). You should see the version number of Python displayed, indicating that Python 3.9.4 is installed on your system.

Step 4: Set up a virtual environment (optional)
Setting up a virtual environment is a good practice when working with Python projects, as it allows you to isolate your project’s dependencies from other projects on your system. To create a virtual environment, open a command prompt and run the following command:

python -m venv myenv

This will create a new virtual environment named "myenv" in the current directory. To activate the virtual environment, run the following command:

On Windows:

myenvScriptsactivate

On macOS and Linux:

source myenv/bin/activate

Step 5: Install PyQt 5 (Skip this step for Part 1)
PyQt 5 is a set of Python bindings for the Qt application framework that allows you to create desktop applications with Python. To install PyQt 5, you can use the pip package manager that comes with Python. Run the following command in your command prompt:

pip install PyQt5

This will download and install the PyQt 5 package and its dependencies on your system.

That’s it for Part 1 of this tutorial! In Part 2, we will cover the installation of PyQt 5 and how to create a simple GUI application using Python and PyQt. Stay tuned for the next part of the tutorial!
