How To Make A Software Using Python

In this tutorial, we will learn how to make software using the widely popular and versatile programming language, Python. Famously known for its readability and simplicity, Python serves as the perfect choice for beginner programmers who wish to develop software applications and scripts.

Preparing the Development Environment

Step 1: Install Python

To get started, you’ll first need to install Python on your computer. Visit the official Python website and download the appropriate installer for your operating system: Python Download. Follow the installation instructions, making sure to check the box that says “Add Python to PATH” during the installation process. This will make it easier to run Python from the command line.

Step 2: Set up a Text Editor or IDE

Next, you’ll need a suitable text editor or Integrated Development Environment (IDE) to write your Python code. There are several options available, including:

Choose one that best suits your needs and preferences, download, and install it.

Creating a Simple Python Program

Step 3: Write a Simple Python Script

Now that your development environment is set up, it’s time to create your first Python script. Using your chosen text editor or IDE, create a new file called “hello_world.py” and add the following code:

Save the file and open a terminal or command prompt window.

Step 4: Run the Python Script

In your terminal or command prompt, navigate to the directory where you saved the “hello_world.py” file and run the following command:
bash
python hello_world.py. You should see the following output:

Hello, world!

Congratulations! You’ve just created and run your first Python program.

Creating a Python GUI Application

Step 5: Install the PyQt5 Package

Now let’s create a simple Python GUI application using the PyQt5 library. PyQt5 is a widely used Python library for developing desktop applications with graphical user interfaces (GUIs). First, you’ll need to install the PyQt5 package using the following command:
bash
pip install PyQt5This will install the necessary PyQt5 modules and dependencies.

Step 6: Write a Python GUI Application

Create a new Python file called “gui_app.py” and add the following code:

In this code, we first import the necessary modules and then create a MainWindow class, which is derived from QMainWindow class to define our main application window. We also set the window’s title and provide its initial size and position using the setWindowTitle and setGeometry methods. We then create a QLabel widget set its text and add it to the main window.

The main function creates an instance of the QApplication class initializes an instance of the MainWindow class, shows the main window, and starts the application’s event loop using app.exec_().

Save the “gui_app.py” file.

Step 7: Run the Python GUI Application

Back in the terminal or command prompt, navigate to the directory where you saved the “gui_app.py” file and run the following command:
bash
python gui_app.py
A new window should appear, displaying the text “Hello, world!”.
