Creating Your Own Python IDE in Python

In this article, we are able to embark on an adventure to create your personal Python Integrated Development Environment (IDE) the usage of Python itself, with the assistance of the PyQt library.

What is Python IDE?

Python IDEs provide a characteristic-rich environment for coding, debugging, and going for walks in Python packages. While there are many extremely good IDEs available, constructing your very own custom IDE may be a rewarding revel, allowing you to tailor the environment to your particular dreams.

Setting up the Project

In this article, we’re capable of using the PyQt framework, a set of Python bindings for Qt, to create a graphical purchaser interface for our IDE. PyQt lets in you to layout someone-satisfactory interface with functions like code enhancing, execution, and output display, all inside a single application window.

Installation of Necessary Libraries

To install the PyQt5 library use the below command.

pip install PyQt5

Example:

This Python code creates a basic Python Integrated Development Environment (IDE) using the ‘PyQt5’ library. Here’s a brief overview of its functionality:

1. It imports necessary modules, including ‘PyQt5’ for the graphical user interface (GUI) and contextlib to capture and display the code’s output.
2. The PythonIDE class defines the main window for the IDE. It includes a text editor for entering Python code, an output widget for displaying the code’s output, and a “Run” button to execute the code.
3. The run_code method is called when the “Run” button is clicked. It retrieves the Python code from the text editor, captures the code’s output, and displays the output in the output widget.
4. In the if __name__ == '__main__': block, it initializes the PyQt application, creates an instance of the ‘PythonIDE' class, and starts the application loop to display the IDE.

This code provides a simple GUI environment for entering and executing Python code, capturing and displaying the output, and handling exceptions. It serves as a foundation for a basic Python IDE using ‘PyQt5’

    def initUI(self):
        self.setGeometry(100, 100, 800, 600)
        self.setWindowTitle('Python IDE')

        self.text_editor = QTextEdit(self)
        self.text_editor.setGeometry(10, 10, 780, 300)

        self.output_widget = QTextEdit(self)
        self.output_widget.setGeometry(10, 320, 780, 200)

        self.run_button = QPushButton('Run', self)
        self.run_button.setGeometry(10, 530, 780, 30)
        self.run_button.clicked.connect(self.run_code)

    def run_code(self):
        code = self.text_editor.toPlainText()
        output_stream = StringIO()

        with contextlib.redirect_stdout(output_stream):
            try:
                exec(code)
            except Exception as e:
                print(e)

        output = output_stream.getvalue()
        self.output_widget.setPlainText(output)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ide = PythonIDE()
    ide.show()
    sys.exit(app.exec_())
