A Python Calculator Application utilizing C++ for calculations with Qt/QML interface. The program follows the MVVM or MVP pattern, adheres to Google Code Style, and separates business logic appropriately.

This project is a calculator application written in Python 3.12 with a Qt/QML interface. The calculation logic is implemented in C++17 using a dynamic library, and the integration between Python and C++ is achieved using ctypes. The project structure also includes a CMake build system for the C++ component.

• Python 3.12
• C++17 compiler
• Qt/QML

• make all (default): Build the project.
• make build: Build the C++ calculation library.
• make rebuild: Clean and rebuild the C++ library.
• make uninstall: Remove build artifacts.
• make clean: Clean the project directory.
• make environment: Create Python virtual environment and install dependencies.
• make run: Run the calculator application.

• lib/calculation: C++ calculation library source code.
• view: Qt/QML interface files.
• main.py: Python script for running the calculator.
• requirements.txt: Python dependencies.

The C++ calculation library (calculation.h, calculation.cc) provides the core logic for parsing and evaluating mathematical expressions. It supports basic operations, functions, and constants.

The Qt/QML interface is defined in the view/main.qml file, and the Python script (main.py) handles the integration between Python and C++.

To build the C++ calculation library, run the following commands:

make build

Create a virtual environment and install the required Python dependencies:

make environment

Run the calculator application:

make run

This will start the Qt/QML interface with the calculator.

To remove build artifacts and Python cache files, run:

make clean
