The manuscript presents a study of resonance processes in electrical circuits with the Python programming language. Basic resonant circuits with series and parallel resonance are considered. The obtained results were compared and verified with computer simulations implemented with the popular LTspice program simulator. In this way, the possibilities of researching different electrical circuits with Python have been proven. This is convenient in view of Python's better data collection, processing and analysis capabilities compared to standard Spice-based simulators. In addition, the presented approach is useful for implementation in the learning process of software engineers, where it is important to use different software tools in the study of fundamental disciplines such as electrical engineering and electronics.
