Abstract: Standing wave is one of the key knowledge points in the wave chapter．In response to the difficulty of accurately and intuitively displaying the dynamic changes of standing waves under different conditions in traditional experimental teaching，especially in complex situations involving amplitude and phase differences，this paper designs an interactive standing wave simulation platform based on Python language．For the waveform superposition process of three typical cases of " same amplitude，same initial phase"，" same amplitude，different initial phase"，and " different amplitude，same initial phase"，real-time adjustment of control parameters and dynamic display of synthesized wave waveforms are achieved through an interactive GUI interface，transforming the pumping theory into a visually presented dynamic scene，deepening students ＇understanding and mastery of the essential characteristics of standing waves，and providing useful support for educational digital practice．
