With the continuous enrichment of online learning resources,students are prone to problems such as confusion of knowledge structure and learner"learning trek"when learning online resources.Knowledge graph plays an important role in educa-tion resource integration and knowledge recommendation.By adopting the innovative"knowledge-exercises-grades"model and combining advanced technologies such as ontology modeling,knowledge extraction and graph database storage,this study devel-oped a knowledge graph of junior high school Python curriculum with in-depth analysis of teaching materials,crawling of network resources,accurate entity recognition and rigorous relationship definition as the core.Finally,a personalized learning platform based on Python curriculum knowledge graph is built to improve students'performance level and help students enhance their awareness of independent learning.
