【Python】 list dict数据合并汇总demo
需求：
-
将列表a,根据company进行分类，同一个company的id放到一个列表里面
数据：
a = [{"id": 214,"company": "CN920A"},{"id": 225,"company": "CN920A"},{"id": 239,"company": "CN920A"},{"id": 226,"company": "CN920E"},{"id": 236,"company": "CN920E"},{"id": 194,"company": "CN920E"},{"id": 193,"company": "CN930D"},{"id": 192,"company": "CN930D"},{"id": 191,"company": "CN940F"},{"id": 190,"company": "CN940F"}]
代码：
def data_merge(a):classified_case_sensitive = {}for item in a:company = item['company']item_id = item['id']if company not in classified_case_sensitive:classified_case_sensitive[company] = []classified_case_sensitive[company].append(item_id)print(classified_case_sensitive)if __name__ == '__main__':data_merge(a)
结果：
{‘CN920A’: [214, 225, 239], ‘CN920E’: [226, 236, 194], ‘CN930D’: [193, 192], ‘CN940F’: [191, 190]}
