排序
# 1.对字典进行排序 dic_demo = { "2101": 1, "2102": 3, "2103": 2, } res = sorted(dic_demo.items(), key=lambda x: x[1], reverse=False) # 从小到大 # res [('2101', 1), ('2103', 2), ('2102', 3)] res = sorted(dic_demo.items(), key=lambda x: x[1], reverse=True) # 从大到小 # res [('2102', 3), ('2103', 2), ('2101', 1)] # 2.对数组进行排序 arr = [ {"name": "小明", "age": 18}, {"name": "小红", "age": 99}, {"name": "木木", "age": 22}, ] res = sorted(arr, key=lambda x: x["age"], reverse=False) # 从小到大 # res [{'name': '小明', 'age': 18}, {'name': '木木', 'age': 22}, {'name': '小红', 'age': 99}] res = sorted(arr, key=lambda x: x["age"], reverse=True) # 从大到小 # res [{'name': '小红', 'age': 99}, {'name': '木木', 'age': 22}, {'name': '小明', 'age': 18}]
