student = [{"no": 1,"score": 90},{"no": 2,"score": 90},{"no": 3,"score": 88},{"no": 4,"score": 92}] # 单级排序，仅按照score排序 student_sort_1 = sorted(student, key=lambda e: e.__getitem__(‘score‘)) # 多级排序,先按照score，再按照no排序 student_sort_2 = sorted(student, key=lambda e:(e.__getitem__(‘score‘), e.__getitem__(‘no‘)))
