本文主要是介绍python list元素复杂排序，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！ 
student = [
{"sno":101, "sname":"小张", "sgrade":88},
{"sno":102, "sname":"小王", "sgrade":99},
{"sno":103, "sname":"小李", "sgrade":77},
{"sno":104, "sname":"小赵", "sgrade":66},
]
student_sort = sorted(student,key=lambda x: x["sgrade"])
print(student)
print(student_sort)

倒序排列：

student = [
{"sno":101, "sname":"小张", "sgrade":88},
{"sno":102, "sname":"小王", "sgrade":99},
{"sno":103, "sname":"小李", "sgrade":77},
{"sno":104, "sname":"小赵", "sgrade":66},
]
student_sort = sorted(student,key=lambda x: x["sgrade"], reverse=True)
print(student)
print(student_sort)
