python 二维 排序

# students = [(1,3), (2,2), (3,1)]
students = [[1,3], [2,2], [3,1]]
students=sorted(students, key=lambda s: s[1]) #按年龄排序

print(students)


#list.sort(func=None, key=None, reverse=False)
list = [(1,93),(2,71),(3,89),(4,93),(5,85),(6,77)]
print(list)
list.sort(key=lambda x:x[1])
print(list)
