我必须使用任何排序功能排序权重。
class sample:
counter = 0
record=[{"studentname":"akshay", "studentid":"17905", "roomnum":"123", "height":"5.0","weight":"155"},
{"studentname":"naveen", "studentid":"1234", "roomnum":"45", "height":"5.5", "weight":"146"},
{"studentname":"rahul", "studentid":"34", "roomnum":"23", "height":"6.7", "weight":"170"},
{"studentname":"kiran", "studentid":"45", "roomnum":"43", "height":"5.8", "weight":"176"},
{"studentname":"sai", "studentid":"56", "roomnum":"12", "height":"5.9", "weight":"173"},
{"studentname":"giri", "studentid":"63", "roomnum":"65", "height":"6.1", "weight":"143"},
{"studentname":"pranoy", "studentid":"46", "roomnum":"56", "height":"6.8", "weight":"123"},
{"studentname":"phani", "studentid":"58", "roomnum":"23", "height":"6.2", "weight":"321"},
{"studentname":"nihar", "studentid":"37", "roomnum":"29", "height":"5.4", "weight":"43"},
{"studentname":"hitesh", "studentid":"45", "roomnum":"33", "height":"5.6", "weight":"145"}]
def __init__(self, studentname, studentid, roomnum, height, weight):
type(self).counter +=1
self.studentname = studentname
self.studentid = studentid
self.roomnum = roomnum
self.height = height
self.weight = weight
def PrintAllStudentsInWeight():
for i in range(len('weight')):
weight = sample.record
for j in range(len('weight') -1):
if weight[j] > weight[j+1]:
weight[j+1] = weight[j] = weight[j], weight[j+1]
print(weight)
PrintAllStudentsInWeight()
;请帮助，我是python的新手。
