代码在这里:
class WeirdSortee:
def __init__(self, string, number, sort_num):
self.string = string
self.number = number
self.sort_num = sort_num
def __lt__(self, object):
if self.sort_num:
return self.number < object.number
return self.string < object.string
def __repr__(self):
return"{}:{}".format(self.string, self.number)
a = WeirdSortee('a', 4, True)
b = WeirdSortee('b', 3, True)
c = WeirdSortee('c', 2, True)
d = WeirdSortee('d', 1, True)
l = [a,b,c,d]
l.sort() #returns [d:1, c:2, b:3, a:4]
for i in l:
i.sort_num = False
l.sort()
print(l) #returns [a:4, b:3, c:2, d:1]
我知道&lt; b&lt; c&lt;但是如何对自我和对象进行排序?在这种情况下,对象和自我是什么?
