Pythonic way to set sort order?
I have a collection on objects that I need to assign a random order. I wrote a pretty dumb java style loop to do it, but what is a fancier pythonic way to achieve the same?
from random import shuffle
class pair(object):
def __init__(self, name):
self.name = name
self.order = 0
def __repr__(self):
return self.name + " order: " + str(self.order)
test =[pair('a'),pair('b'),pair('c'),pair('d')]
print(test)
#shuffle the list
shuffle(test)
i = 1
#this is what i want to replace 开发者_如何转开发<------
for t in test:
t.order=i
i+=1
print(test)
Sample output:
>>>[a order: 0, b order: 0, c order: 0, d order: 0]
>>>[c order: 1, a order: 2, d order: 3, b order: 4]
This isn't a lot simpler than yours, but it's perhaps a little bit neater:
for i, t in enumerate(test):
t.order = i
[ x.order = o for o, x in enumerate(test) ]
