How to sort a list with struct data in python like this? [duplicate]

Question

I define a struct by class like this:

  class image:
  def __init__(self):
      self.address = ''
      self.label = 1
      self.storage = 1

Then, I put 100 stuct data into one list.

images = []
for i in range(100):
    single_image = image()
    single_image.address = 'xxx'
    single_image.label = 3 #1:5
    single_image.storage = 10 #1:100

How can I sort images by the storage?

This isn't a struct, is just a simple class.

Use operator

import operator
images.sort(key=operator.attrgetter('storage'))

import operator  
images_sorted = sorted(images,key=operator.attrgetter('storage'))

or you can sort images in place.

images.sort(images,key=operator.attrgetter('storage'))
