如何在压缩后保持字典的整洁

Question

当只有大约1、2或3个元素时，字典会正确地保持顺序

>>> a = ["dorian", "strawberry", "apple"]
>>> b = ["sweet", "delicious", "tasty"]
>>> c = dict(zip(a, b))
>>> c
{'dorian': 'sweet', 'strawberry': 'delicious', 'apple': 'tasty'}

但是当超过3个元素时，顺序就被打破了

^{pr2}$

有人能解释一下为什么会这样吗？谢谢

Answer 1

Python^{}s are unordered。请改用^{}。在

from collections import OrderedDict as odict

# ...
c = odict(zip(a, b))
