Usage
Let’s start with an example on how to find the diff between two dictionaries using
diff()
method:
from dictdiffer import diff, patch, swap, revert
first = {
"title": "hello",
"fork_count": 20,
"stargazers": ["/users/20", "/users/30"],
"settings": {
"assignees": [100, 101, 201],
second = {
"title": "hellooo",
"fork_count": 20,
"stargazers": ["/users/20", "/users/30", "/users/40"],
"settings": {
"assignees": [100, 101, 202],
result = diff(first, second)
assert list(result) == [
('change', ['settings', 'assignees', 2], (201, 202)),
('add', 'stargazers', [(2, '/users/40')]),
('change', 'title', ('hello', 'hellooo'))]
Now we can apply the diff result with patch() method:
result = diff(first, second)
patched = patch(result, first)
assert patched == second
Also we can swap the diff result with swap() method:

对比两个深层的 dict
输入两个 dict。返回值分别为：data_1 所独有的键值对， data_2 所独有的键值对，两个 dict 均有的 key 的对比结果。
def compare_data(data_1, data_2):
对比两个 dict。

下面先给大家介绍下Python 3 判断2个字典相同的方法，
Python自带的数据结构dict非常好用，之前不知道怎么比较2个字典是否相同，做法是一个一个key比较过去。。。
现在想到可以直接用==进行判断！！！
a = dict(one=1, two=2, three=3)
b = {'one': 1, 'two': 2, 'three': 3}
c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
d = dict([('two', 2), ('one', 1), ('three', 3)])
e = dict({'three': 3, '
假设背包的存储结构是这样的。
是一个字典，{物品id:数量}。
在背包类初始化的时候，把背包物品信息copy保存到一个oldbag变量，进行一些物品操作后(比如使用物品，领取物品奖励等)，在调用save()方法存进redis时，对新的bag字典与oldbag字典进行差异对比就得出变动情况了。
千言不如一码。
