Python通过变量中的键获取/设置dicts的dict值

Question

I have dict of dicts in Python, it can be deep, not just 2 levels.

data = {
    0: {
        1: {
            2: "Yes"
        },
        3: {
            4: "No"
        }
    },
}

I need to get and set the data, but the key is dynamic and is stored in list

key_to_get = [0,1,2]

print(data.get(key_to_get))

Should print Yes

Ideas?

Answer 1

Here is a simple recursive function which solves the problem

def getValue(dict, keys):
    if len(keys) == 1:
        return dict.get(keys[0])
    return getValue(dict.get(keys[0]), keys[1:])

And an iterative approach if you're boring

temp = data
for key in key_to_get:
    temp = temp.get(key)
print(temp)
