Obtain the value and pythonvalue of a key when the python dictionary is nested.

Obtain the value and pythonvalue of a key when the python dictionary is nested.

Recently, a test program that writes an interface using python used a parsing dictionary to obtain the value of a key. Because the dictionary format returned by multiple interfaces is not fixed, multiple layers of nesting exist. In the dictionary method, I did not find a method that can directly achieve the goal (or because I did not know much about the dictionary method), so I wrote a program myself.
