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

Recently picked up Django Learning, example practice encountered in the multidimensional dictionary type data traversal operation problem, Google query no relevant information ... After all, the novice, to their own hands when found not simple to imagine, quite two twists and turns to achieve the final effect, the process of recording down hope for everyone useful. Instance data (multiple nesting): person = {"Male": {"name": "Shawn"}, "female": {"name": "Betty", "Age": "}", "Children":

Today encountered a problem, tangled up a period of time after finally think of a method, very happy, on record.The problem is simplified after this: for a list like this in Python[{' A ': 2, ' B ': 3, ' C ': 4},{' a ': 2, ' B ': 4, ' C ': 5},{' a ': 2, ' B ': 3, ' C ': 5},{' a ': 2, ' B ': 3, ' C ': 6}]where each element of the list is a dictionary with the same structure, I want to find out that the combination of a and B in the dictionary is the on
