Parsing data from dictionaries

When JSON data is loaded into memory, the resulting dictionary can be complicated. Key-value pairs may contain another dictionary, such are called nested dictionaries. These nested dictionaries are frequently encountered when dealing with APIs or other JSON data. In this exercise, you will practice extracting data from nested dictionaries and handling missing values.

The dictionary below is stored in the school variable. Good luck!

{
    "street_address": "111 Columbia Street",
    "city": "Manhattan",
    "scores": {
        "math": 657,
        "reading": 601
    }
}
