1

Inspect the Structure

Print or pprint to see the nesting depth.

3

Drill to Key Metrics

Chain dict accesses: data['quote']['regularMarketPrice'].

4

Use Optional Chaining

data.get('quote', {}).get('price') avoids KeyErrors on missing keys.

For your first challenge today, I'd like you to take a look at this data dictionary that we got back and try to see if you can find the data for this date.

For your first challenge today, I'd like you to take a look at this data dictionary that we got back and try to see if you can find the data for this date. It's on that data variable somewhere, and it will end up being something like this: a dictionary with the opening value for Apple at that time, the high that day, the low that day, the close that day, and the total volume of shares that day. If you can navigate that data variable—you can find this.

You can find the information for that date and see if you can print it out. We'll come back in just a moment and show you how we did it.
