Exercise

Rounding up the G.S. crew

In chapter 2, you used a regular expression object Regex to find values that follow a pattern. We can also use the regular expression operator $regex for the same purpose. For example, the following query:

{ "name": {"$regex": "^Py"}    }

will fetch documents where the field 'name' starts with "Py". Here the caret symbol ^ means "starts with".

In this exercise, you will use regular expressions, projection, and list comprehension to collect the full names of laureates whose initials are "G.S.".
