Exercise

Opening a private file

The City Council wants to see the bigger trend and have asked Sam to total up all the requests since the beginning of 2019. In order to do this, Sam has to read daily CSVs from the 'gid-requests' bucket and concatenate them. However, the gid-requests files are private. She has access to them via her key, but the world cannot access them.

In this exercise, you will help Sam see the bigger picture by reading these private files into pandas and concatenating them into one DataFrame!

She has already initialized the boto3 S3 client and assigned it to the s3 variable. She has listed all the objects in gid-requests in the response variable.
