Practice: Create a taxi_zones_file asset

To practice what you’ve learned, create an asset in trips.py that:

• Is named taxi_zones_file. This asset will contain a unique identifier and name for each part of NYC as a distinct taxi zone.
• Uses the requests library to obtain NYC Taxi Zones data from this link: https://data.cityofnewyork.us/api/views/755u-8jsi/rows.csv?accessType=DOWNLOAD
• Stores the data as a CSV in data/raw/taxi_zones.csv. This path is provided for you in constants.TAXI_ZONES_FILE_PATH.

Check your work

The asset you built should look similar to the following code. Click View answer to view it.

If there are differences, compare what you wrote to the asset below and change them, as this asset will be used as-is in future lessons.

@asset
def taxi_zones_file() -> None:
    """
      The raw CSV file for the taxi zones dataset. Sourced from the NYC Open Data portal.
    """
    raw_taxi_zones = requests.get(
        "https://data.cityofnewyork.us/api/views/755u-8jsi/rows.csv?accessType=DOWNLOAD"
    )

    with open(constants.TAXI_ZONES_FILE_PATH, "wb") as output_file:
        output_file.write(raw_taxi_zones.content)
