 **The following files are included:**
 
 - `tutorial_code.ipynb` is a Jupyter Notebook containing all the code used in the tutorial.
 - `rides.parquet` contains taxi fare data used throughout the tutorial. [See below]
 - `taxi_rides_nnGB.py` are a series of Python scripts that will generate a local copy of the `2021_Yellow_Taxi_Trip_Data.csv` in different sizes. This is used to illustrate data streaming and is provided to help demonstrate streaming.
 - `programming_languages.csv` is a small file used to illustrate the conversion between a DataFrame and a LazyFrame.
-- `dataframe_timer.py` and `lazyframe_timer.py` are two scripts used to compare the speed differences when using both a DataFrame and LazyFrame to perform an analysis.
