The following are the stock symbols associated with their parent company.| Symbol | Parent Company || - | - || FB | Facebook, Inc. || AMZN | Amazon.com, Inc. || GOOGL | Alphabet Inc. (Google) || TSLA | Tesla, Inc. || AAPL | Apple, Inc. || SBUX | Starbucks, Inc. |All data contained within the files from from early September 2020 - early September 2021.Example reading of the file using Pandas:```pythondf = pd.read_csv('SBUX_Sept2020_Sept2021.csv', usecols=[0, 1, 2],                 converters={'Close/Last': lambda s: float(s.replace('$', ''))})```Here we are only going to read in the first three columns, and use a converter lambda function to get rid of the dollar sign and make the close values into a float type.<jupyter_code>import matplotlib.pyplot as plt
