Load listing data from two sheets

The import process is just as intuitive when using the sheet_names attribute of a pd.ExcelFile() object.

Passing in a list as the sheetname argument of pd.read_excel(), whether you assign the list to a variable holding the sheet_names attribute of a pd.ExcelFile() object or type the list out yourself, constructs a dictionary. In this dictionary, the keys are the names of the sheets, and the values are the DataFrames containing the data from the corresponding sheet. You can extract values from a dictionary by providing a particular key in brackets.

In this exercise, you will retrieve the list of stock exchanges from listings.xlsx and then use this list to read the data for all three exchanges into a dictionary. pandas has been imported as pd.

Create a pd.ExcelFile() object using the file 'listings.xlsx' and assign to xls.
Save the sheet_names attribute of xls as exchanges.
Using exchanges to specify sheet names and n/a to specify missing values in pd.read_excel(), read the data from all sheets in xls, and assign to a dictionary listings.
Inspect only the 'nasdaq' data in this new dictionary with .info().
