Load multiple data files

It's perfectly fine to manually import multiple datasets. However, there will be times when you'd want to import a bunch of datasets without having to make multiple read_csv() calls. You can use the glob library that is built into Python to look for files that match a pattern. The library is called "glob" because "globbing" is the way patterns are specified in the Bash shell.

The glob() function returns a list of filenames that match a specified pattern. You can then use a list comprehension to import multiple files into a list, and then you can extract the DataFrame of interest.

Obtain a list of all csv files in your current directory and assign it to csv_files.
Write a list comprehension that reads in all the csv files into a list, dfs.
Write a list comprehension that looks at the .shape of each DataFrame in the list.
