It is possible to read all files from a particular directory into DataFrames without knowing their names. Python provides a few ways to iterate through directories, with the glob module being a popular choice. The gas prices directory contains five different CSV files, each having weekly prices of a particular grade of gas beginning from 2007. Each file has just two columns--the date for the week and the price.
