Transport for London (TfL) is the UK local government body responsible for the public transport system of Greater London; they make available an Excel document, which provides statistics about the usage of the underground network (the Tube) in the form of entry and exit passenger numbers for a "typical" day at each station over the years 2007–2017.
Read in this document with pandas, and analyze it to determine:
(a) the busiest station on a typical weekday in 2017;
(b) the station with the greatest percentage increase in passengers over the period 2007–2017;
(c) the station with the largest relative difference in passenger numbers between the working week and a typical Sunday in 2017.
