Your program code should all be in a single python file with at least two functions, one called tomorrowyesterday() and the other called yesterdaytomorrow().:
* The yesterday() function will take a date in "YYYYMMDD" format and return the date of the previous day in the same format. * The tomorrow() function will take a date in "YYYYMMDD" format and return the date of the next day in the same format.
