Solution overview: Weather statistics

- [Instructor] I'll start by giving you…a high level overview and demonstration…of my Python solution to the weather statistics challenge.…The data files for this challenge…are located in the exercise files…chapter one resources folder.…The data is formatted into four text files…representing weather records from 2012 to 2015.…Navigating back up one level…and then into the solution folder,…you'll find my solution to the challenge…which is a single Python script called weather.py.…

To demonstrate it,…I'll open a command prompt in this directory,…by typing CMD into the file explorer address bar…and then from there I'll type python weather.py…to execute the program,…and hit enter.…The program prints out messages…to let me know that it's loading…each of those four data files,…then it displays a user interface…with a chart showing barometric pressure values…for the entire four year period,…with a slope listed in inches of mercury per day.…

The slope is colored red to indicate a negative value.…I can enter specific dates and times…
