Question

Consider a playlist stored in a text file. The example below is named 265. list and demonstrates the way such files are formatted. Note the individual tracks in the playlist correspond to the lines following the third line. Write a Python function that accepts the name of an input file containing data such as that above and returns an instance of a PIaylist class. As part of your solution you must also define the PIaylist class. Amongst other class attributes, the tracks in a PIaylist instance must be stored in a single list attribute of that instance. There must be a method in PIayList named total Length () which returns a tuple containing the number of hours, minutes and seconds needed to play all of the tracks from start to finish. Regular expressions must be used where appropriate. Some marks will be given for the quality of your solution. Your indentation is to be clearly indicated. Some marks will be given for the quality of your answer.
