Build a Time log file parser in Python3

Write a Python 3 program tlparser_xxxxxxx.py to parse the five given timelog data files to get how many hours and minutes the author spent in each file. The timelog file name will be an argument for your Python program. For example, you run your program on the spirit machine like
“python3 tlparser_xxxxxxx.py TimeLogCarbon.txt”
Expected output: 4.56hours

You are expected not to use datetime python module or re python module or pandas.
