You are an overworked, underpaid lab administrator. It's your job to figure out who has spent how long working on various projects. The Python file lab.py defines three dictionaries with information you'll need:
(INPUT CHECK BELOW Just and create file name lab.py and take input form that)

* Person maps user IDs to names;
* Project maps project IDs to project names; and
* Experiment describes the experiments that have been done for each project.
The keys in this dictionary are project IDs; the values are also dictionaries, with experiment names as keys, and lists of dates, hours spent, and people involved as values.

Write a Python program called hours.py that imports these three dictionaries, and uses the data in them to calculate how many hours each person has spent in the lab.
