Party Times in Towns

Given the name of a town, party IDs, and their details including start and end times in string format like 2am, 10pm. Write a function to output all the start and end times of parties in the town. For example, Town A has two parties with times 1pm-3pm and 8pm-10pm, the output should be {A: [13-22]}. Note that you need to convert AM/PM time to integer in 24-hour format. Assume each partyID is unique. Example Input A {'A': [101, 102]} [{'id': 101, 'start': '1pm', 'end': '3pm'}, {'id': 102, 'start': '8pm', 'end': '10pm'}]
