Write a Python program to create a new dictionary by extracting the mentioned keys and create a new new dictionary and print it as the result.
A fundamental concept of dictionary is that all its keys are unique. This is used ina lot of daily scenarios. For example, your student number uniquely identifiesyou at HKU and every office at HKU can use this number to link the data aboutyou. This concept can be used to implement a database where a unique key isused to identify all the data associated with this key.We will simulate a simple university database using dictionaries. Thedictionaries in the database are linked by unique keys that can be used toidentify a specific entry in a dictionary. For example, one of the dictionaries inthe database is a timetable dictionary that contains the timetable of differentcourses where each entry contains course_ID, teacher_ID, start_time, end_timeand venue_ID. The timetable dictionary can be linked to another dictionarycalled teacher dictionary by teacher_ID. We can therefore use the teacher_IDstored in the timetable dictionary as a key to retrieve the information of thecorresponding teacher stored in the teacher dictionary
