- How would you describe the contents of a data dictionary?(d) create_area_dict(list2D) that takes a 2D-list containing the database as input and creates a dictionary called area_dict (you may rename it), where keys are the identity number of a CMA (ID) and values are the name of the CMA (Area). This function must return the dictionary. See sample output below. area_dict = create_area_dict(database) display_dict(area_dict) 31 - Cityview - Crestview - Meadowlands 903 - Billings Bridge - Alta Vista 908 - Byward Market 912 Carson Grove Carson Meadows 923 Glebe - Dows Lake 940 Overbrook - McArthur 942 - Portobello South 949 - Sandy Hill 957 - West Centertown (e) create_crime_dict(filename) that takes the filename of a csv file as input and returns a dictionary called crime_dict (you may rename it).
