Overview
This is a review assignment where you will use multiple tools you have picked up so far throughout the course. If you're confused about how to do something make sure you look back
at earlier assignments.
In this program you will start by declaring an empty dictionary named population_dict. Then you will use a while-loop to prompt a user for a series of cities and their populations,
storing the input in population_dict). After this you will prompt the user to decide what is the maximum population for a city to be considers a small down. Finally, you will open a file
called populationdata.txt where you will write the results.
Expected Output
Example of standard out (the console):
What is next city? (enter q to quit) Long Beach
What is the population of Long Beach? 362000
What is next city? (enter q to quit) Los Angeles
What is the population of Los Angeles? 382000000
What is next city? (enter q to quit) San Diego
What is the population of San Diego? 136000000
What is next city? (enter q to quit) Irvine
What is the population of Irvine? 302000
What is next city? (enter q to quit) Detroit
What is the population of Detroit? 606000
What is next city? (enter q to quit)

descrpition: Our title for this project is File System in a windows computer. File system plays a big part in managing user data in a computer. This includes storing, retrieving and updating data. In order to handle user data, this application compresses files separated into groups, which is known as directories. Thus, tree data structure is applied as it is a powerful tool for organizing data objects based on keys. It is equally useful for organizing multiple data objects in terms of hierarchical relationships based on the description, Identify the Collection class and the interfaces used. List all the operations (from the class an interface) for each.
Define a function named print_details () which takes a dictionary library as a parameter. The key of each item in the dictionary is the name of an artist, and the value is a list of tuples where each tuple contains the name and duration of a song by the artist. The function prints the details of each artist and their collection of songs as shown in the examples below. For example, if the dictionary contains a single element: {'Wiz Khalifa': [('We Own It', 227), ('See You Again', 229), ('Something New', 200)]} then the output is: Artist: Wiz Khalifa Songs: See You Again Something New We Own It Total duration: 656 seconds The function first prints the name of the artist and then prints the name of each song in the list of songs in sorted ascending order. The function should add up the duration of all the songs by a given artist and print the total duration (in seconds) of all the artist's songs. Note: • You can assume that the parameter dictionary is not empty and the values are in the…
