It is a python assignment working with a json file

Final Assignment – COMP 1110 (Fall 2020)                                                                                     (Total: 30 points)

 

Introduction:

 

In this final assignment you are asked to write a python program that extracts monthly rainfall for different cities from a JSON file.

 

The JSON file provided, climate.json, contains monthly climate data of over one-hundred destinations and includes average high and low temperature, dry days, snow days, and rainfall, for every month.

 

Program Tasks:

 

Write a program displayClimate.py that performs the following functionalities:

 

1. reads the JSON file climate.json

 

2. displays the cities as a list.

 

3. prompts the user to enter a city or cities.

 

4. searches for the relevant data and display(s):

 

1. 1. the average rainfall for each month as a list.

 

1. 2. minimum and maximum rainfall per year.

 

1. 3. the average rainfall per year. 

 

5. The use of at least three functions (not including the main function) must be implemented in creating this assignment, as well as basic error checking.  Submissions without appropriate functions and basic error checking in place would automatically be not graded and a zero-mark credited.  Using only main() function is also not acceptable as having written an appropriate function in your program code, hence your assignment would automatically be not graded and a zero-mark credited.

 

Brief introduction to the JSON file

 

Structure of the climate JSON file:

 

• JSON data works just like python dictionary and you can access the value using dictionaryName[key].

 

• The JSON file contains a list of 104 dictionary items and each dictionary item has 4 keys. 

 

• The monthlyAvg key has a list as its value, which in return contains 12 dictionary items representing each month in a year. 

 

• You may use the website https://codebeautify.org/jsonviewer and load the file into its editor. The website will display structure and details of this JSON file.  Alternatively, you can view this file using any text editor.

 

• A snapshot of the structure of this file is shown on the following page. 

 

 

 

 

 

Loading a JSON file:

 

with open('climate.json', 'r') as f:

  # convert a json object into a readable python object      data = json.load(f) 

 

 

Requirements that MUST be fulfilled to receive credit for this assignment:

 

1. Readability of your code and proper code documentation. 

 

2. Use of user defined functions.  

 

Structure of climate.json file:
