Question

python 3

needs to read a local JSON file - it doesn't need to access the internet.

Write a class named NobelData that reads a JSON file containing data on Nobel Prizes and allows the user to search that data. It just needs to read a local JSON file - it doesn't need to access the internet. Specifically, your class should have an init method that reads the file, and it should have a method named search_nobel that takes as parameters a year and a category, and returns a sorted list (in normal dictionary order) of the surnames for the winner(s) in that category for that year (up to three people can share the prize). The year will be a string (e.g. "1975"), not a number. The categories are: "chemistry", "economics", "literature", "peace", "physics", and "medicine". The JSON file will be named nobels.json and will be provided - you do not need to submit it.

For example, your class could be used like this:

nd = NobelData()
nd.search_nobel("2001", "economics")

The file must be named: NobelData.py

Answer 1

solution:

The main code is below it reads json data into a dictionary of arrays. the output is shown below as well as screenshot is added

CODE:

#import json
import requests #using request sto read data from internet

class NobelData:

def f(self):
return 'hello world'
def __init__(self):
response = requests.get("http://api.nobelprize.org/v1/prize.json")
self.data = response.json()
#print(self.data['prizes'][3])
def search_nobel(self,year,category):
n= len(self.data['prizes'])
winner_names=[]
for i in range(0,n):
if(self.data['prizes'][i]['year']==year and self.data['prizes'][i]['category']==category):
winner_names=self.data['prizes'][i]['laureates']
break
m=len(winner_names)
winner_surnames=[]
for i in range(0,m):
winner_surnames.append(winner_names[i]['surname'])
winner_surnames.sort() #returning sorted list of surnames
return winner_surnames

nd = NobelData()
winner_surnames=nd.search_nobel('2001','economics')
print(winner_surnames)

Output:

['Akerlof', 'Spence', 'Stiglitz']

winner_surnames list [Akerlof, Spence, Stiglitz]
