Question

Write a function named "query_dict" that a key-value store as a parameter mapping strings to floating point numbers. The function will make an HTTPS GET request to the url "https://fury.cse.buffalo.edu/ps-api/a" with a query string containing the same key-value pairs from the input key-value store. The response from the server will be a JSON string representing an object in the format "{"answer": <Number>}" where <Number> is a floating point Number. Return the value at the key "answer" as a float

Recall that you may need to convert the numbers to strings

==========================================

import urllib.request

import json

def query_dict(mapping_strings):

url_to_send_request=r'https://fury.cse.buffalo.edu/ps-api/a'

#framing query to send with mapping strings - START

i=0

for pair in mapping_strings:

if i == 0:

url_to_send_request += "?";

else:

url_to_send_request += "&"

url_to_send_request += pair + "=" + str(mapping_strings[pair])

i=i+1

#framing query to send with mapping strings - END

#url_to_send_request=url_to_send_request+'?'+urllib.parse.urlencode(mapping_strings) #WAY-2 with urllib

print(url_to_send_request)

response_from_url=urllib.request.urlopen(url_to_send_request).read().decode()

json_response_from_url=json.loads(response_from_url)

return float(json_response_from_url['answer'])

mapping_strings={'x':15,'y':14,'z':25}

print("Floating noint number is:",query_dict(mapping_strings))

OUTPUT:-

====

https://fury.cse.buffalo.edu/ps-api/a?x=15&y=14&z=25
Floating noint number is: 3976.19
