4. Now, Implement the function provided in Assignment5_Interface.py to
perform the operations as listed below:
a. FindBusinessBasedOnCity(cityToSearch, saveLocation1, collection)
This function searches the ‘collection’ given to find all the business present
in the city provided in ‘cityToSearch’ and save it to ‘saveLocation1’. For
each business you found, you should store name Full address, city, state of
business in the following format.
Each line of the saved file will contain,
Name$FullAddress$City$State. ($ is the separator and must be
present)
b. FindBusinessBasedOnLocation(categoriesToSearch, myLocation,
maxDistance, saveLocation2, collection)
testData.json – This is the json file which is used as a document to put inside
MongoDb. The structure of one record of this file is < Key value pair>: -
{
This function searches the ‘collection’ given to find name of all the business
present in the ‘maxDistance’ from the given ‘myLocation’ that covers all the
given categories (the business category needs to match at least one of the given
categories) (please use the distance algorithm given below) and save them to ‘
saveLocation2’. Each line of the output file will contain the name of the
business only.
-- categoriesToSearch: a list of categories need to be covered
-- ‘myLocation’ will be given with format [“40.3”, “51.6”].
-- maxDistance: the search distance
-- saveLocation2: output location

The required task is two write two functions, which will perform some textual
and spatial searching on MongoDB. Details are explained below.
1. Install one of the versions of MongoDB 4.
2. Install pymongo to act as helper interface with MongoDB.
3. Run the tester file to check everything runs and nothing fails.
Steps for Assignments: -
NOTE: - Please Make sure all fields are in Uppercase while writing in file, makes it
easy to check. ☺
Files given to you: -
Assignment5_Interface.py - You should complete this file. You would
need to implement the function present in this file.
'type': 'business',
'business_id': (encrypted business id),
'name': (business name),
'neighborhoods': [(hood names)],
'full_address': (localized address),
'city': (city),
'state': (state),
'latitude': latitude,
'longitude': longitude,
'stars': (star rating, rounded to half-stars), 'review_count': review count,
'categories': [(localized category names)]
'open': True / False (corresponds to permanently closed, not business hours),
}
Example: -
{"city": "Ahwatukee",
"review_count": 3,
"name": "McDonald's",
"neighborhoods": [],
"type": "business",
"business_id": "LNdwp-9Isnd6xmBKUz4K_A",
"full_address": "10823 S 51st St\nAhwatukee, AZ 85044",
"state": "AZ",
"longitude": -111.975004,
"stars": 2.0,
"latitude": 33.348560900000003,
"open": true,
"categories": ["Burgers", "Fast Food", "Restaurants"]}
Note: - The order of key value pair does not matter.
tester.py – DO NOT change this file. This is just to help you run the code for
your implementation.
Distance Algorithm needs to be used:
Given two pair of latitude and longitude as [lat2, lon2] and [lat1, lon1], you can
calculate the distance between them using the formula given below:
DistanceFunction(lat2, lon2, lat1, lon1):
var R = 3959; // miles
var φ1 = lat1.toRadians();
var φ2 = lat2.toRadians();
var Δφ = (lat2-lat1).toRadians();
var Δλ = (lon2-lon1).toRadians();
var a = Math.sin(Δφ/2) * Math.sin(Δφ/2) +
Math.cos(φ1) * Math.cos(φ2) *
Math.sin(Δλ/2) * Math.sin(Δλ/2);
var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
var d = R * c;
d is the distance between the given pair of latitude and longitude. The distance is in
miles. Reference: http://www.movable-type.co.uk/scripts/latlong.html
Instructions for Assignment: -
Please follow these instructions closely else Marks will be deducted.
1. Please follow the function signature as provided in the Assignment5_Interfacy.py.
2. Please use the same database name and collection name as provided in the tester to
keep it consistent.
3. Please use the same distance algorithm given above to make it consistent for everyone.
4. Please make sure to run the file before submitting and make sure there is no
indentation error. In case of any compilation error, 0 marks will be given.
5. Do not modify any function signature in Assignment5_Interface.py. In
case any modification is needed, please post the same on discussion board.
6. For any case of doubt in the assignment, PLEASE USE Discussion Boards,
Individual mails would not be entertained.
7. Also, It is an individual’s responsibilities to clarify his/her doubts, so read and use
3
Discussion Board extensively.
Submission Instructions: -
Only submit Assignment5_Interface.py. No zip.
Note: -
Failure to follow the instructions provided in the document will result in the loss of the points.
