The details about problem is You have two sets of csv files - one containing the contracts data and the other containing the awarded contracts. Your task is to combine the two csv files using the common field (contractName) and compute the total amount of closed awarded contracts. The combined csv should also include one more field - latlon which contains the geocoded value of the contract location, if available. Use the API (from google, osm, or others) to geocode the location.

There are problems with the data, which means there are closed contracts which have not been awarded yet.

The data are not real data and presented for this problem only. The data fields and real data are available at http://www.edolidar.gov.np/tenders.php

The first contract file contains the following fields

contractname
status
bidPurchaseDeadline
bidSubmissionDeadline
bidOpeningDate
tenderid
publicationDate
publishedIn

The second award file contains the following fields

contractName
contractDate
completionDate
awardee
awardeeLocation
Amount

The output file will contain the fields from both files (blank values if the contract is not awarded yet)

contractname
status
bidPurchaseDeadline
bidSubmissionDeadline
bidOpeningDate
tenderid
publicationDate
publishedIn
contractDate
completionDate
awardee
awardeeLocation
latlon
Amount

After the file is created, read the output file and show the total amount of awarded contracts which have been closed. 700,000 in our case.

The solution of the problem is done in Python using Pandas package and geopy module . The Output of the project is final_output.csv
