Right now, will concentrate on fixing an expectation issue with the assistance of a particular situation.
Think about that as an organization needs to mechanize the credit qualification subtleties according to the client subtleties gave through online application structure. The subtleties incorporate name of client, sexual orientation, conjugal status, advance sum and other compulsory subtleties.
The subtleties are recorded in the CSV document as appeared underneath −
Execute the accompanying code to assess the forecast issue −
