The solution to your problem is as follows:
Step 1: Start the project with the Phone number dataset
Now there are two ways to go about this:
In order to check if a Phone number has more than own
country code associated with this.
Step 2: Use the shape
function on Paxata to perform a deduplicate and a group by operation.
Step 2.1: Perform a deduplicate on Country code, Phone
number to get rid of any repeated occurrence of a Country code, phone number
Step 2.2: Do a group by on Phone number and do a count on country
Step 3: Use an if statement via the compute feature we can
check if a duplicate exists on this column.
I hope this answers your question!
