SharePoint Rest call is not returning all fields - python-3.x

Question

Goal: Have python program pull data from SharePoint so we can store on database.
Issue: I am able to connect to share point and return data, but I am not getting all of the fields I can see when hitting the UI page. The UI page I am hitting is in the list on REST call but is a Custom View
Update: Using the renderashtml I was at least able to see some of the data points I am looking for. I would hope there is a better solution than this
Code:
import sharepy
connection = sharepy.connect("https://{site}.sharepoint.com")
r = connection.get("https://{site}.sharepoint.com/{page}/_api/web/Lists/getbytitle('{list_name}')/items")
print(r.content)
print(r.json())
#I have also tried
https://{site}.sharepoint.com/{page}/_api/web/lists('{list_id}')/views('{view_id}')
#I was able to return data as html
https://{site}.sharepoint.com/{page}/_api/web/lists('{list_id}')/views('{view_id}')/renderashtml
Research: I have taken a look at the rest documentation for sharepoint and I am under the impression you cannot return data from a view. The solution I saw was to first hit the view and then generate a list of columns and use that to build a query to search the list. I have tied that and those fields are not available when I pull the list but are in the view.

Answer 1

Are you trying to get the data from known fields, or discover the names of the fields?
Can you get the desired data by listing the fields in a select?
_api/web/lists/getbytitle('Documents')/items?$select=Title,Created,DateOfBirth
or to get all of the fields:
_api/web/lists/getbytitle('Documents')/items?$select=*
