There is data-extension-row-update and data-extension-row-create, but nothing like
data-extension-row-append.
Say I have an existing data extension I retrieve via
import ET_Client
myClient = ET_Client.ET_Client()
dataextensionrow = ET_Client.ET_DataExtension_Row()
dataextensionrow.auth_stub = myClient
dataextensionrow.Name = 'ExampleDEName'
how can I possibly append a row to an existing SFMC data extension just like in a CSV or tabular structure (e.g. a pandas.DataFrame), for instance appending another row to the following:
index, col1, col2, col3
0, val1, val2, val3
which could look like
1, foo, baz, bar
PS: This is not about how to construct a Python dictionary or pandas.DataFrame. I just made this analogy in order to illustrate what I hope is possible with SalesForce data extensions: appending rows to them on-the-fly.
