Here are the docs for the Update.values() method:
https://docs.sqlalchemy.org/en/13/core/dml.html#sqlalchemy.sql.expression.Update.values
Note that it supports two main calling styles, either keyword arguments:
.values(name_column='cat')
...or passing a dictionary:
.values({'name_column': 'cat'})
Since you want to choose the column dynamically, you can use the
dictionary style:
updatevalues = {custom_column: value}
query = AIRPORT.update().values(updatevalues)
Hope that helps,
Simon
