> Membership for Row class does not include field names
> -----------------------------------------------------
>
> Key: FLINK-35112
> URL: https://issues.apache.org/jira/browse/FLINK-35112
> Project: Flink
> Issue Type: Bug
> Components: API / Python
> Affects Versions: 1.18.1
> Reporter: Wouter Zorgdrager
> Assignee: Wouter Zorgdrager
> Priority: Minor
> Labels: pull-request-available
> Fix For: 1.20.0
>
>
> In the Row class in PyFlink I cannot do a membership check for field names.
> This minimal example will show the unexpected behavior:
> ```
> from pyflink.common import Row
> row = Row(name="Alice", age=11)
> # Expected to be True, but is False
> print("name" in row)
> person = Row("name", "age")
> # This is True, as expected
> print('name' in person)
> ```
> The related code in the Row class is:
> ```
> def __contains__(self, item):
> return item in self._values
> ```
> It should be relatively easy to fix with the following code:
> ```
> def __contains__(self, item):
> if hasattr(self, "_fields"):
> return item in self._fields
> else:
> return item in self._values
> ```
