Python 2.7 has reached end of support
and will be
deprecated
on January 31, 2026. After deprecation, you won't be able to deploy Python 2.7
applications, even if your organization previously used an organization policy to
re-enable deployments of legacy runtimes. Your existing Python
2.7 applications will continue to run and receive traffic after their
deprecation date. We recommend that
you
migrate to the latest supported version of Python.

google.appengine.ext.bulkload.simpletext_connector module
Summary
Bulkloader Simple Text writing.
Handle the simpletext format specified in a bulkloader.yaml file.
Contents
- class google.appengine.ext.bulkload.simpletext_connector.SimpleTextConnector(template, prolog=None, epilog=None, mode='text', name='')source

epilog: written after the per-record output.
mode: one of the following, default is ‘text’
text: text file mode, newlines between records.
nonewline: text file mode, no added newlines.
binary: binary file mode, no added newlines.
-
name – The name of this transformer, for use in error messages.
ReturnsSimpleTextConnector object described by the specified options.
RaisesInvalidConfiguration – If the config is invalid.
