format_test.py error is not intelligible

Description

When using the swagger codegen to generate code from an OpenAPI spec, it produces an error message when a regular expression has been used to limit which characters can be used for a value.

The error reads "must be a follow pattern or equal to ". I am objecting to the wording of 'follow pattern'. What is a 'follow pattern'? My guess is that this was supposed to say, 'must follow a pattern or be equal to <...>'. But that is only a guess.

The code is here.

Is 'follow pattern' a real term? If not, can we simply reword this error to be more intelligible?

Start at samples/client/petstore/python/petstore_api/models/format_test.py:273 and trace the generated message back to its template or source. Improve the validation wording, then regenerate or run the relevant Python petstore sample to confirm the output is intelligible.
