Hi Virginie,
Thank you for reaching out to Google Ads API Forum.
Please note that as per the limitations stated in the documentation for Audience Management (https://developers.google.com/google-ads/api/docs/remarketing/overview#limitations), user lists are not supported in test accounts and are automatically closed upon creation. For more information on test accounts and its limitations, you may also refer to this documentation (https://developers.google.com/google-ads/api/docs/first-call/test-accounts).
Additionally, since you are using Python in calling the API, you may check this documentation guide (https://developers.google.com/google-ads/api/docs/client-libs/python) for your reference.
Regards,
