Warning: “Core Pydantic V1 functionality isn't compatible with Python 3.14 or greater” when importing cloudflare #2675
Description
Confirm this is a Python library issue and not an underlying Cloudflare API issue.
- This is an issue with the Python library
Describe the bug
When importing the cloudflare package under Python 3.14, a UserWarning appears from the _compat.py module:
/.../.venv/lib/python3.14/site-packages/cloudflare/_compat.py:48: UserWarning: Core Pydantic V1 functionality isn't compatible with Python 3.14 or greater.
from pydantic.v1.typing import (
The library uses Pydantic v2 for its models, but still imports from the pydantic.v1 namespace for compatibility. This warning originates from Pydantic itself, which now emits it on Python ≥ 3.14.
To Reproduce
python3.14 -m venv .venv
source .venv/bin/activate
pip install cloudflare
python -c "import cloudflare; print(cloudflare.__version__)"

I think it's safe to suppress the warning with:

warnings.filterwarnings("ignore", message="Core Pydantic V1 functionality isn't compatible")

pyenv install 3.12.6
pyenv local 3.12.6
python -m venv .venv
source .venv/bin/activate
pip install cloudflare
