描述

🐛 Bug

# %% tags=["parameters"]

s = "a=b"

# %%
print(s)

This fails with: Passed unknown parameter: s`". Seems like papermill naively counts = on the parameter line, so it's treated as unparseable, then flagged as “unknown parameter”.

Papermill version: 2.6.0.

研究方向
The issue is that parameter strings containing "=" are incorrectly parsed because papermill naively splits on '='. Look for the parameter parsing logic in the papermill source code, likely in files related to notebook execution or parameter injection (e.g., `papermill/execute.py` or `papermill/iorw.py`). The fix should use a more robust method to parse key value pairs, such as splitting only on the first '=' or using a regex that accounts for escaped '='. Ensure that the fix does not break existing parameter handling. No linked PRs or comments exist yet, so the issue is open for contribution.
