Walkthrough

The strptime function in the time module was changed to delegate parsing to CPython's _strptime._strptime_time (imported at runtime) instead of using local NaiveDateTime::parse_from_str. The function signature was generalized from PyResult<PyStructTime> to PyResult.

Poem

🐰 Hopping through the code I go,
I hand the clocks to Python's flow,
No more parsing in my den,
I call the old strptime then,
A lighter hop, and off I go! 🥕
