Sorry, something went wrong.
…isoformat()` (python#130962) Fix the pure Python implementation of `fromisoformat()` to reject any non-digit characters, including whitespace, in the fractional part of time specification. This makes the behavior consistent with the C implementation, and prevents incorrect parsing of these fractions (e.g. `.400 ` would be misinterpreted as `.04`). Co-authored-by: Peter Bierma <zintensitydev@gmail.com> Co-authored-by: Paul Ganssle <1377457+pganssle@users.noreply.github.com> (cherry picked from commit 33494b4)
