Opening several files at once is error-prone, and the returned list cannot be used in a "with" statement. Iterate over the names returned by askopenfilenames() and open them one by one instead. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Deprecating in 3.16 and removing in 3.19 gives three feature releases of deprecation before removal. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Documentation build overview

Import warnings inside askopenfiles() rather than at module level, since it is only used by the deprecation there. Break the new documentation lines at sentence and clause boundaries. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Opening several files at once is error-prone, and the returned list cannot be used in a
withstatement: if opening one of the files fails, the files already opened are leaked; correct cleanup on error is awkward; and the number of open file descriptors is limited.Iterate over the names returned by
askopenfilenames()and open them one by one instead.The single-file
askopenfile()/asksaveasfile()are not affected.
