The manual says: """Optional in-place filtering: if the keyword argument
inplace=1 is passed to input() or to the FileInput constructor, the file is
moved to a backup file and standard output is directed to the input file.
This makes it possible to write a filter that rewrites its input file in
place. If the keyword argument backup='.<some extension>' is also given, it
specifies the extension for the backup file, and the backup file remains
around; by default, the extension is '.bak' and it is deleted when the
output file is closed. In-place filtering is disabled when standard input is
read."""

So I guess the martellibot is correct again, which I know will stagger few
regular readers :^) .
