From c5354c045c1067549554c35485a12afdcf88a202 Mon Sep 17 00:00:00 2001 From: Raymond Hettinger Date: Sat, 3 Apr 2021 13:09:01 -0700 Subject: Replace broken example code with correct simpler code. (GH-25162) The open() was missing 'w' to indicate it was in a write-mode. Even then, the open().close() operation was distracting because it is an unusual way to "touch" as file. Using os.remove() instead is simpler and less distracting. --- Doc/howto/descriptor.rst | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/Doc/howto/descriptor.rst b/Doc/howto/descriptor.rst index 819401e..bf026f4 100644 --- a/Doc/howto/descriptor.rst +++ b/Doc/howto/descriptor.rst @@ -115,9 +115,9 @@ different, updated answers each time:: 20 >>> g.size # The games directory has three files 3 - >>> open('games/newfile').close() # Add a fourth file to the directory + >>> os.remove('games/chess') # Delete a game >>> g.size # File count is automatically updated - 4 + 2 Besides showing how descriptors can run computations, this example also reveals the purpose of the parameters to :meth:`__get__`.
