From 11fa0e48a958716186eb99348a46064e944eccf6 Mon Sep 17 00:00:00 2001 From: Cristian Ciupitu Date: Thu, 21 Feb 2019 09:53:06 +0200 Subject: [PATCH] Doc: fix example for iter() function. (GH-11959) read() returns bytes for a file opened in binary mode, so b'' should be used as a sentinel instead of ''. Otherwise the loop will be infinite. --- Doc/library/functions.rst | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/Doc/library/functions.rst b/Doc/library/functions.rst index cca28ff5fb..ebbee71f48 100644 --- a/Doc/library/functions.rst +++ b/Doc/library/functions.rst @@ -816,7 +816,7 @@ are always available.
