[ python-Bugs-1429481 ] For loop exit early

Category: Python Library Group: Python 2.4 Status: Open Resolution: None Priority: 5 Submitted By: msmith (mike_smith) Assigned to: Nobody/Anonymous (nobody) Summary: For loop exit early Initial Comment: When I run the following snippet the "for" loop exits early, not examining every item in the "lines" list. It will only print part of the list, i.e., only approximately 65% of any list I use is printed. (E.g., a list of 100 items only about 65 is printed) If I wrap the for statement in another for statement with a range() operator it works. I'm pretty new to scripting, so I'm sure there's a better way to do what I'm trying; but this seems like a bug.
