RE: [Python-Dev] file() or open()?

I think Skip wrote: > Yes, but has others have pointed out, the current documentation > seems to suggest that file() is preferred to open(). While you're at it, the docstring for open could use the same treatment. In 2.3.2, it starts with: "file(name[, mode[, buffering]])" and ends with "open() is an alias for file()." The first implies that file() is preferred, in my mind. Robert Brewer MIS Amor Ministries fumanchu(a)amor.org

tabs in idlelib/PyShell.py

July 7, 2004

A change made in CVS to Lib/idlelib/PyShell.py have tabs as indentation at line 837 and 838. This breaks installation. This was checked in two days ago and haven't yet been fixed. I just thought I would speak up.

The documentation, tutorial and other files is in .tex format in CVS. How can I convert them to a HTML or PDF format? I tried with pdftex (from tetex package) but it gives me structure errors. Thank you! Facundo Batista Desarrollo de Red fbatista(a)unifon.com.ar (54 11) 5130-4643 Cel: 15 5097 5024

decimal API
by Raymond Hettinger July 6, 2004

July 6, 2004

Currently, calling the Decimal constructor with an invalid literal (such as Decimal("Fred")) returns a quiet NaN. This was done because the spec appeared to require it (in fact, there are IBM test cases to confirm that behavior). I've discussed this with Mike Cowlishaw (author of the spec and test cases) and he has just clarified that, "... the intent here was not to disallow an exception. The analogy, perhaps, is to a divide-by-zero: the latter raises Invalid Operation and returns a qNaN. … [View More]
