Category: IDLE Group: None Status: Open Resolution: None Priority: 5 Submitted By: paul rubin (phr) Assigned to: Nobody/Anonymous (nobody) Summary: python scratchpad Initial Comment: Lots of times I want to use Idle sort of like a Mathematica notebook but for Python. That is, I want to enter some code and interactively run it, edit it, run it some more, etc. Then, at the end, I typically don't want to save it. It's like doing a calculation on scratch paper and throwing away the paper after finding the answer. It's a bit of a pain to have to explicitly save such code in a file, going through the whole file dialog, after launching to a Python editor window. Most word processors will generate an automatic filename like "Untitled", or "Untitled-1", "Untitled-2", etc., if "Untitled" already exists. That makes the dialog a bit more streamlined. It would be nice if this type of operation were easier in IDLE. I'm not sure of the exact best way. Here are some: 1) Have a default filename ("Untitled-.py" for example) that saves to the user's home dir, or home/.idle, or maybe some configurable place. User could click to confirm (that's probably the easiest) or IDLE could display some kind of message (preferable) that doesn't need user interaction. IDLE has no status bar right now so maybe it would need one in order to display such a message conveniently. I guess the message could be displayed in the Python shell (by sending an appropriate print statement to the subprocess) if the user saves by hitting F5 to run the program. 2) (this is perhaps questionable) The default place to save the file could be in /tmp. On hitting F5, the Python shell would print a message noting that the file was only in /tmp and hadn't been saved anyplace permanent. -- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=355470&aid=1326830&group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Also any attempt to put the lambda form in an object didn't give a cure. say: Wrap(lambda x: x**2) creates a callable object storing the lambda form as a data member. >>> j = [Wrap(lambda t: t**n) for n in range(5)] >>> j[0](1) 1 >>> j[0](3) 81 >>> j[0](5) 625 Both Python 2.3 and 2.4 show this behaviour.

It is not unusual to have a situation arise in Python where a high level routine competes with a low level routine over which is in the best position to provide the most useful error message. The low level routine typically knows the proximate cause. The high level routine typically knows what the user was trying to do. In the case of str.join(), the high level routine usually makes the most informative error message; however, it is sometimes off the mark. Will revisit the design decision to see if it should be changed. Lowering the priority because the code is working as designed, the error type is correct, and it is not clear that any change is warranted. -- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1327110&group_id=5470 ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
