On Linux you can set up command aliases, e.g. `alias python=python -O` and I dare say there is some equivalent under Windows. Once you have done so (which could be many months in the past, and forgotten about) you no longer need to actively specify -O to run with optimization on. > which > I'd assume someone intentionally using an assertion wouldn't do. Provided that they know the side-effect of -O, and that the code contains an assertion. Not all code is executed by the same person who wrote it, and not all people remember every fine detail about every script they wrote. I couldn't possibly tell you what all my scripts do without checking the source code. -- Steven -- http://mail.python.org/mailman/listinfo/python-list

In article , Dave Angel wrote: > I'd also add a print statement, just to assure yourself that it's running. My trick to make sure something is running is to add "assert 0". To be fair, I usually start by adding a print statement, as Dave suggests. If I see the output, I know it ran. But if I don't see the output, there's two possibilities. Either it didn't run, or it ran but something snarfed the output and hid it from my eyes. That's common in test frameworks. It's also common in background processes where stdout goes who-knows-where, and it's anybody's guess how the logging config might be borked. On the other hand, an "assert 0" is pretty much guaranteed to produce some visible evidence that it ran. About the only thing that would stop it is if somebody had wrapped the code in a try block which caught AssertionError (or Exception). -- http://mail.python.org/mailman/listinfo/python-list

As it stands, it's just an importable module, doing nothing useful when you run it. Add a call to test() to the end of the file, and it might do better. I'd also add a print statement, just to assure yourself that it's running. -- DaveA -- http://mail.python.org/mailman/listinfo/python-list

debugging in eclipse+pydev
Hi. I'd like to know how to debug in eclipse+pydev. In the menu, "Pydev Debug", there's Start Debug Server option, but I don't know how to use it. Few questions I have about debugging are: 1) how do i set a breakpoints in pydev? 2) how do i execute the code line by line? I mean... step into, step over, and so on... When I searched on http://www.fabioz.com/pydev/, I found that Run/Debug Step Into F5 Debugging Run/Debug Step Over F6 Debugging Run/Debug Step Return F7 Debugging Run/Debug Resume F8 Debugging However, Starting Debug Server and pressing F5, F6, F7 didn't do those functions. Can anyone give me a small tutorial as to how to debug in Eclipse + Pydev please? Thanks in advance. -- http://mail.python.org/mailman/listinfo/python-list
