Re: Tabnanny errors when Migrating Python 2.4 code to 2.5
I'm using Windows XP, using IDLE (which was mentioned already) in the context of editing/displaying code, not executing it. Does the problem occur before or after you edit a file with IDLE? Actually, neither. I'm not editing the code. I open it in IDLE in 2.5 and attempt to run it through the Run menu Run Module menu item or by pressing F5. It immediately fails with a tabnanny error. If I run it from 2.4's IDLE, it works. and I downloaded the 2.5.1 exe/msi file from python.org to install it. What you downloaded doesn't answer the question about how you installed it. Do you still have your 2.4 installation? Yes, I use both 2.4 and 2.5 as I migrate from one to the other. I've attached a file that causes it consistently. On two systems with both 2.4 and 2.5 installed, it fails on line 206 when run from the IDLE included with 2.5. I have yet to find a simple one which exhibits the issue to post. It seems to happen to my complex files, not the simple ones. So chop up a complex file ... Have you inspected the failing files using a text editor that can display tabs and spaces (e.g. PythonWin, TextPad)? I just used Notepad++ to inspect the file and it does indeed have tabs at line 206 rather than spaces. I take it that Python 2.5 is more sensitive to that than is 2.4? I program almost exclusively in IDLE as I'd read that this can happen in some text editors, but it seemed implied that it didn't if you used IDLE. At least, that's what I got from various Python books and the website: http://www.python.org/idle/doc/idlemain.html Anyway, thanks for the help.

Not really soo useful, because most syntax and also indentation errors
are actually detected by invoking python, i.e. the command compile.
But as combination for this: yes why not.
I looked for Stanis spe editor, which uses a combination of these two.
The background is:
I'm a member of the wxPython project Drpython (Python text editor
and much more), and wanted also check the usefulness of a kind of syntax
check, which should run, before saving a Python file.
PythonCard Codeeditor also uses tabnanny, as far as i can remember.

I've used drpython, and liked it. I think it would be a good way for
people to start to use the language, as it avoids the just the command

just about right for a beginner.

Re: Tabnanny really useful?
I'm told Tabnanny was inspired by lint, the Unix utiltity to check C sources (and probably others). Lint was primarily useful in days long ago when CPUs were slow and a compile used a significant amount of resources. In a multiuser environment (we ran an Intel 286 in multiuser mode!!), the compiles could bring everyone else to a crawl. Lint was used because it was a less-CPU intensive way to catch bonehead errors and fix them before using precious compile time. Today,lint and Tabnanny may still have their uses as noted by others to cleanup the tab/space conundrum. -- Mike Franz Steinhaeusler [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi, I looked at tabnanny to check a python source file.

Originally, lint caught errors the C compiler didn't flag as
errors. For example:
int *main = { . } ;
The C compiler would build and link that just fine on v7. lint would
complain about it. Of course, if you used the right ints to fill the
array, it would produce a valid executable.

Tabnanny is intended to check whether indentation has mixed tabs and spaces. Files with mixed tabs and spaces _can_ compile just fine if the editor that produced them agrees with the compiler about the number of spaces that a tab occupies. On the other hand, such files are quite likely to be messed up almost beyond repair if one tries to edit them in an editor that treats tabs differently from the one that produced it. Files that stick to one or the other can always be edited and compiled properly. The python recommendation is to use spaces, but not everyone agrees with this.
