Re: [Tutor] Weird import problem with PythonIDE on Mac (was 'import problem')

[Kent Johnson]

Is it possible that the script is not running as __main__? Add
print __name__
to the script and see what it says...

I wrote this yesterday....

Well, how bizarre! Now I run the code again (after having restarted the 
PythonIDE) and now I can't get it to NOT work.  And it previously had 
not run for many tries.

I don't suppose this is some sort of quantum effect ;-)
Oh well, I'll keep my eyes open to see if this happens again.
------------------
And now today, the problem is back again :-(  What's going on? Here is a 
smaller code:

###
def y1():
    print 'y1 executed'
for f in [y1]:
    name = f.__name__
    f()
    s1 = '%s()' % name
    s2 = 'from __main__ import %s' % name
    t=timeit.Timer(s1, s2)
    print t.timeit(1)
###
Here is the full report from the traceback window {it's great to be able 
to cut and paste from that window, thanks Just}

'''
ImportError: cannot import name y1
Traceback (innermost last)
File "<Untitled Script 1>", line 10, in ?
File "timeit.py", line 158, in timeit
      return self.inner(it, self.timer)
File "<timeit-src>", line 3, in inner
'''
** If I click on the edit button it says that <timeit-src> cannot be 
found. Is this an error to pay attention to or is that an unrelated 
problem of trying to browse a (perhaps compiled) source file?

Here is what I've tried to reproduce the problem:
1) I have restarted the system (10.2.8) and run nothing but this script 
and still get the error.
2) removed my PythonStartup and sitecustomize.py codes after quitting; 
problem still persists
3) re-installed MacPython 2.3.3 after moving the old version's macPython 
2.3.3 folder to the desktop
4) I have tried running the script in the add with and without the "run 
as __main__" option.

I DO NOT have the error show up when I run the script through the 
Terminal (i.e. %python timeitproblem.py).

I also DO NOT have the problem if I run the script with PyOXIDE.
As noted yesterday, there are some unknown steps that make the problem 
go away, though I do not know what these are yet.

Does anyone else have any insights?
