Re: [Tutor] Import Statement Failing With IDLE?

[Kent Johnson]

I don't know why you are getting different results, but I do know that you aren't supposed to put 
the whole psyco-1.3 folder inside site-packages. Just put the psyco folder (from inside psyco-1.3) 
into site-packages.

Also the os.chdir() doesn't have any effect on import.
You could compare sys.path in the two different environments and see what is different between them.
>>> import sys
>>> sys.path
['', 'C:\\Python24\\python24.zip', 'D:\\Projects', 'C:\\Python24\\DLLs', 'C:\\Python24\\lib', 
'C:\\Python24\\lib\\plat-win', 'C:\\Python24\\lib\\lib-t
k', 'C:\\Python24', 'C:\\Python24\\lib\\site-packages', 'C:\\Python24\\lib\\site-packages\\win32', 
'C:\\Python24\\lib\\site-packages\\win32\\lib', 'C:
\\Python24\\lib\\site-packages\\Pythonwin']

You can also find out where psyco is being found by printing the module's 
__file__ attribute:
>>> import psyco
>>> psyco.__file__
'C:\\Python24\\lib\\site-packages\\psyco\\__init__.py'

Hello all, 
I recently downloaded Psyco and put it in the site-packages folder. 
Now, when i tried to use it to optimize a program, IDLE says it can't
find it:

IDLE 1.1      

import os
os.chdir(r"c:\python24\lib\site-packes\psyco-1.3")
import psyco

Traceback (most recent call last):
  File "<pyshell#5>", line 1, in -toplevel-
    import psyco
ImportError: No module named psyco
... However, when using the Command Prompt:

Type "help", "copyright", "credits" or "license" for more information.
import os
os.getcwd()
'C:\\Python24'
os.chdir(r"c:\python24\lib\site-packages\psyco-1.3")
import psyco

Anyone know why this is? . . . 

Thanks in advance,
Orri
