follow the dive into python
-----------------------------------------------------------------
>>> import sys
>>> sys.path
>>> sys.path.append('E:\achieve\book\diveintopython-pdfzh-cn-5.4b\diveintopythonzh-cn-5.4b\py')
-----------------------------------------------------------------
I append the filepath of <<dive into python>>'s examples into
sys.path,but
-----------------------------------------------------------------
>>> sys.path
['C:\\Python25\\Lib\\idlelib', 'C:\\WINDOWS\\system32\\python25.zip',
'C:\\Python25\\DLLs', 'C:\\Python25\\lib', 'C:\\Python25\\lib\\plat-
win', 'C:\\Python25\\lib\\lib-tk', 'C:\\Python25', 'C:\\Python25\\lib\site-packages', 'E:\x07chieve\x08ook\\diveintopython-pdfzh-cn-5.4b\diveintopythonzh-cn-5.4b\\py']
>>> import fileinfo#fileinfo is a module in the path

Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
import fileinfo
ImportError: No module named fileinfo

-----------------------------------------------------------------
Can anyone tell me the reason of the above and how to add paths to
python path except adding them in the enviroment path.
Thanks.

The path you append to sys.path is not properly escaped:

>>> "E:\archive"
'E:\x07rchive' # \a has become the single character chr(7)

Use double backslashes or raw strings instead:

>>> "E:\\archive"
'E:\\archive'
>>> r"E:\archive"
'E:\\archive'

When you print it the extra backslash will be gone:

>>> print "E:\\archive" # \\ is the escape sequence for the backslash
E:\archive

HI,

The code worked the first time it was run and allowed them to open the file,
make a back up etc... but when they saved and closed and re-opened it, it
crashed and locked up once the workbook had opened..


response :

Opened okay got to WPQ made one change, closed and reopened okay.

Went back in to WPQ and egg timer missing, no curser, all I had was a cross
and couldn't do anything

Had to use task manager to get out

Steve

WPQ is a page in the project

Might be good to head over to that user and try control+break when it hangs,
maybe some code is just running in an endless loop?

I managed to replicate on my HP computer for the first time.

The computer just ground to a halt, so I have used a work around, which
isn't as nice but seems to be working so far.

Set a worksheet value as true in workbook open

once workbook open and first menu sheet active

if worksheet value is true then save backup

(in the save backup set worksheet value to false)
