[python-win32] opening files with names in non-english characters.

[venu madhav]

Hello,        First of all thanks for your response. I've written a function
as shown below to recurse a directory and return a file based on the value
of n. I am calling this fucntion from my main code to catch that filename.
The folder which it recurses through contains a folder having files with
unicode names (as an example i've given earlier.
-----------------------------------------------------------------------------
def findFile(dir_path):
    for name in os.listdir(dir_path):
        full_path = os.path.join(dir_path, name)
        print full_path
        if os.path.isdir(full_path):
            findFile(full_path)
        else:
            n = n - 1
            if(n ==0):
                return full_path
--------------------------------------------------------------------------------------------------
                    The problem is in the return statement. In the function
when I tried to print the file name, it is printing properly but the
receiving variable is not getting populated with the file name. The below
code (1st statement) shows the value of the full_path variable while the
control is at the return statement. The second statement is in the main code
from where the function call has been made.
Once the control has reached the main procedure after executing the findFile
procedure, the third statement gives the status of file variable which has
type as NoneType and value as None. Now when I try to check if the path
exists, it fails giving the below trace back.

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
E:\DataSet\Unicode\UnicodeFiles_8859\001_0006_test_folder\0003testUnicode_ÍÎIÐNOKÔÕÖ×ØUÚÛÜUUßaáâãäåæicéeëeíîidnokôõö÷øuúûüuu.txt.txt
------------------------------------------------------------------------------------------------------------------------------------------------------------------------
file = findFile(fpath)
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
file
NoneType
None

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
This is the final trace back:

Traceback (most recent call last):
  File "C:\RecallStubFopen.py", line 268, in <module>
    if os.path.exists(file):
  File "C:\Python26\lib\genericpath.py", line 18, in exists
    st = os.stat(path)
TypeError: coercing to Unicode: need string or buffer, NoneType found

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Please ask if you need any further information.


Thank you,
Venu
