Hi All
I have a web app that allows me to choose a file - the file name is returned
but I need
to find the path to the file so I can add it as an attachment to a email.
The files I am returning could be in different folders/directories.
Thanks for any help.
Cheers

Hello,
I did this almost equivalent unix find command in python it is
documented, it is a generator. If it could help you:
import os
from os.path import join as jp, normpath as np
def find(dirs, filenames=None, exts=None, exclude_dirs=None,
exclude_filenames=None, followlinks=False):
""" Equivalent to the unix/linux find shell command.
@param dirs the top directories where to search.
Could be a simple string.
Default to current directory '.'.
@param filenames the searched file names. Could be a
simple string.
@param exts an additional parameter to search files
by its extension.
Could be cumulative with the filenames
@param exclude_dirs a filter to exclude given top
directories from the search process.
Coud be a simple string.
@param exclude_filenames a filter to bypass certain files by its
name.
Useful when using a search by file
extension.
Could be a simple string.
@param followlinks a boolean to specify whether to follow
symbolic links to subdirectories.
Defaulted to False.
@return a generator data which provides the found file one after
another.
"""
if not filenames and not exts:
raise ValueError('The list of searched files and the list of
searched file extensions could not be both empty!')
if filenames is None:
filenames = ''
if exts is None:
exts = ''
if exclude_dirs is None:
exclude_dirs = ''
if exclude_filenames is None:
exclude_filenames = ''
# Default value
if not dirs:
dirs = tuple(('.',))
if isinstance(dirs, str):
dirs = tuple((dirs,))
if isinstance(filenames, str):
filenames = tuple((filenames,))
if isinstance(exts, str):
exts = tuple((exts,))
if isinstance(exclude_dirs, str):
exclude_dirs = tuple((exclude_dirs,))
if isinstance(exclude_filenames, str):
exclude_filenames = tuple((exclude_filenames,))
# The search.
for d in dirs:
for dirpath, dirnames, fnames in os.walk(d,
followlinks=followlinks):
# Filtering unwanted top directories.
for d in exclude_dirs:
if d in dirnames:
dirnames.remove(d)
# Search for file names or extensions
for f in fnames:
file_extension = os.path.splitext(f)[-1][1:] #
extension without the dot!
if f in filenames or (file_extension in exts and f not
in exclude_filenames):
yield jp(dirpath, f)
if __name__ == '__main__':
#print(np('\n'.join(find(dirs='.', exts='li',
exclude_filenames='cds.li'))))
# Test
l = tuple(find(dirs='.', filenames='cds.lib'))
print('\n'.join(l))
