converting octal strings to unicode

I have several ascii files that contain '\ooo' strings which represent
the octal value for a character. I want to convert these files to
unicode, and I came up with the following script. But it seems to me
that there must be a much simpler way to do it. Could someone more
experienced suggest some improvements?

I want to convert a file eg. containing:

hello \326du

with the unicode file containing:

hello ÷du
----------8<---------------------------------------
#!/usr/bin/python

import re, string, sys

if len(sys.argv) > 1:
file = open(sys.argv[1],'r')
lines = file.readlines( )
file.close()
else:
print "give a filename"
sys.exit()

def to_unichr(str):
oct = string.atoi(str .group(1),8)
return unichr(oct)

for line in lines:
line = string.rstrip(u nicode(line,'La tin-1'))
if re.compile(r'\\ \d\d\d').search (line):
line = re.sub(r'\\(\d\ d\d)', to_unichr, line)
line = line.encode('ut f-8')
print line

decoded_string = "\326du".decode ("string_escape ")
unicode_text = unicode(decoded _string, "latin-1")

(hope I cancelled the previous off-by-one-backslash post...)

your_string = "\\326du"
decoded_string = your_string.dec ode("string_esc ape")
unicode_text = unicode(decoded _string, "latin-1")

I recently found out that unicode("\347", "iso-8859-1") is the lowercase c-with-cedilla, so I set out to round up the unicode numbers of the extra characters you need for French, and I found them all just fine EXCEPT for the o-e ligature (oeuvre, etc). I examined the unicode characters from 0 to 900 without finding it; then I looked at...

Hi, I've been putting Python data into a sqlite3 database as tuples but when I retrieve them they come back as unicode data e.g 'u(1,2,3,4)'.How can I change it back to a tuple so I can use it as a Python native datatype? I have looked in the docs and seen there is a decode/encode method but how do I do this? Hope you can help.
