Thanks it works!

Thanks that works too!
I realy have to improve my recursion skills =(
Anyway having the directory :
+root
+doc1
lesson1
lesson2
+doc3
lesson3
+doc2
lesson4
lesson5
With the code :
<code>
#!/usr/bin/python
from os import listdir
from os.path import isdir,join,basename
import HTMLgen
dirpath = '/devel/python/html/test'
def rec(f):
res = []
for ele in listdir(f):
res.append(ele)
ele = join(f,ele)
if isdir(ele):
res.append(rec(ele))
return res
print HTMLgen.List(rec(dirpath))
</code>
Gives me the espected output as a HTML representation of the tree:
<UL>
<LI>doc1
<UL>
<LI>lesson1.html
<LI>lesson2.html
<LI>doc3
<UL>
<LI>lesson3.html
</UL>
</UL>
<LI>doc2
<UL>
<LI>lesson5.html
<LI>lesson4.html
</UL>
<LI>.tmp3.py.swp
</UL>
