Permutation of chars with python

It is a simple example of using python language to permutation of chars.
It uses a list generator and "yield":

#!/usr/bin/env python
def permut(lst):
    remove = lambda lst0, index: lst0[:index] + lst0[index+1:]
    if lst:
        for index, x in enumerate(lst):
            for y in permut(remove(lst, index)):
                yield (x,)+y
            print y 
                
    else: yield ()
lst='catalin'
for p in permut(['c','a','t','a','l','i','n']):
    print p

Example can be modified so output will be a file.

Google and Python Stuff

I want share this scripts.
Is just two scripts and i think is beautifull.
First is a youtube script :

import gdata.youtube
import gdata.youtube.service

client_yt = gdata.youtube.service.YouTubeService()
query = gdata.youtube.service.YouTubeVideoQuery()
query.vs = "%s" % ('News')
feed = client_yt.YouTubeQuery(query)

for entry in feed.entry:
print entry.title.text
for link in entry.link:
if link.rel == 'alternate':
print link.href

Second is a picassa script :

import gdata.photos
import gdata.photos.service
import urllib
p_client = gdata.photos.service.PhotosService()

query_parameters = map(urllib.quote, ['Sexy','Bucharest']);
feed = p_client.GetFeed("/data/feed/api/all?q=%s%s&max-results=10" % ('Sexy','Girl'))

for entry in feed.entry:
print entry.title.text
for link in entry.link:
if link.rel == 'alternate':
print link.href

I hope you like this little scripts.
