hi,
i have to crawl last.fm for users (university exercise). I'm new to python and get following error:
Traceback (most recent call last):
File "crawler.py", line 23, in <module>
for f in user_.get_friends(limit='200'):
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/pylast.py", line 2717, in get_friends
for node in _collect_nodes(limit, self, "user.getFriends", False):

TypeError: coercing to Unicode: need string or buffer, User found
i use the pylast lib for crawling. what i want to do:
i want to get a users friends and the friends of the users friends. the error occurs, when i have a for loop in another for loop. here's the code:
network = pylast.get_lastfm_network(api_key = API_KEY, api_secret = API_SECRET, username = username, password_hash = password_hash)
user = network.get_user("vidarnelson")
friends = user.get_friends(limit='200')
i = 1
for friend in friends:
user_ = network.get_user(friend)
print '#%d %s' % (i, friend)
i = i + 1
for f in user_.get_friends(limit='200'):
print f
any advice?
thanks in advance. regards!
