Hi All,
I am new to python - so this might be embarrassing - but thanks in
advance!
Can somebody tell me why I get an error when I uncomment the line in
the code below and run it in the appengine interactive shell?
The error I get is:
'title =', 'song'
Traceback (most recent call last):

attr = 'title'

print query_string
query = Song.all()
query.filter('title =', "song") # no error!
#query.filter(query_string) #error!
result = query.fetch(1000)
print result[0]
