I'm trying to figure how to get how many of each item is in a string. Like for example:
{"harley": ["apple", "apple", "banana"]}
So how would I get this:
Harley has Apple x 2 and Banana x 1

5Take a look at [`collections.Counter`](http://docs.python.org/2/library/collections.html#collections.Counter) – Jan 24 '14 at 22:35

Lists also have a `count` method, but if you want to count all the things, it's much less efficient. – user2357112 supports Monica Jan 24 '14 at 22:36

Hmmm. Looks like collections.Counter is pretty good for this. – user3230748 Jan 24 '14 at 22:38

from collections import Counter
d = {"harley": ["apple", "apple", "banana"]}
for k,v in d.items():
print("%s has %s" %(k, ', '.join("%s x %s"%(k,v) for k,v in Counter(v).items())))

d = {"harley": ["apple", "apple", "banana"]}
from collections import Counter
for k,v in d.iteritems():
print k + ' has ' + ' and '.join('{0} x {1}'.format(name, count) for name, count in Counter(v).iteritems())
