Code golf: find all anagrams

Question

A word is an anagram if the letters in that word can be re-arranged to form a different word.

Task:

• The shortest source code by character count to find

Answer 1

Python, 167 characters, includes I/O

import sys
d={}
for l in sys.stdin.readlines():
 l=l[:-1]
 k=''.join(sorted(l)).lower()
 d[k]=d.pop(k,[])+[l]
for k in d:
 if len(d[k])>1: print(' '.join(d[k]))

Without the input code (i.e. if we assume the wordlist already in a list w), it's only 134 characters:

d={}
for l in w:
 l=l[:-1]
 k=''.join(lower(sorted(l)))
 d[k]=d.pop(k,[])+[l]
for k in d:
 if len(d[k])>1: print(' '.join(d[k]))
