>>> data = [['foo','bar','baz'],['my','your'],['holy','grail']] >>> [w for d in data for w in d] ['foo', 'bar', 'baz', 'my', 'your', 'holy', 'grail'] See how the for expressions in the list comprehension exactly match your nested for loops? That's all there is to it. Peter -- http://mail.python.org/mailman/listinfo/python-list
