data = [['foo','bar','baz'],['my','your'],['holy','grail']] result = [] for d in data:

Take advantage of the fact that you can have more than one 'for' in a list comprehension:
>>> data = [['foo','bar','baz'],['my','your'],['holy','grail']] >>> [item for item_list in data for item in item_list] ['foo', 'bar', 'baz', 'my', 'your', 'holy', 'grail']
