One liner in python to get a uniquified list
In almost every list processing from various sources, we need to unique elements in the list. Here is an easy method to do so.
orig_list = [1,2,"a",3,3,2,"tux"]
unique_list = list(set(orig_list))
print unique_list
>>> ['a', 1, 2, 3, 'tux']
This doesn’t preserve the order of the list. If you want to preserve the order you may want to do something like this
unique_list = list(set(orig_list))
unique_list.sort(cmp = lambda x,y: cmp(orig_list.index(x), orig_list.index(y)))
