Removing duplicates
We want to remove duplicates from a list and keep the original order of the elements. If you convert the list to a set, then duplicates are removed, but you lose the order.
def remove_duplicates(li):
"""remove duplicates from a list by keeping the order"""
dict = {}
copy = []
for e in li:
if not dict.has_key(e):
copy.append(e)
dict[e] = 1
return copy
