Look at the code below
def unique(s):
return list(set(s))
def unique2(keys):
unique = []
for i in keys:
if i not in unique:unique.append(i)
return unique
tmp = [0,1,2,4,2,2,3,4,1,3,2]
print tmp
print unique(tmp)
print unique2(tmp)
--------------------------
[0, 1, 2, 4, 2, 2, 3, 4, 1, 3, 2]
[0, 1, 2, 3, 4]
[0, 1, 2, 4, 3]
As you can see the end result is not the same.
I must get the end result [0, 1, 2, 4, 3] and not [0, 1, 2, 3, 4].
Thats why I use unique2()
