[Tutor] Bounded Linear Search

[toganm at users.sourceforge.net]

Hi,
I am trying to learn programming and python and one of the books I use has 
an exercise for "Bounded Linear Search algorithm" under the heading in 
Accumulating Unique Values at
<http://homepage.mac.com/s_lott/books/nonprog/html/p08_sequence/p08_c04_list.html#list-
exercises>

I have coded the exercises as below and what I can not figure it out is the 
code works along as spin[0] and spine[-1] are not same but when it is the 
code does not work. What am I missing ?


spin=[18, 10, 2, 19, 20, 10, 2, 7, 26, 10,2,2,18]

uniq=[]

for v in spin:
    i=0
    uniq.append(v)
    while uniq[i]!=v:
        i+=1
        if uniq[i]==v:
            if i!=len(uniq)-1:
               uniq.pop(-1)

print(uniq)


Thanks
