Trouble to create a list without duplicates

Joan_Belo

Hey guys,

Maybe I made a very naive mistake but when I try to create a list without duplicates It doesn't work and I can't figure it out why... While the same piece of code works perfectly in a Python interpretor.

There is my code :

import random

for item in range (1,(var.Level +1)):

var.r = random.randint(1,9)

if var.r not in var.x: "<-- Here is my problem. It seams that the test is not done"

var.x.append(str(var.r))

When I print var.x sometimes I have duplicates.

Does someone has an idea about this problem ?

Thanks in advance,

Joan

Hi Joan,

I can't tell you what is wrong, because you haven't added the part of the code in which you define var.x. The code itself looks alright, I think. An easier way to create a list without duplicates is using `sets`

For example:

var.x = set()
for item in range (1,(var.Level +1)):
    var.x.update(random.randint(1,9))
var.x_list = list(var.x)

Hope this helps,

Eduard

Hi eduard,

Thanks for the quick response.

Well, this is because I defined the variable x at the beggining of the experiment. I have an inline script where I define all the variables.

But thanks for the trick, I'll test that and let you know if it is good :)
