Assigning SOA randomly without repetition with Inline Script

  Hi S_H,

  Using print in inline script might give you some insight in a situation like this.

  print self.experiment.get("ChooseSOA")
  

  will print '0'

  print ChooseSOA
  

  will print your list [100, 100, 100, 200, etc. ]

  Basically you use both a local and a global variable ChooseSOA. You could make this work by filling the global variable ChooseSOA with you local list instead of '0' like this:

  import random
  ChooseSOA=[100 for i in range(50)]+[200 for i in range(55)]
  random.shuffle(ChooseSOA)
  self.experiment.set("ChooseSOA",ChooseSOA)
  

  Another thing; instead of

  self.experiment.set("SOA", self.experiment.get(ChooseSOA.pop()))
  

  you want to use

  self.experiment.set("SOA", self.experiment.get('ChooseSOA').pop())
  

  because you are trying to pop a value from list self.experiment.get('ChooseSOA')

  And last but not least if you are using OpenSesame 3 you want to be using the var object

  Hope this helps and please correct me if I'm wrong,
  Jarik

  Dear Jarik!
  Thank you very much for your kind answer!

  I rewrote my code according to your detailed suggestions and now I'm having: "'unicode' object has no attribute 'pop'".

  I used print in order to spot the problem. at the end of the first script I wrote print(len(ChooseSOA)) and the length was 105, as it should be. at the beginning of the second script(before setting "SOA") I wrote print(len(self.experiment.get("ChooseSOA"))) and it oddly printed 616.

  Do you have any idea what am I doing wrong now?
  (btw, I am using version 2.8.7 and I'm not able to update it at the moment...)

  Thanks!

  Couldn't find 2.8.7 so I used 2.9.7 to test:

  I think you will be OK using the local variable ChooseSOA because all inline_script items share the same workspace:

  self.experiment.set("SOA", ChooseSOA.pop())
  print self.experiment.get("SOA") #to check
  

  Note you will have to do

  self.experiment.set("ChooseSOA",ChooseSOA)
  

  after the shuffle if you want to be able to log the complete ChooseSOA list with the logger item!
