  Hello,

  I do not know it is answer your question but why not doing the inverse?

  x = 'NAME'
  var.Stim = x
  exec("%s = canvas()" % x)
  path = ...
  NAME.image(path)
  t = NAME.show()
  

  Best,

  Hi Sylvain,

  thanks for your answer but that does not help.
  My stimuli are first created and put into a list. The list is shuffled. Then i present them in a sequence. I want to log the presented stimulus before each response.

  Usually i made a workaround by this:

  if NAME[i] == 'NAME1':
      var.Stim='NAME1'
  elif NAME[i] == 'NAME2':
      var.Stim='NAME2'
  

  This works nicely to log the Stim as a string.
  However, this gets very long if the list includes many canvas.
  I thought is would be much nicer, if there would be a function that draws on the name of the canvas.
  Something like:

  var.Stim=canvas_name(NAME[i])

  @sebastiaan & @eduard: Is there something like that?

  Hi,

  In your first example, you're hardcoding the name of Canvas, which is NAME. Hence, you can simply do the following:

  NAME = canvas()
  path = ...
  NAME.image(path)
  t = NAME.show()
  var.Stim = 'NAME'
  

  But I don't think that this is what you have in mind. What do you want to do? Perhaps you can store the Canvas objects in a dict, where the name serves as the key?

  Cheers!

  Hey,

  Or why not just having two lists, the first one with the name of the canvas, and the second with the canvas() themselves? Like:

  from random import shuffle
  
  name_canvas = list()
  shape_canvas = list()
  index_canvas = range(10)
  
  for i in range(10):
      c = canvas()
      c.text('blabla' + str(i))
      shape_canvas.append(c)
      name_canvas.append('name' + str(i))
  
  shuffle(index_canvas)
  
  for i in index_canvas:
      var.Stim = name_canvas[i]
      shape_canvas[i].show()

  I also thought about the two lists, but there was the problem with the shuffling.
  Great idea to shuffle i and not the list!

  Nice! Thanks!
  OS Team you are the BEST!
