Function show() for Canvas.text without displaying "[" and " ' "

Aurélien · January 2022

Hi,

I am designing an experiment based on the attentional-blink tutorial. The goal is to stream words.

I have a list that contains words.

I used it in a loop (here is a simpler code for illustration purposes).

In the prepare phase :

my_list_subset #a subset of the list that contains words
stimuli_canvas_list = [] #the list used in the trial 

for i, stim in enumerate(my_list_subset)
    stim_canvas = Canvas()
    stim_canvas.text(stim)
    stimuli_canvas_list.append(stim_canvas)

And in the run phase :

for words_stimuli in stimuli_canvas_list:
    words_stimuli.show()

Everything works fine except that I can't find how to use

words_stimuli.show()

to stream the words without the brackets and the quotation marks (ex : " ['word'] " , but I want "word").

I know that you can use

print(*your_list)

To print list elements without these marks but I don't know if there is something similar to use with :

my_canvas.show()

Any advice would be much appreciate !

Many thanks in advance :)

Hi @Aurélien ,

Welcome back to the forum! :)

It sounds like you defined my_list_subset as a list of lists, rather than a single list, for example like so:

my_list_subset = [["word1"], ["word2"], ["word3"]] # list of lists

instead of

my_list_subset = ["word1", "word2", "word3"] # correct  notation

Could that be the issue?

If not, could you post your actual code, rather than the simplified version?

Cheers,

Lotje

Hi @lvanderlinden ,

Thank you so much ! It solved my problem 😀.

I am not very familiar with Python objects...

In case anyone has the same kind of problem, here is a code that I found at https://stackoverflow.com/questions/952914/how-to-make-a-flat-list-out-of-a-list-of-lists

my_list_subset #list of lists 


flat_list = [] #the new list 

for sublist in my_list_subset : #a loop to make a list from the list of lists 
    for item in sublist:
        flat_list.append(item)
