  • I've just sent it!

  • Line 171 misses a closing parenthesis.

  • Global name 'expyriment' is not defined

  • You will need to import the expyriment package, in order to use it in Python.

    I think at this point this forum thread might not be the best way for you to proceed. I get the impression that you might benefit more from first strengthening your general knowledge of Python (there are good free books available) and then have a look at the official Expyriment documentation. Especially the Getting Started Tutorial and the Example Experiments should be helpful to understand the general way Expyriment works.


  • I thank you for your precious suggestion and material.

    Yours faithfully,
