[solved] set a global loop_variable

berlin · February 2014

Hello,

i would like to use an inline_script in a loop_sequence and set variables in the inline_script to be written into the log_file, i.e.

exp.set("stimuli",stimuli[number])

The variable [number] is set in the loop and can`t be used in the inline_script because it is Opensesame_Code and not global (am i right?).

Is there any way to use [number] in an inline_script?

Thanks a lot,

Ben

Hi Ben,

You cannot use the square-bracket syntax when using Python code. Instead, you should use self.get() to retrieve an in-the-GUI defined variable in an inline_script. So:

# Retrieve the variable 'number', which is set in a loop item:
# Thus: FROM GUI/OpenSesame code TO Python code:
number = self.get("number")

# Set the variable 'stimuli'.
# Thus: FROM Python code TO GUI/OpenSesame code:
exp.set("stimuli", number) # or whatever value you want to give to the variable.

thank you so much! now everthing works fine!

in combination with self.log i was able to write all variables in into the log:

self.log('%s;%s;%s' % (self.get('var1'),self.get('var2'),self.get('var3')))

thanks a lot again!
