SyntaxError: unexpected EOF while parsing

mhilliard2

Hello,

I am attempting to create a Digit Symbol Substitution Task on OS. When I run this task I am receiving the error:

Inline script, line 0

  ^

SyntaxError: unexpected EOF while parsing

I would appreciate some feedback in regard to what is causing this error? Currently not all of the trials are running fully & I am confused because I have not incorporated the in-line script function into this test yet.

Thank you!

Hi,

The = is a special character in the loop table. If you put it in there Opensesame tries to interpret what follows as Python code. As there is nothing following, you'll get the Syntaxerror. A workaround is to save the equal as a variable and load the variable into the loop table. See attachment

Thank you for your help with this. I will keep that in mind moving forward.

Now that the error is resolved, I am attempting to assign the number table of my sketchpad as designated mouse response buttons (1-9). I have been searching for tutorials on how to implement button's into the sketchpad, however I am still having difficulties. Ultimately I want to be able to call on the button name to give feedback. Do you have any suggestions on how to go about this process?

Thanks again!

You can either use forms with the button widgets, or potentially also the cursor_roi functionality.

Give it a try and let us know whether it works.

The cursor_roi functionality seems to be performing well, thank you for the suggestion!

I seem to have run into a similar error as last time, it states:

DSST.osexp

item-stack: ExpSeq[run].PracticeLoop[run].PracticeSeq[run].ClickLoop[run].ClickSeq[run].PracticeResp[run]

time: Fri Nov 11 16:13:25 2022

exception type: TypeError

exception message: sequence item 0: expected str instance, int found

Could you provide some insight as to what this means? I am not having much luck finding answers as to what causes this error.

Thank you!

Hi @mhilliard2

Is this question still bug you, or has it been resolved by now, perhaps in this discussion?

Thank you for following up on this! This specific problem has been resolved. I have another issue with my task in the process of being resolved in the forum you have linked.

Unexpected EOF( End Of File ) while parsing is a syntax error which means the end of source code is reached even before all the blocks of code are completed. This happens in a number of situations in Python, such as:

• Missing or unmatched parentheses.
• Forget to enclose code inside a special statement.
• Unfinished try statement.

To solve this error, first check to make sure that every if statement, for loop, while loop, try statement and function contains code. Second, check to make sure you close all the parenthesis in your code. Moreover, you can avoid this problem by keeping code neat and readable, making it easier to find and fix the problem whenever the error does occur.
