I downloaded code onto our V5 brain and I keep getting the error on the brain and in our console log: File “userpy” line 27 SyntaxError: Invalid system
I’ve atached a screenshot of the code below. Any ideas? I cannot figure out how Line 27 is any different. Thank you!!!
// Beginning of Andrew's code
Python comments start with # not //
Is there a way for the line number generated by the brain at runtime for errors to be made to match the line number is user code?
Yes, we improved this for IQ 2nd Gen’s implementation for Python and in the process of rolling it across all other platforms.
The issue lies from initialization code that is tucked outside of view from the editor. We now expose this code via an expandable region to make sure the line numbers match up.
Thank you - changing from // to # for the comments worked! But now I have a Syntax Error on line 48.
I agree with what @sazrocks said…is there a way to sync up the lines of code with whatever the brain is reading? I read @trfriez’s comment, but I think that only applies to working in VEX IQ? I don’t see that handy + on VEX V5 code.
Here’s the rest of the code…anything stick out?? Thank you so much for any help!!!

Without correct formatting it’s hard to tell.
Always post code between [code] tags (or ``` tags) and keep indentation as that’s critical for Python code.
Thanks for that tip…I figured out that it was indentation, so I fixed that. Thank you SO MUCH for all of your help!!
