This come up after installing Python Mode for Processing. in addition, programs written in python mode don't run.

for example, size(500,500) print('Hello World')

or just

print('Hello World')

has no results. Nothing happens

follow up: this comes after reading tibofordeayn's post posted on Sep 19. The Warning messages that I included above are associated with V4, which I already replaced with V3.5.4. I have no issues with V3.5.4.

Are you using Processing 3.5.4 or Processing 4? Python Mode supports Processing 3.

I was using V4. Came to the understanding that the V4 does not support Python Mode. I replaced V4 with V3.5.4

Aha - thanks @tabreturn I made the same error. Would be awesome to have a notification indicating this limitation somewhere when adding Python to Processing 4...

@surroundsound5000 -- to be fair, it is listed as Python Mode for Processing 3 in the Processing IDE's Contribution Manager window. But then again, many users make this error, and good usability design dictates one doesn't blame the user.

Maybe greying it out (in the Processing 4 IDE) like some of the other non-compatible modes (CoffeeScript, etc.) is the way to go.
