Python expects a whitespace before and after an arithmetic operator but complains about whitespace around = Is this a general python rule or something which has been decided by Rhino developers? [image] [image]

The yellow triangle things are linting warnings, not errors. You can ignore them, the code will run just fine. As pointed out by @AndersDeleuran , line 8 is invalid syntax. Don’t mix the two issues (linting warnings vs code errors), don’t get confused by them. I would turn off the linter (diagnost…

[image] Martin Siegrist: but complains about whitespace around = Hmm, I’m not seeing that, no line too long or whitespace messages here. Is this ScriptEditor in Rhino or the Python script component in GH?

It’s in the Python script editor in Grasshopper.

(Just saying … I’m no more a Rhino user, I’m retired :blush: ) pycodestyle should be about style conventions only. It shouldn’t prevent the code from running.

Here’s a script in a Grasshopper file: python_whitespace.gh (4.6 KB) [image] That’s what I see. Line 8 raises no problem when changed to a = 1 + 1 Line 10 font_style = 0 however is fixed by removing the whitespaces. I’ve been looking at the reference here: 2. Lexical analysis — Python 3.12.0…

I only see this: [image] For me all of these work without a problem message a=1 + 1 a=1+1 a = 1+1 a = 1 + 1 Is there some sort of ‘grammar’ checker that you turned on? The rs.AddText() throws an error, but I don’t think that is the complaint here. RhinoCodePluginGH.Legacy.NotSupportedInGH…

Hi, you are doing two different things and its a flaw that Python devs decided to use the equals operator for argument assignment. See: font = “Arial” initializes a variable. some_func(some_number=42) specifies an argument now consider: font = “Arial” write_text(font=“Bahnschrift”) print(fon…

FWIW those warnings are generated by a linter. I believe you can turn them off.

This might help: [image] Rhino 8 Feature: ScriptEditor (CPython, CSharp) Serengeti (Rhino 8 BETA) Indeed, so does mine. You can right-click the editor window and select Language Options and then disable Diagnostics (Linting). I assume this works in the non-Grasshopper edi…

Static Analysing/Linting is something good. A restrictive linter like you see in Pycharm is really good. Because if you work within a team, then there is no endless talk about code styling and metrics. Just take it, no discussion anymore about personal preferences. I had endless talks about it in th…

This might help:

Edit: On a side note, the error messages might be improved. In this case, by raising a syntax error exception and providing more useful information ala the current GHPython component and IDLE (paging doctor @eirannejad):
