Bug in remove command in Web VPython 3.2?

[Jethomas5]

bb=[1, 2, 3]

bb.remove(1)

aa=[vec( -1.5, -1.5, 1.5 ), vec( -1.5, 1.5, -1.5 ), vec( 1.5, -1.5, -1.5 ), vec( 1.5, 1.5, 1.5)]

aa.remove(vec( -1.5, -1.5, 1.5 ))

ValueError: < -1.5, -1.5, 1.5 > not in list

[Harlan Gilbert]

It works if you assign 

x=vec…

aa=[x, …

aa.remove(x)

That's very odd. It looks like it's a bug in the RapydScript-NG Python-to-JavaScript transpiler, and I've asked its developer about this. Thanks for the report.

Probably the __hash__ method of vpython.vector class does not return same value for 2 objects constructed with vector() constructor with same numeric input values. Maybe due to vector() implementation or, if not the case and like Bruce suggests, due to transpiler. 

If at transpiling level, can result from different origins though.

It's tricky indeed

It's not just vectors. Here is the report I made to the RapydScript-NG developer REPL is a place where you can try out the transpiler: )https://sw.kovidgoyal.net/rapydscript/repl/

The following program throws an error in the REPL: ValueError: [1, 2, 3] not in list

a = [[1,2,3], 5, 10]
a.remove([1,2,3])
print(a)

Does this make any sense to you? In contrast, print([1,2,3] in a) yields True.

[Bruce Sherwood]

Web VPython now correctly handles the "index", "remove", and "in" methods for lists that contain vectors and/or lists.

Thanks for the report!
