Research direction
Reproduce the linked example in the editor and inspect the generated Python for the import and change-variable expression. Trace the block's code-generation path; the issue is done when the example imports successfully on the device and the generated code no longer produces the reported confusing expression.
Written by the indexing model from the issue text.
Description
The 'change variable by' block causes the following import statement to be emitted:
from numbers import Number
Which in turn causes an ImportError on the device.
It also generates rather confusing code:
count = (count if isinstance(count, Number) else 0) + -1
