Since 7c1584aef1 MicroPython matches CPython in most cases, aside from
nested comprehensions.

description: MicroPython allows := to assign to the iteration variable in nested comprehensions, CPython does not.
|
|
cause: MicroPython is optimised for code size. Although it is a syntax error to assign to the iteration variable in a standard comprehension (same as CPython), it doesn't check if an inner nested comprehension assigns to the iteration variable of the outer comprehension.
|
|
workaround: Do not use := to assign to the iteration variable of a comprehension.
