Python LED sample does not work due to mixup between module alias name and an object name #614
Traceback (most recent call last):
File "led.py", line 46, in
main()
File "led.py", line 29, in main
led = led.Led(2)
UnboundLocalError: local variable 'led' referenced before assignment
Note that "led" is used both as a module alias in the import command and as an object name in the assignment command. Consider renaming one of these "led"s with a distinct name
