Turning off odd LEDs

[thescloon]

I'm working on a project where the LED strips are underneath the keys. Because of this. the odd numbered LEDs are visible between the gaps. I've tried adding to visualizer.py the following code:

for x in range(1, 121, 2):
ledstrip.strip.setPixelColor(x, Color(0, 0, 0))

I inserted it just before the ledstrip.strip.show() command:

for x in range(1, 121, 2):
    ledstrip.strip.setPixelColor(x, Color(0, 0, 0))
ledstrip.strip.show()

I've very familiar with the Arduino neopixel library but am a complete noob when it comes to python on raspi. I made the change via nano and SSH. Upon reboot there is no output to the strip.

Not sure why. but the third attempt seemed to work!
