why does not else work?  
else:  
print (“not green”)  
I want to indicate when there is no green

```python
while(True):
    img = sensor.snapshot()
    for blob in img.find_blobs(thresholds, pixels_threshold=2000, area_threshold=1120, merge=True):
        if blob.code() == 2:
            img.draw_rectangle(blob.rect()) # works
        else:
            print("not green") # don't work

```

Put your code in the code tags. I can’t tell from the lack of formatting.
