Hi, Basically I want to put my responses for each of the outputs of my loop (answers yes or no to different contrast numbers) into an empty list ... so I would have a list for each contrast corresponding to how many yes or no's there were?

```
from observerClass import observer
import numpy
obs1 = observer(0.2, 0.05)
obs2 = observer(0.1,0.05)
for cont in numpy.linspace(0.0,1.0,10):
print 'cont is', cont
for repN in range(10):
print cont, obs1.getResponse(cont) <--- this generates a yes or no to the cont
```

Any help would be much appreciated!
