[Python] Numeric: 'where' function conditions

Could anyone tell me the efficient way to do this? Extracting values
from an array for a single condition (say all values greater than 'x')
using 'where' and 'compress' is simple enough.
array([4, 5, 6, 7, 8, 9])

But, 'where' doesn't appear to allow for multiple conditions in one
statement. For instance, I'd like to do something like:

mask= where((3 < data <= 7),1,0)

but, this won't work.

So, the best I could come up with was this more complicated process that
requires 2 separate masks and an extra temporary array.
array([0, 0, 0, 0, 4, 5, 6, 7, 8, 9])
array([0, 0, 0, 0, 4, 5, 6, 7, 0, 0])
array([4, 5, 6, 7])

Is there a more concise way?

Thanks,

J.S.
