How can I find the indices of an array with float values in python?

[David Raymond]

Maybe something along the lines of...

indices = [i for i, val in enumerate(x) where 0 <= val <= 15000]

Sorry for re-posting with a correction.

I have an array (numpy.ndarray) with shape (1500L,) as below:
 
 x = array([  3.00000000e+01,   6.00000000e+01,   9.00000000e+01, ...,
          4.49400000e+04,   4.49700000e+04,   4.50000000e+04])
 
Now, I wanted to determine the indices of the x values between 0.0 and 15000.0. While this is simple in MATLAB or IDL by using find or where functions, I was unable to find a best way to find the indices of all elements between 0.0 and 15000.0 in the x array. Can you please suggest me a solution for the same?
