Dear all,

if I have a ndarray like array([1,2,3,2,3,1,1,1,2,2,....,2,2,3]) containing some values that are flag for data quality. how can list all the values in this array, like doing a descriptive statistics. I guess I should use Scipy statistics ? Thanks for any ideas.

Not sure what you are asking for np.unique to get unique values selecting by mask: mask = (myarr == 3), arr[mask] or statistics of another variable by groups/flags: np.bincount(arr, weights=myvar) Josef
