python - Converting a numpy string array to integers in base-16 -

i looking way convert array of strings in numpy integers represent in hexadecimal. in other words, array version of:

int("f040", 16) 

i can convert string array integers base-10 calling arr.astype(numpy.int32), can't see obvious way convert them base-16. know of way this?

ar = ['f040', 'deadbeaf']  int_array = [int(a, 16) in ar] print int_array 

output:

[61504, 3735928495l]
