numpy slicing - TypeError: only integer scalar arrays can be converted to a scalar index

Question

import numpy as np

data = np.fromfile('pattern1.ktx', dtype=np.byte)

print ('endianness:', hex(data[12:13]))

Result: TypeError: only integer scalar arrays can be converted to a scalar index

Looks simple enough? I'm not getting it though. How to fix this? Thank You.

How about this one?

    b = np.frombuffer(np.array(data[12:12+4], dtype=np.byte), dtype=np.uint32)
    print ('endianess:', hex(b))

Same error. How to fix?

ya, that's it, brainfreeze. Reaching for the coffee just now. Thank You. — Stan S.

OK, it returns a list for some reason, so have to index it.

b = np.frombuffer(np.array(data[12:12+4], dtype=np.byte), dtype=np.uint32)
print ('endianess:', hex(b[0]))

Error fixed.
