Reading 4 byte integers from binary file in Python

Question

I have a some sets of binary files (some are potentially large (100MB)) that contain 4 byte integers.

Can anyone supply a code snippet to show how to extract each 4 byte

Answer 1

Check out the NumPy fromfile function. You provide a simple type annotation about the data to be read, and the function efficiently reads it into a NumPy ndarray object.

import numpy as np
np.fromfile(file_name, dtype='

You can change dtype to reflect size and byte order as well. See here for some examples.
