Reading binary file and looping over each byte

Question

In Python, how do I read in a binary file and loop over each byte of that file?

Answer 1

Python 3, read all of the file at once:

with open("filename", "rb") as binary_file:
    # Read the whole file at once
    data = binary_file.read()
    print(data)

You can iterate whatever you want using data variable.
