Reading a Binary file Binary files are basically the ones with data in the Byte format (0’s and 1’s). This generally doesn’t contain the EOL(End of Line) so it is important to check that condition before reading the contents of the file. We can open and read the contents of the...

In this example, we open a file namedexample.binin binary mode ("rb") and read the first 10 bytes from the file. The bytes are then stored in thebytes_datavariable, which we print to the console. Flowchart The following flowchart illustrates the process of reading bytes from a file in...
