I understand that doing the following on Windows to a binary file (a
jpeg or exe files for example) can cause file corruption, is that correct?
fp = open(file_name, 'r')
fp.close()
How can a simple open in read mode corrupt data???
You can't corrupt *that* file if you only open it. But if you *read*
it and process the input data, you'll get some garbage. And if you
write such data (to the same file or another one), it will be corrupted.
Using "rb" or "wb" for binary files won't do any harm on systems
where it doesn't matter, and it's the right way on systems where it does.
