I'm trying to work through the Narnia challenges on Overthewire server. I've been having trouble with some of the challenges and looked at some tutorials, which are all pretty old and use python 2.
I've been noticing that, when using python3, nothing seems to work as it should. Overflow padding doesn't seem to work right and the numbers don't seem to line up correctly.
I've been using byte-strings with little-endian hex format '\xff\xff\xff\xff', and sys.stdout.buffer.write().
Any one have any ideas why python3 in this context is functioning so strangely ?
