-- the struct module only handles sizes 2, 4 and 8. I can hack it by going via a hex representation:

but this is a pretty gross hack.
The first part also doesn't work if hex(i) has odd length. [py3k]:
bytes.fromhex(hex(10**99)[2:]) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: non-hexadecimal number found in fromhex() arg at position 82
I think the fact that it's non-trivial to get this right first time is further evidence that it would be useful to have built-in int <-> bytes conversions somewhere. Mark
