Has Python 3 to_bytes been back-ported to python 2.7?

Question

This is the function I'm after: -

http://docs.python.org/3/library/stdtypes.html#int.to_bytes

I need big endianness support.

Answer 1

Based on the answer from @nneonneo, here is a function that emulates the to_bytes API:

def to_bytes(n, length, endianess='big'):
    h = '%x' % n
    s = ('0'*(len(h) % 2) + h).zfill(length*2).decode('hex')
    return s if endianess == 'big' else s[::-1]
