converting an int to bytes

[Skaperen]

i can convert an int to bytes by first converting to hexadecimal characters (and maybe prefixing a '0' to make an even number of digits). is there any more direct way to convert an int to the binary equivalent sequence of bytes without doing the hexadecimal conversion and/or adjusting the number of hexadecimal digits to a multiple of two.

for those of you that like to have code you can squish in your fingers...

bytes_to_int.py:

t = bytes,bytearray
def bytes_to_int(bytes=None):
    """Convert bytes or bytearray to int."""
    if bytes is None:
        return None
    if isinstance(bytes,t):
        return int.from_bytes(bytes)
    raise TypeError('arg 1 type must be bytes or bytearray')

int_to_bytes.py:

t = int
def int_to_bytes(int=None):
    """Convert int to bytes."""
    if int is None:
        return None
    if isinstance(int,t):
        h=hex(int)[2:]
        if len(h)%2:
            h='0'+h
        return bytes.fromhex(h)
    raise TypeError('arg 1 type must be int')

the above code is not tested, yet. i may test it, some day.
