[issue27637] int.to_bytes(-1, ...) should automatically choose required count of bytes

[Марк Коренберг]

Марк Коренберг added the comment:

Oops.

def serialize(value: int, signed=True) -> bytes:
    x = value.to_bytes(-1, 'big', signed=signed)
    l = len(x).to_bytes(4, 'big', signed=False)
    return l + x

assert len(serialize(0)) == 4 + 0 # see Issue27623
assert len(serialize(120)) == 4 + 1
assert len(serialize(130)) == 4 + 2
assert len(serialize(130), False) == 4 + 1
