Python Bitwise Invert Oddity

# binary invert
print( "{:b}".format(~ 0b1) )   # prints -10 WTF?

here, we have a binary number 1. Its bitwise inversion should be 0. But python gives “-10”, wtf? (same in python 2.7.3 and 3.2.3)

it seems, python now represent numbers by certain infinite sequence of bits, and negative numbers starts with 1. But i don't quite get it.

i haven't worked with bitwise operations before. Is this the behavior in other langs?

If you have a question, put $5 at patreon and message me.
