NettetLeft shift (<<) Integers are stored, in memory, as a series of bits. For example, the number 6 stored as a 32-bit int would be: 00000000 00000000 00000000 00000110. … NettetYou can do a bitwise shift padding with zeros with the bitstring module using the >>= operator: >>> a = BitArray (int=-1000, length=32) >>> a.int -1000 >>> a >>= 3 >>> a.int …
