bit operations in python

#PYTHON BITWISE OPERATORS OPERATOR DESCRIPTION SYNTAX FUNCTION IN-PLACE METHOD & Bitwise AND a & b and_(a, b) __and__(self, other) | Bitwise OR a | b or_(a, b) __or__(self, other) ^ Bitwise XOR a ^ b xor(a, b) __xor__(self, other) ~ Bitwise NOT ~ a invert(a) __invert__(self) << Bitwise L shift a << b lshift(a, b) __lshift__(self, other) >> Bitwise R shift a >> b rshift(a, b) __irshift__(self, other)

python bit

# Two's Complement binary for Positive Integers:

print(int('00100001', 2))

'''--------------------------------------------------------------------

The Operators:
x << y
Returns x with the bits shifted to the left by y places (and new bits 
on the right-hand-side are zeros). This is the same as multiplying x by 
2**y.

x >> y
Returns x with the bits shifted to the right by y places. 
This is the same as //'ing x by 2**y.

x & y
Does a "bitwise and". Each bit of the output is 1 if the corresponding 
bit of x AND of y is 1, otherwise it's 0.

x | y
Does a "bitwise or". Each bit of the output is 0 if the corresponding 
bit of x AND of y is 0, otherwise it's 1.

~ x
Returns the complement of x - the number you get by switching each 1 
for a 0 and each 0 for a 1. This is the same as -x - 1.

x ^ y
Does a "bitwise exclusive or". Each bit of the output is the same as 
the corresponding bit in x if that bit in y is 0, and it's the 
complement of the bit in x if that bit in y is 1.'''
