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.'''
