   >>> a=54
   >>> b=41
   >>> print(bin(a),bin(b))
   0b110110 0b101001
   

2. Binary AND

   >>> print(bin(a),bin(b))
   0b110110 0b101001
   >>> c=a&b
   >>> print(c,bin(c))
   32 0b100000
   

3. Binary OR

   >>> print(bin(a),bin(b))
   0b110110 0b101001
   >>> c=a|b
   >>> print(c,bin(c))
   63 0b111111
   

4. Binary XOR

   >>> print(bin(a),bin(b))
   0b110110 0b101001
   >>> c=a^b
   >>> print(c,bin(c))
   31 0b11111
   

5. Binary Ones Complement

   >>> print(bin(a))
   0b110110
   >>> print(bin(a),bin(~a))
   0b110110 -0b110111
   

6. Binary Left Shift

   >>> print(bin(a))
   0b110110
   >>> print(bin(a),bin(a<<2))
   0b110110 0b11011000
   

7. Binary Right Shift

   >>> print(bin(a))
   0b110110
   >>> print(bin(a),bin(a>>2))
   0b110110 0b1101
   >>> quit()
