Python: Bitwise Operators

Literal expression for number in binary form

0b101 mean binary number 101

print(0 == 0b0)
print(1 == 0b1)
print(2 == 0b10)
print(3 == 0b11)

Print number in binary form

print("{:b}".format(0) == "0")
print("{:b}".format(1) == "1")
print("{:b}".format(2) == "10")
print("{:b}".format(3) == "11")

• "{:b}" means print in binary.
• "{:2b}" means print in binary, and use 2 slots.

Bitwise Operators

Bitwise And &

print(0b11 & 0b10 == 0b10)

Bitwise Or |

print(0b11 | 0b10 == 0b11)

Xor ^. return 1 if digits differ.

print(0b00 ^ 0b10 == 0b10)

Binary invert ~

print(~0b1 == -0b10)

• binary right shift >>
• binary left shift <<
