Python 3: Operators
Arithmetic Operators
| purpose | syntax |
|---|---|
| addition | a + b |
| Subtraction | a - b |
| Negation | - a |
| Multiplication | a * b |
| Division | a / b |
| Division | a // b |
| Modulo | a % b |
| Exponentiation | a ** b |
Assignment Operators
| purpose | syntax |
|---|---|
| add and assign | c += 2 |
| substract and assign | c -= 2 |
| multiply and assign | c *= 3 |
| exponent and assign | c **= 2 |
| divide and assign | c /= 2 |
| modulus (remainder) and assign | c %= 5 |
| quotient and assign | c //= 5 |
Note: Python doesn't support ++ or --.
Warning: ++i may not generate any error, but it doesn't do anything.
Bit Operators
| purpose | syntax |
|---|---|
| and | a & b |
| or | a | b |
| xor | a ^ b |
| invert | ~ a |
| Right Shift | a >> b |
| Left Shift | a << b |
# Python 3 # 0b101 would mean binary 101 # the "{:2b}" means print in binary, and use 2 slots. # bitwise And print( "{:2b}".format(0b11 & 0b10) ) # binary 10 # bitwise Or print( "{:2b}".format(0b11 | 0b10) ) # binary 11 # xor. true if both sides differ print( "{:2b}".format(0b00 ^ 0b10) ) # binary 10 # binary invert print( "{:2b}".format(~ 0b1) ) # binary -10 (odd result!)
Sequence (list etc) Operators
Boolean Operators
