Python Assignment OperatorsOperator | Example | Same As | = | x = 2
| x = 2
| += | x += 2
| x = x + 2
| -= | x -= 2
| x = x - 2
| *= | x *= 2
| x = x * 2
| /= | x /= 2
| x = x / 2
| %= | x %= 2
| x = x % 2
| //= | x //= 2
| x = x // 2
| **= | x **= 2
| x = x ** 2
|
Python Comparison OperatorsEqual | x == y
| Not equal | x != y
| Greater than | x > y
| Less than | x < y
| Greater than or equal to | x >= y
| Less than or equal to | x <= y
|
| | Boolean ValuesIn programming you often need to know if an expression is True or False.
You can evaluate any expression in Python, and get the answer. | print(5 < 8)
| >>> True
| print(5 > 8)
| >>> False
|
Python Logical Operatorsand | Returns True if both statements are true | x < 5 and x < 10
| or | Returns True if one of the statements is true | x < 5 or x < 4
| not | Reverse the result, returns False if the result is true | not(x < 5 and x < 10)
|
Python Identity Operatorsis | Returns true if both variables are the same object | x is y
| is not | Returns true if both variables are not the same object | x is not y
|
| | Python Membership Operatorsin | Returns True if a sequence with the specified value is present in the object | x in y
| not in | Returns True if a sequence with the specified value is not present in the object | x not in y
|
Python Bitwise Operators&
| AND | Sets each bit to 1 if both bits are 1 | |
| OR | Sets each bit to 1 if one of two bits is 1 | ^
| XOR | Sets each bit to 1 if only one of two bits is 1 | ~
| NOT | Inverts all the bits | <<
| Zero fill left shift | Shift left by pushing zeros in from the right and let the leftmost bits fall off | >>
| Signed right shift | Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off |
