Python Operators
Operators are used to perform operations on variables and values.
In the example below, we use the + operator to add together two values:
In the example below, we use the + operator to add together two values:
print(10 + 5)
Python divides the operators in the following groups:
- Arithmetic operators
- Assignment operators
- Comparison operators
- Logical operators
- Identity operators
- Membership operators
- Bitwise operators
Python Arithmetic Operators
Arithmetic operators are used with numeric values to perform common
mathematical operations:
mathematical operations:
|
Operator
+ - * / % ** // |
Name
Addition Subtraction Multiplication Division Modulus Exponentiation Floor Division |
Example
x + y x - y x * y x / y x % y x ** y x // y |
Python Assignment Operators
Assignment operators are used to assign values to variables:
|
Operator
= += -= *= /= %= **= //= &= |= ^= >>= <<= |
Example
x = 5 x += 3 x -= 3 x *= 3 x /= 3 x %= 3 x **= 3 x //= 3 x &= 3 x |= 3 x ^= 3 x >>= 3 x <<= 3 |
Same As
x = 5 x = x + 3 x = x - 3 x = x * 3 x = x / 3 x = x % 3 x = x ** 3 x = x // 3 x = x & 3 x = x | 3 x = x ^ 3 x = x >> 3 x = x << 3 |
Python Comparison Operators
Comparison operators are used to compare two values:
|
Operator
== != > < >= <= |
Name
Equal Not equal Greater than Less than Greater than or equal to Less than or equal to |
Example
x == y x != y x > y x < y x >= y x <= y |
Python Logical Operators
Logical operators are used to combine conditional statements:
|
Operator
and or not |
Description
Returns True if both statements are true Returns True if one of the statements is true Returns True if one of the statements is true |
Example
x < 5 and x < 10 x < 5 or x < 4 not(x < 5 and x < 10) |
Python Identity Operators
Identity operators are used to compare the objects, not if they are equal, but if they are actually the same object, with the same memory location:
|
Operator
& | ^ ~ << >> |
Name
AND OR XOR NOT Zero fill left shift Signed right shift |
Example
Sets each bit to 1 if both bits are 1 Sets each bit to 1 if one of two bits is 1 Sets each bit to 1 if only one of two bits is 1 Inverts all the bits Shift left by pushing zeros in from the right and let the leftmost bits fall off Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off |
