Python Operators
Python has different types of operators for different operations. They are as follows:
Arithmetic operators:
Arithmetic operators are used to perform arithmetic/mathematical operations.
| Name | Operator | Example |
|---|---|---|
| Addition | + | a+b |
| Subtraction | - | a-b |
| Multiplication | * | a*b |
| Division | / | a/b |
| Exponential | ** | a**b |
| Modulus | % | a%b |
| Floor Division | // | a//b |
Assignment operators:
These operators are used to assign values to variables.
| Name | Evaluated As |
|---|---|
| = | a=b |
| += | a+=b or a=a+b |
| -= | a-=b or a=a-b |
| *= | a*=b or a=a*b |
| **= | a**=b or a=a**b |
| /= | a/=b or a=a/b |
| //= | a//=b or a=a//b |
| %= | a%=b or a=a%b |
| &= | a&=b or a=a&b |
| ** | =** |
| ^= | a^=b or a=a^b |
| >>= | a>>=b or a=a>>b |
| <<= | a<<=b or a=a<<b |
Bitwise operators:
Bitwise operators are used to deal with binary operations.
| Name | Operator | Example |
|---|---|---|
| Bitwise AND | & | a & b |
| Bitwise OR | | | a | b |
| Bitwise NOT | ~ | ~a |
| Bitwise XOR | ^ | a ^ b |
| Bitwise right shift | >> | a>> |
| Bitwise left shift | << | b<< |
Comparison operators:
These operators are used to compare values.
| Name | Operator | Example |
|---|---|---|
| Equal | == | a==b |
| Not Equal | != | a!=b |
| Less Than | < | a<b |
| Greater Than | > | a>b |
| Less Than or Equal to | <= | a<=b |
| Greater Than or Equal to | >= | a>=b |
Identity operators:
| Name | Example | Evaluated As |
|---|---|---|
| is | a is b | Returns True if a and b are same |
| is not | a is not b | Returns True if a and b are not same |
Logical operators:
These operators are used to deal with logical operations.
| Name | Operator | Example |
|---|---|---|
| AND | and | a=2 and b=3 |
| OR | or | a=2 or b=3 |
| NOT | not | Not(a=2 or b=3) |
Membership operators:
| Name | Example | Evaluated As |
|---|---|---|
| in | a in b | Returns True if a is present in given sequence or collection |
| not in | a not in b | Returns True if a is not present in given sequence or collection |
Operator Precedence in Python:
| Name | Operator |
|---|---|
| Parenthesis | () |
| Exponential | ** |
| Complement, unary plus, unary minus | ~ , +, - |
| Multiply, divide, modulus, floor division | *, /, %, // |
| Addition, subtraction | +, - |
| Left shift and right shift operators | <<, >> |
| Bitwise and | & |
| Bitwise or and xor | ^, | |
| Comparison operators | <, >, >=, <= |
| Equality operators | ==, != |
| Assignment operators | =, %=, /=, //=, -=, +=, *= , **= |
| Identity operators | is, is not |
| Membership operators | in, not in |
| Logical operators | and, or, not |
