Python - Operators (Arithmetic, Comparison, Logical, Assignment)
Arithmetic, Comparison, Logical and Assignment Operators in Python
In Python, operators are special symbols or keywords that perform specific operations on variables and values.
The operand is the value that the operator acts on. The fundamental units of Python are operators, which let you work with variables and data values.
Operators can be categorized into different types according to their functionalities:
Arithmetic Operators:
The operator that is used to perform mathematical operations on the numerical values is known as an arithmetic operator.
| Operator | Description | Example |
| + | Addition | x+y |
| - | Subtraction | x-y |
| * | Multiplication | x*y |
| / | Division | x/y |
| % | Modulus (remainder) | x%y |
| ** | Exponential | x**y |
| // | Floor Division | x//y |
Comparison (relational) operator:
The operator that is used to return the true and false value by comparing two variables and values is known as the comparison operator.
| Operator | Description | Example |
| == | Equal to | x==y |
| != | Not Equal to | x!=y |
| > | Greater than | x>y |
| < | Less than | x<y |
| >= | Greater than Equal to | x>=y |
| <= | Less than Equal to | x<=y |
Logical Operators:
The operator that is used to combine the conditional statements is known as the logical operator.
| Operator | Description | Example |
| and | Logical AND | x>5 and y<10 |
| or | Logical OR | x>5 or y<10 |
| not | Logical NOT | not(x>5 and y<10) |
Assignment Operators:
The operator that is used to assign values to a variable is known as the assignment operator.
| Operator | Description | Example |
| = | Assignment | x=5 |
| += | Add and Assign | x+=5 (x=x+5) |
| -= | Subtract and Assign | x-=5 (x=x-5) |
| *= | Multiply and Assign | x*=5 (x=x*5) |
| /= | Divide and Assign | x/=5 (x=x/5) |
| %= | Modulus and Assign | x%=5 (x=x%5) |
| **= | Exponent and Assign | x**=5 (x=x**5) |
| //= | Floor Division and Assign | x//=5 (x=x//5) |
Bitwise Operators:
The operator that is used as a bit level is known as the bitwise operator.
| Operator | Description | Example |
| & | Bitwise AND | x&y |
| | | Bitwise OR | x|y |
| ^ | Bitwise XOR | x^y |
| ~ | Bitwise NOT | ~x |
| << | Bitwise Left Shift | x<<2 |
| >> | Bitwise Right Shift | x>>2 |
Membership Operators:
The Operator that is Tested for membership in a sequence (like lists, strings) is known as a membership operator.
| Operator | Description | Example |
| in | Returns True if a sequence contains the specified value. | a in letsupdateskills |
| not in | Returns True if a sequence does not contain the specified value | x not in letsupdateskills |
Identity Operators:
The operator that compares the memory location of the two objects is known as an identity operator.
| Operator | Description | Example |
| is | Returns True if both variable refers to the same object | a is y |
| is not | Returns True if both variables do not refer to the same object | x is not y |
Special Operators:
- Ternary Operator: This is used for the conditional expression 'a if condition else b'.
- Operator Overloading: Python lets you define how operators work with your objects. The method like '_add_', _sub_', etc.
In summary, we primarily use four main types of operators: arithmetic, comparison, logical, and assignment.
