The python operator is used to do operations on variable and their values. For example, if we want to add two numbers then we use + is called an operator. Let’s see one example to understand operators in python.
num1 = 10
num2 = 20
ans = num1 + num2
print(ans)
# output:- 30In the above program, + is an operator while num1 and num2 are operands. In this article, we will see various types of operators in python.
Types of Operators in Python:-
There are different types of operators in python listed below.
- Arithmetic Operators
- Comparision Operators
- Logical Operators
- Bitwise Operators
- Assignment Operators
- Identity Operators
- Membership Operators
Arithmetic Operators:-
Arithmetic operators are used to performing basic arithmetic operations like addition, subtraction, multiplication, division, and others. All the arithmetic python operators are given in the below table.
| Operator | Syntax | Description |
|---|---|---|
| + (Addition) | A+B | adds A and B |
| –Â (Subtraction) | A-B | subtract B from A |
| *Â (Multiplication) | A*B | multiply A and B |
| / (Division) | A/B | divide A by B (result: float) |
| // (Division) | A//B | divide A by B (result: floor (int)) |
| % (Modulus) | A%B | gives reminder of A divide B |
| ** (Power) | A**B | gives A power of B |
Precedence order of operators are Parenthese, Exponential, Multiplication, Division, Addition, and Subtraction. Let’s understand how to use all the python operators in code with an example.
A=18
B=5
add = A+B
sub = A-B
mul = A*B
div_float = A/B
div_floor = A//B
mod = A%B
power = A**B
print("A + B = "+str(add))
print("A - B = "+str(sub))
print("A * B = "+str(mul))
print("A / B = "+str(div_float))
print("A // B = "+str(div_floor))
print("A % B = "+str(mod))
print("A ** B = "+str(power))
Output:
A + B = 23
A - B = 13
A * B = 90
A / B = 3.6
A // B = 3
A % B = 3
A ** B = 1889568Comparision Operator:-
Comparison operators are used to making a comparison between values of two operands. It gives output as True or False based on the comparison. All the Comparison Python Operators are given in the below table.
| Operator | Syntax | Description |
|---|---|---|
| \== (Equal to) | A==B | return true if A and B are equal |
| > (Greater than) | A>B | return true if A is greater than B |
| < (Less than) | A<B | return true if A is less than B |
| != (Not equal to) | A!=B | return true if A is not equal to B |
| >= (Greater than or equal to) | A>=B | return true if A is greater than or equal to B |
| <= (Less than or equal to) | A<=B | return true if A is less than or equal to B |
Let’s understand above python operators using an example.
A=18
B=5
print("A == B is "+str(A==B))
print("A > B is "+str(A>B))
print("A= B is "+str(A>=B))
print("A < = B is "+str(A <= B))
Output:
A == B is False
A > B is True
A < B is False
A != B is True
A >= B is True
A <= B is FalseLogical Operator:-
Logical operators are used to performing logical operations like logical AND, logical OR. and logical NOT. All the logical python operators are given in the below table.
| Operator | Syntax | Description |
|---|---|---|
| and (Logical and) | A and B | Return true only if A and B both are true |
| or (Logical or) | A or B | Return true if either A or B is true |
| not (logical not) | not A | Return true if A is false and vice versa |
Let’s understand above python operators using an example.
A=True
B=False
_and = A and B
_or = A or B
_not = not A
print("A and B = "+str(_and))
print("A or B = "+str(_or))
print("not A = "+str(_not))
Output:
A and B = False
A or B = True
not A = FalseBitwise Operator:-
Bitwise operators are used to performing bitwise operations like bitwise and, bitwise or and many more. All the Bitwise Python Operators are given in the below table.
| Operator | Syntax | Description | |
|---|---|---|---|
| & (Bitwise and) | A & B | return A bitwise and B | |
| (Bitwise or) | A | B | return A bitwise or B |
| ~ (Bitwise not) | ~ A | return bitwise not of A | |
| ^ (Bitwise xor) | A ^ B | return A bitwise xor B | |
| >> (Bitwise right shift) | A >> B | return A right shift by B | |
| << (Bitwise left shift) | A << B | return A left shift by B |
Let’s understand bitwise python operators with help of an example.
A=8
B=3
_and = A & B
_or = A | B
_not = ~ A
_xor = A ^ B
_right_shift = A >> B
_left_shift = A << B
print("A & B = "+str(_and))
print("A | B = "+str(_or))
print("~ A = "+str(_not))
print("A ^ B = "+str(_xor))
print("A >> B = "+str(_right_shift))
print("A << B = "+str(_left_shift))
Output:
A & B = 0
A | B = 11
~ A = -9
A ^ B = 11
A >> B = 1
A << B = 64Assignment Operator:-
Assignment operators are used to assign values to python variables. All the Assignment Python Operators are given in the below table.
| Operator | Syntax | Same As | Description | |||
|---|---|---|---|---|---|---|
| \= | A=10 | A=10 | Assign value 10 to variable A | |||
| += | A+=B | A=A+B | Add value B into the value of variable A and assign it to variable A | |||
| -= | A-=B | A=A-B | Subtract the value of B from the value of A and assign it to variable A | |||
| *= | A*=B | A=A*B | Multiply the values of A and B and assign it to variable A | |||
| /= | A/=B | A=A/B | Divide value of A by B and assign it’s float value to variable A | |||
| //= | A//=B | A=A//B | Divide value of A by B and assign it’s floor value to variable A | |||
| %= | A%=B | A=A%B | Get A modulus of B and assign it to variable A | |||
| **= | A**=B | A=A**B | Get A power of B and assign it to variable A | |||
| &= | A&=B | A=A&B | Get bitwise and of A and B and assign it to variable A | |||
| = | A | =B | A=A | B | Get bitwise or of A and B and assign it to variable A | |
| ^= | A^=B | A=A^B | Get bitwise xor of A and B and assign it to variable A | |||
| >>= | A>>=B | A=A>>B | Get A left shift by B and assign it to variable A | |||

A,B=8,3
A+=B
print("'A += B' = "+str(A))
A,B=8,3
A-=B
print("'A -= B' = "+str(A))
A,B=8,3
A*=B
print("'A *= B' = "+str(A))
A,B=8,3
A/=B
print("'A /= B' = "+str(A))
A,B=8,3
A//=B
print("'A //= B' = "+str(A))
Output:-
'A += B' = 11
'A -= B' = 5
'A *= B' = 24
'A /= B' = 2.6666666666666665
'A //= B' = 2Identity Operator:-
Identity operators are used to check whether the memory locations of values of two variable are same or not. All the Identity Python Operators are given in the below table.
| Operator | Syntax | Description |
|---|---|---|
| is | A is B | Return true if memory locations of A and B are the same else return false. |
| is not | A is not B | Return true if memory locations of A and B are not the same else return false |
Let’s understand identity python operators with help of an example.
A=10
B=5
C=A
print(A is B)
print(A is not B)
print(A is C)
Output:-
False
True
TrueMembership operators:-
Membership operators are used to check whether an operand belongs to any group like list, tuple, set. All the Membership Python Operators are given in the below table.
| Operator | Syntax | Description |
|---|---|---|
| in | A in B | Return true if A belongs to B else return False |
| not in | A not in B | Return true if A does not belong to B else return False |
Let’s understand membership python operators with help of an example.
_list=["C","C++","Java","Python"]
print("Python" in _list)
print("PHP" in _list)
print("Python" not in _list)
print("PHP" not in _list)
Output:
True
False
False
True
