Assignment Operators in Python (original) (raw)

Last Updated : 04 Dec, 2024

The Python Operators are used to perform operations on values and variables. These are the special symbols that carry out arithmetic, logical, and bitwise computations. The value the operator operates on is known as the Operand.

Assignment Operators are used to assign values to variables. This operator is used to assign the value of the right side of the expression to the left side operand.

Python `

Assigning values using

Assignment Operator

a = 3 b = 5

c = a + b

Output

print(c)

`

**Output

8

Addition Assignment Operator

The Addition Assignment Operator is used to add the right-hand side operand with the left-hand side operand and then assigning the result to the left operand.

Python `

a = 3 b = 5

a = a + b

a += b

Output

print(a)

`

**Output:

8

**Subtraction Assignment Operator

The Subtraction Assignment Operator is used to subtract the right-hand side operand from the left-hand side operand and then assigning the result to the left-hand side operand.

Python `

a = 3 b = 5

a = a - b

a -= b

Output

print(a)

`

**Output:

-2

**Multiplication Assignment Operator

The Multiplication Assignment Operator is used to multiply the right-hand side operand with the left-hand side operand and then assigning the result to the left-hand side operand.

Python `

a = 3 b = 5

a = a * b

a *= b

Output

print(a)

`

**Output:

15

**Division Assignment Operator

The Division Assignment Operator is used to divide the left-hand side operand with the right-hand side operand and then assigning the result to the left operand.

**Syntax: a /= b

Python `

a = 3 b = 5

a = a / b

a /= b

Output

print(a)

`

**Output:

0.6

**Modulus Assignment Operator

The Modulus Assignment Operator is used to take the modulus, that is, it first divides the operands and then takes the remainder and assigns it to the left operand.

**Syntax: a %= b

Python `

a = 3 b = 5

a = a % b

a %= b

Output

print(a)

`

**Output:

3

**Floor Division Assignment Operator

The Floor Division Assignment Operator is used to divide the left operand with the right operand and then assigs the result(floor value) to the left operand.

**Syntax: a //= b

Python `

a = 3 b = 5

a = a // b

a //= b

Output

print(a)

`

**Output:

0

Exponentiation Assignment Operator

The Exponentiation Assignment Operator is used to calculate the exponent(raise power) value using operands and then assigning the result to the left operand.

**Syntax: a **= b

Python `

a = 3 b = 5

a = a ** b

a **= b

Output

print(a)

`

**Output:

243

Bitwise AND Assignment Operator

The Bitwise AND Assignment Operator is used to perform Bitwise AND operation on both operands and then assigning the result to the left operand.

**Syntax: a &= b

Python `

a = 3 b = 5

a = a & b

a &= b

Output

print(a)

`

**Output:

1

Bitwise OR Assignment Operator

The Bitwise OR Assignment Operator is used to perform Bitwise OR operation on the operands and then assigning result to the left operand.

**Syntax: a |= b

Python `

a = 3 b = 5

a = a | b

a |= b

Output

print(a)

`

**Output:

7

**Bitwise XOR Assignment Operator

The Bitwise XOR Assignment Operator is used to perform Bitwise XOR operation on the operands and then assigning result to the left operand.

**Syntax: a ^= b

Python `

a = 3 b = 5

a = a ^ b

a ^= b

Output

print(a)

`

**Output:

6

**Bitwise Right Shift Assignment Operator

The Bitwise Right Shift Assignment Operator is used to perform Bitwise Right Shift Operation on the operands and then assign result to the left operand.

**Syntax: a >>= b

Python `

a = 3 b = 5

a = a >> b

a >>= b

Output

print(a)

`

**Output:

0

**Bitwise Left Shift Assignment Operator

The Bitwise Left Shift Assignment Operator is used to perform Bitwise Left Shift Opertator on the operands and then assign result to the left operand.

**Syntax: a <<= b

Python `

a = 3 b = 5

a = a << b

a <<= b

Output

print(a)

`

**Output:

96

Walrus Operator

The Walrus Operator in Python is a new assignment operator which is introduced in Python version 3.8 and higher. This operator is used to assign a value to a variable within an expression.

**Syntax: a := expression

**Example: In this code, we have a Python list of integers. We have used Python Walrus assignment operator within the Python while loop. The operator will solve the expression on the right-hand side and assign the value to the left-hand side operand **‘x’ and then execute the remaining code.

Python `

a list

a = [1, 2, 3, 4, 5]

walrus operator

while(x := len(a)) > 2: a.pop() print(x)

`

**Output:

5 4 3
