Python Assignment Operators
Operators are used to do action or process on variables and operands. The operator usually represents as symbol for doing an action. Python has different type of operators like Arithmetic, Assignment, Relational / Comparison , Logical, Bitwise, Identity and Membership operators. Every operators are using to do different kind of operations.
In this tutorial we will learn about Python Assignment operators
Python Assignment Operators
Python Assignment Operators are used to assign the values to the variables.
| Operator | Description | Syntax | Example |
|---|---|---|---|
| = | assigns the value from one operand to another operand or mathematical operation |
result = var1 result = var1 (Arithmetic Symbol) var2 |
a = 5 c = a + b |
| += | Adds and assigns that value to the first operand | var1 += var2 | a += b is used for a = a + b |
| -= | subtracts and assigns that value to the first operand | var1 -= var2 | a -= b is used for a = a - b |
| *= | Multiplies and assigns that value to the first operand | var1 *= var2 | a *= b is used for a = a * b |
| /= | Divides and assigns that value to the first operand | var1 /= var2 | a /= b is used for a = a / b |
| %= | Modulus - Returns the remainder of first operand divided by second operand and assigns to first operand | var1 %= var2 | a %= b is used for a = a % b |
| **= | Exponentiation - Returns the first operand power of second operand and assigns to first operand | var1 **= var2 | a **= b is used for a = a ** b |
| //= | Floor Division - Divides the values of two operands and returns the integer value and assigns to first operand | var1 //= var2 | a //= b is used for a = a // b |
Code Example:
>>> var1 = 2
>>> var2 = 3
>>> var3 = var1 + var2
>>> print('Assign value => ' + str(var1) + ' + ' + str(var2) + ' = ' + str(var3))
Assign value => 2 + 3 = 5
>>> var1 = 2
>>> var2 = var3 = 3
>>> var2 += var1
>>> print('Addition and Assign => ' + str(var3) + ' += ' + str(var1) + ' = ',(var2))
Addition and Assign => 3 += 2 = 5
>>> var1 = 3
>>> var2 = var3 = 5
>>> var2 -= var1
>>> print('Subtraction and Assign => ' + str(var3) + ' -= ' + str(var1) + ' = ' + str(var2))
Subtraction and Assign => 5 -= 3 = 2
>>> var1 = 5
>>> var2 = var3 = 6
>>> var2 *= var1
>>> print('Multiplication and Assign => ' + str(var3) + ' *= ' + str(var1) + ' = ' + str(var2))
Multiplication and Assign => 6 *= 5 = 30
>>> var1 = 6
>>> var2 = var3 = 30
>>> var2 /= var1
>>> print('Division and Assign => ' + str(var3) + ' /= ' + str(var1) + ' = ' + str(var2))
Division and Assign => 30 /= 6 = 5.0
>>> var1 = 2
>>> var2 = var3 = 3
>>> var2 %= var1
>>> print('Modulus and Assign => ' + str(var3) + ' %= ' + str(var1) + ' = ' + str(var2))
Modulus and Assign => 3 %= 2 = 1
>>> var1 = 2
>>> var2 = var3 = 2
>>> var2 **= var1
>>> print('Exponentiation and Assign => ' + str(var3) + ' **= ' + str(var1) + ' = ' + str(var2))
Exponentiation and Assign => 2 **= 2 = 4
>>> var1 = 2
>>> var2 = var3 = 5
>>> var2 //= var1
>>> print('Floor Division and Assign => ' + str(var3) + ' //= ' + str(var1) + ' = ' + str(var2))
Floor Division and Assign => 5 //= 2 = 2
