The equivalent expression is &= for and and |= for or.

>>> b = True >>>
   b &= False >>>
   b
False

Note bitwise AND and bitwise OR and will only work (as you expect) for bool types. bitwise AND is different than logical AND for other types, such as numeric

>>> bool(12) and bool(5) # logical AND
True

   >>>
   12 & 5 # bitwise AND

Unlike normal assignment operator, Augmented Assignment Operators are used to replace those statements where binary operator takes two operands says var1 and var2 and then assigns a final result back to one of operands i.e. var1 or var2.,For example: statement var1 = var1 + 5 is same as writing var1 += 5 in python and this is known as augmented assignment operator. Such type of operators are known as augmented because their functionality is extended or augmented to two operations at the same time i.e. we're adding as well as assigning.,Python OperatorsBitwise Operators in PythonChaining Comparison Operators in PythonTernary or Conditional Operator in PythonAugmented Assignment Operators in Python with Examples,Augmented Assignment Operators in Python with Examples

PROGRAM

# Addition
a = 23
b = 3
a += b
print('Addition = %d' % (a))

OUTPUT

Addition = 26

PROGRAM

# Subtraction
a = 23
b = 3
a -= b
print('Subtraction = %d' % (a))

OUTPUT

Subtraction = 20

PROGRAM

# Multiplication
a = 23
b = 3
a *= b
print('Multiplication = %d' % (a))

OUTPUT

Multiplication = 69

PROGRAM

# Division
a = 23
b = 3
a /= b
print('Division = %f' % (a))

OUTPUT

Division = 7.666667

PROGRAM

# Remainder or Modulo
a = 23
b = 3
a %= b
print('Remainder or Modulo = %d' % (a))

OUTPUT

Remainder or Modulo = 2

PROGRAM

# Power
a = 23
b = 3
a **= b
print('Power = %d' % (a))

OUTPUT

Power = 12167

In Python, we know how the arithmetic operators can be used to add, subtract, divide and multiply two variables.,In this article, we will learn how we can extend the functionality of an operator in a precise form at the time of evaluating an expression.,So, in this article, we learned how the augmented assignment expressions can be used in Python.,In the below program, we have evaluated the expression for the bitwise right shift between the variables x and y.

Value of z is: 25
Value of x is: 20

Value of z is: 5
Value of x is: 10

Value of z is: 150
Value of x is: 75

Value of z is: 1.5
Value of x is: 3.0

Value of z is: 5
Value of x is: 0

Value of z is: 225
Value of x is: 3375
