## Assignment operators

• Assignment operators are used in Python to assign values to variables.

• a = 5 is a simple assignment operator that assigns the value 5 on the right to the variable a on the left.

## python +=

A little bit subtle or confusing in python is the plus equals += operator

	x = 1
x += 2 # add 2 to x
print("x is",x)
x <<= 3 # left shift by 2
print('x is',x)
x **= 4 # x := x^2
print('x is',x)



The Above Code Outputs

	x is 3
x is 24
x is 331776



Here’s the table for Reference

Symbol Example Equivalent to
= x = 5 x = 5
+= x += 5 x = x + 5
-= x -= 5 x = x – 5
*= x *= 5 x = x * 5
/= x /= 5 x = x / 5
%= x %= 5 x = x % 5
//= x //= 5 x = x // 5
**= x **= 5 x = x ** 5
&= x &= 5 x = x & 5
|= x |= 5 x = x | 5
^= x ^= 5 x = x ^ 5
>>= x >>= 5 x = x >> 5
<<= x <<= 5 x = x << 5
