Assignment operators

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

a = 5
is a simple assignment operator that assigns the value5
on the right to the variablea
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
