Please explain me in simple language what are in place operator with example?

Answer 1

Unlike the inbuilt Python operators & operator functions, the Inplace operator functions perform computation & assignment in a single statement. For example, the standard operator functions like add (), mul () etc take twoparameters, perform the operation of them & return the resultant.

The operators which helps to do the operation is called in-place operator. ... Eg: a+= b is equivalent to a= operator.iadd(a, b)
