Python provides methods in its definition to perform operations in place, i.e. perform assignment and evaluation in one expression using the operator module. For example,
x + = y is equivalent to x = operator.iadd (x, y)
Some important inplace operations :
1. iadd () : — this function is used to assign and add the current value . This operation performs the operation " a + = b ". The not assignment is true for immutable containers such as strings, numbers, and tuples.
2. iconcat () : — This function is used to concatenate one line at the end of a second.

Output:
The value after adding and assigning: 5 The string after concatenation is: pythonengineering
3. isub () : — This function is used to assign and subtract the current value . This operation performs the " a = b " operation. The not assignment is true for immutable containers such as strings, numbers, and tuples.
4. imul () : — This function is used to assign and multiply the current value . This operation performs the operation " a * = b ". The not assignment is true for immutable containers such as strings, numbers, and tuples.

Output:
The value after subtracting and assigning: 1 The value after multiplying and assigning: 6
5. itruediv () : — This function is used to assign and divide the current value . This operation performs the " a / = b " operation. The not assignment is true for immutable containers such as strings, numbers, and tuples.
6. imod () : — This function is used to assign and return the remainder . This operation performs the operation " a% = b ". The not assignment is true for immutable containers such as strings, numbers, and tuples.

Output:
The value after dividing and assigning: 2.0 The value after modulus and assigning: 4
