Inplace operator in Python

PythonProgrammingServer Side Programming

Definition - In-place operation is an operation that changes directly the content of a given linear algebra, vector, matrices(Tensor) without making a copy. The operators which helps to do the operation is called in-place operator.

Eg: a+= b is equivalent to a= operator.iadd(a, b)

There are some operators are used for In-place operation.

iadd()

This function is used to assign the current value and add them. This operator does x+=y operation. In case of strings, numbers assigning is not performed.

Example

a =operator.iadd(1, 3);
print ("The result after adding : ", end="")
print(a)

Output

The result after adding: 5

isub()

This function is used to assign the current value and subtract them. This operator does x-=y operation. In case of strings, numbers assigning is not performed.

Example

a =operator.isub(8, 6);
print ("The result after subtracting : ", end="")
print(a)

Output

The result after subtracting: 2

imul()

This function is used to assign the current value and multiply them. This operator does x*=y operation. In case of strings, numbers assigning is not performed.

Example

a =operator.imul(8, 6);
print ("The result after multiplying : ", end="")
print(a)

Output

The result after multiplying: 48

itruediv()

This function is used to assign the current value and divide them. This operator does x/=y operation. In case of strings, numbers assigning is not performed.

Example

a =operator.itruediv(54, 6);
print ("The result after dividing : ", end="")
print(a)

Output

The result after dividing: 9

imod()

This function is used to assign the current value and divide them. This operator does x%=y operation. In case of strings, numbers assigning is not performed.

Example

a =operator.imod(10, 5);
print ("The result after modulus : ", end="")
print(a)

Output

The result after modulus: 2.0

iconcat()

This function is used to concatenate two strings.

Example

a= "jupyter”
b = "notebook"
t =operator.iconcat(a, b)
print (" After concatenation : ", end="") 
print (t) 

Output

After concatenation : jupyter notebook
