Operator Functions in Python

Python has predefined functions for several mathematical, logical, relational, bit wise etc operations under the module “operator”. a number of the essential functions are covered during this article.

1. add (a, b) : This function returns additionof the given arguments.
   Operation – a + b.
2. sub (a, b):This function returns difference of the given arguments.
   Operation – a – b.
3. mul (a, b): This function returns productof the given arguments.
   Operation – a * b

    4. true div(a,b) :- This function returns division of the given arguments.
Operation – a / b.

     5. floor div(a,b) :- This function also returns division of the given arguments. But the value is floored value i.e. returns greatest small integer.
Operation – a // b.

     6. pow(a,b) :- This function returns exponentiation of the given arguments.
Operation – a ** b.

      7. mod(a,b) :- This function returns modulus of the given arguments.
Operation – a % b.
