Operator Functions in Python | Set 1

Python has predefined functions for many mathematical, logical, relational, bitwise etc operations under the module "operator". Some of the basic functions are covered in this article. 1. add(a, b) :- This function returns addition of 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 product of the given arguments. Operation - a * b. Output:

The addition of numbers is:7
The difference of numbers is :1
The product of numbers is:12

4. truediv(a,b) :- This function returns division of the given arguments. Operation - a / b. 5. floordiv(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. Output:

The true division of numbers is: 2.5
The floor division of numbers is: 2
The exponentiation of numbers is: 25
The modulus of numbers is: 1

8. lt(a, b) :- This function is used to check if a is less than b or not. Returns true if a is less than b, else returns false. Operation - a < b. 9. le(a, b) :- This function is used to check if a is less than or equal to b or not. Returns true if a is less than or equal to b, else returns false. Operation - a <= b. 10. eq(a, b) :- This function is used to check if a is equal to b or not. Returns true if a is equal to b, else returns false. Operation - a == b. Output:

3 is not less than 3
3 is less than or equal to 3
3 is equal to 3

11. gt(a,b) :- This function is used to check if a is greater than b or not. Returns true if a is greater than b, else returns false. Operation - a > b. 12. ge(a,b) :- This function is used to check if a is greater than or equal to b or not. Returns true if a is greater than or equal to b, else returns false. Operation - a >= b. 13. ne(a,b) :- This function is used to check if a is not equal to b or is equal. Returns true if a is not equal to b, else returns false. Operation - a != b.

Output:

4 is greater than 3
4 is greater than or equal to 3
4 is not equal to 3
