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.
Python
Output:
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.
Python
Output:
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.
Python
Output:
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.
Python
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.

print (operator.mod(a,b))
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.
# Python code to demonstrate working of
# lt(), le() and eq()
# importing operator module
import operator
# Initializing variables
a = 3
b = 3
# using lt() to check if a is less than b
if(operator.lt(a,b)):
print ("3 is less than 3")
else : print ("3 is not less than 3")
# using le() to check if a is less than or equal to b
if(operator.le(a,b)):
print ("3 is less than or equal to 3")
else : print ("3 is not less than or equal to 3")
# using eq() to check if a is equal to b
if (operator.eq(a,b)):
print ("3 is equal to 3")
else : print ("3 is not equal to 3")
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.
# Python code to demonstrate working of
# gt(), ge() and ne()
# importing operator module
import operator
# Initializing variables
a = 4
b = 3
# using gt() to check if a is greater than b
if (operator.gt(a,b)):
print ("4 is greater than 3")
else : print ("4 is not greater than 3")
# using ge() to check if a is greater than or equal to b
if (operator.ge(a,b)):
print ("4 is greater than or equal to 3")
else : print ("4 is not greater than or equal to 3")
# using ne() to check if a is not equal to b
if (operator.ne(a,b)):
print ("4 is not equal to 3")
else : print ("4 is equal to 3")
4 is greater than 3 4 is greater than or equal to 3 4 is not equal to 3
