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.
import operator
a = 4
b = 3
print ( "The addition of numbers is :" ,end = "");
print (operator.add(a, b))
print ( "The difference of numbers is :" ,end = "");
print (operator.sub(a, b))
print ( "The product of numbers is :" ,end = "");
print (operator.mul(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.
import operator
a = 5
b = 2
print ( "The true division of numbers is : " ,end = "");
print (operator.truediv(a,b))
print ( "The floor division of numbers is : " ,end = "");
print (operator.floordiv(a,b))
print ( "The exponentiation of numbers is : " ,end = "");
print (operator. pow (a,b))
print ( "The modulus of numbers is : " ,end = "");
print (operator.mod(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.
import operator
a = 3
b = 3
if (operator.lt(a,b)):
print ( "3 is less than 3" )
else : print ( "3 is not less than 3" )
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" )
if (operator.eq(a,b)):
print ( "3 is equal to 3" )
else : print ( "3 is not equal to 3" )
|
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.
import operator
a = 4
b = 3
if (operator.gt(a,b)):
print ( "4 is greater than 3" )
else : print ( "4 is not greater than 3" )
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" )
if (operator.ne(a,b)):
print ( "4 is not equal to 3" )
else : print ( "4 is equal to 3" )
|
Output:
4 is greater than 3
4 is greater than or equal to 3
4 is not equal to 3
