1. add (a, b) : — This function returns the addition of the given arguments.
Operation — a + b.

2. sub (a, b) : — This function returns the difference of the given arguments.
Operation — a — b.

3. mul (a, b) : — This function returns the product of the given arguments.
Operation — a * b.

# Python code to demonstrate how it works
# add (), sub (), mul ()

# import operator module

import operator

# Initializing variables

a = 4

b = 3

# using add () to add two numbers

print ( "The addition of numbers is:" , end = " ");

print (operator.add (a, b))

# using sub () to subtract two numbers

print ( "The difference of numbers is:" , end = " ");

print (operator.sub (a, b))

# using mul () to multiply two numbers

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 the separation of the given arguments.
Operation — a / b.

5. floordiv (a, b) : — This function also returns the division of the given arguments. But the value is an intermediate value, that is, returns the largest small integer .
Operation — a // b.

6. pow (a, b) : — This function returns raising to the power of the given arguments.
Operation — a ** b.

7. mod (a, b) : — this function returns the module of the given arguments.
Operation — % b.

# Python code to demonstrate how it works
# truediv (), floordiv (), pow (), mod ()

# import operator module

import operator

# Initializing variables

a = 5

b = 2

# using truediv () to separate two numbers

print ( " The true division of numbers is: " , end = "");

print (operator.truediv (a, b))

# using floordiv () to divide two numbers

print ( "The floor division of numbers is:" , end = " ");

print (operator.floordiv (a, b))

# using pow () to power two numbers

print ( "The exponentiation of numbers is:" , end = "");

print (operator. pow (a, b))

# using mod () to get a two-number module

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, otherwise returns false.
Operation — a & lt; b .

9. le (a, b) : — This function is used to check if ab is less than or equal to . Returns true if a is less than or equal to b, otherwise returns false.
Operation — a & lt; = b .

10. eq (a, b) : — This function is used to check if ab is equal to or not . Returns true if a is equal to b, otherwise returns false.
Operation — a == b .

# Python code to demonstrate how it works
# lt (), le () and eq ()

# import statement module

import operator

# Initializing variables

a = 3

b = 3

# using lt () to check if a is less than b

if (opera tor.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 ab is equal

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, otherwise returns false.
Operation — a & gt; b .

12. ge (a, b) : — This function is used to check whether a is greater than or equal to a or less than b . Returns true if a is greater than or equal to b, otherwise returns false.
Operation — a & gt; = b .

13. ne (a, b) : — This function is used to check if a is not equal to b or . Returns true if a is not equal to b, otherwise returns false.
Operation — huh! = B.

# Python code to demonstrate how it works
# gt (), ge () and ne ()

# import statement module

import operator

# Initializing variables

a = 4

b = 3

# using gt () to check if a is greater than b

if (operator.gt (a, b)): < / code>

    print   (  "4 is greater than 3"  ) 
   else  :   print   (  "4 is not greater than 3 " ) 
    
  # using ge () to check if ab is greater than or equal to ab  
   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 that 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"  )

Output:

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