# Python - cmp() Method

PythonServer Side ProgrammingProgramming

The cmp() is part of the python standard library which compares two integers. The result of comparison is -1 if the first integer is smaller than second and 1 if the first integer is greater than the second. If both are equal the result of cmp() is zero.

Below example illustrates different scenario showing the use of cmp() method.

## Example

Live Demo

def cmp(x, y):
return (x > y) - (x < y)
#x>y
x = 5
y = 3
print("The cmp value for x>y is : ",cmp(x, y),"\n")
#x<y
x = 7
y = 9
print("The cmp value for x<y is : ",cmp(x, y),"\n")
#x=y
x = 13
y = 13
print("The cmp value for x=y is : ",cmp(x, y))
#odd and even
k = 16
if cmp(0, k % 2):
print("\n","The given number",k,"is odd number ")
else:
print("\n","The given number",k,"is even number")
k= 31
if cmp(0, k % 2):
print("\n","The given number",k,"is odd number")
else:
print("\n","The given number",k,"is even number")

## Output

Running the above code gives us the following result −

The cmp value for x>y is : 1

The cmp value for x<y is : -1

The cmp value for x=y is : 0

The given number 16 is even number

The given number 31 is odd number
