A function is a named section of code in computer programming that performs a specific task. This usually entails taking some data, manipulating it, and then returning a result. Using this functions here we have executed the python program to check palindrome number using functions.

```
def isPalindrome(n):
reverse = 0
reminder = 0
while(n != 0):
remainder = n % 10
reverse = reverse * 10 + remainder
n = int(n / 10)
return reverse
num = int(input('Enter The Number'))
reverse = isPalindrome(num)
if(num == reverse):
print(num,'is a Palindrome')
else:
print(num,'is not a Palindrome')
```

Output:

Enter The Number456

456 is not a Palindrome
