In this program, You will learn how to check a number is a palindrome or not using a function in Python.

`Some list are: 11 22 121 12321`

## Example: How to check a number is palindrome or not using a function in Python.

```
def reverse(n):
rev = 0
while n > 0:
r = n % 10
rev = rev * 10 + r
n = int(n / 10)
return rev
x = int(input("Enter a number:"))
result = reverse(x)
if result == x:
print("Number is palindrome:", x)
else:
print("Number is not palindrome:", x)
```

#### Output:

```
Enter a number:121
Number is palindrome: 121
```
