How do you write a program in python to write the reverse of a number?

To write a program in Python that reverses a number, you can convert the number to a string, reverse the string, and then convert it back to an integer. Here's a simple example:

<code class="language-python">def reverse_number(num):
return int(str(num)[::-1])
number = 12345 reversed_number = reverse_number(number) print(reversed_number)  # Output: 54321
</code>

This function takes an integer input, reverses its digits, and returns the reversed number.
