You can iterate a string in python, and you'll be iterating by each character
There you go:
a = input("Enter : ")
x = [num for num in a] # Getting the individual digits
b = reversed(x) # reversed() is a built in function
print("".join(b))

Python Program to Reverse a Number - GeeksforGeeks
November 18, 2025 - This method reverses the number by converting it to a string, slicing it in reverse order and converting it back to an integer. ... This method extracts digits from the end of the number using % 10 and builds the reversed number digit-by-digit. ... This method converts the number to a string and reverses it by iterating through its characters. ... Explanation: The loop adds each character at the beginning of rev, forming the reversed order. Recursion works by repeatedly removing the last digit from the number and building the reversed number during the returning phase.
Can anyone explain how to reverse a integer number?
That's hardly cheating, and is now I'd do it unless that method was explicitly forbidden (I had that once). Your div/mod way is more complicated, and in my experience, likely doesn't have much in the way of noticeable performance advantages anyway. Abusing strings is often a good solution surprisingly (but consider each case individually). More on reddit.com

Python Program to Reverse a Number
Now supply the input say 236 as number, press ENTER key to find and print its reverse like shown in the snapshot given below: The dry run of above program with 236 as user input, goes like: When user enters the number say 236, it gets stored in num. So num=236 · The condition (of while loop) num!=0 or 236!=0 evaluates to be true, therefore program flow goes inside the loop and executes all the three statements present inside the block of this loop

February 1, 2022 -
Sorry if that sound like stupid, I'm just a newbie to programming
At first I thought it was easy and started writing code and I find myself with bunch of errors.
Then I came up with this:
number = 12345 reverse = str(number)[::-1] print(reverse)
It's just cheating you can say, I converted integer into string and made that string reverse.
After a while I thought, I'm just stupid to code like this but then later I googled and I found this solution which is more complicated to understand:
number = 12345 reverse = 0 while number > 0: last_digit = number % 10 reverse = reverse * 10 + last_digit number = number // 10 print(reverse)
Can anyone please explain what's going on here?

It's also worth noting they are not the same. Because your method not only returns a string, it also evaluates the reverse as a string. e.g. number = 12340 #Notice the number ends in 0 string result is: '04321' integer result is: 4321
