The following line should do what you are looking for: We convert the int to string ,then reverse it and again convert in int and store reversed number in b, This code will not work if the number ends with zeros, example 100 and 1000 return 1, #// division that results into whole number adjusted to the left in the number line. The range () function in Python 3 is a renamed version of the xrange (). If you are having n as integer then you need to specify it as str here as shown. Take the number num as input from the user. There are numerous ways to reverse a number in python, which are discussed below. In each case we will check whether the number is in range of 32-bit integers. Example Code: Inside the loop, store the remainder of the orignal_number divided by 10 in a remainder variable. To solve this, we will use the Python Code.
