python program for reverse of a number using type casting
In this tutorial, we are going to learn how to reverse a given number within two lines of code in Python using the type casting method.
How to reverse a number (optimum solution) in Python
Before jump into the program 1st, you have some knowledge of typecasting in Python.
following are the way of typecasting in python:
let’s consider two variable
x=’123′ (string variable)
y=123 (integer variable)
1)integer to string:
—-> o/p= ‘123’
2)string to an integer:
3)integer to float:
In similar way in this program we are going to use type casting .
Now move on the program.
first, take a value from the user:
#take integer as a string input from users. x=input("Please enter a integer ")
Now use type cast concept to convert a string because the reverse of number is easier than the reverse of the string so we directly taking a number as a string then reverse them.
the reverse of given number which is taken by the user in a string format.
#reverse of string instead of integer. y=x[::-1]
Now again typecast the string into integer and print it as an output.
#type cast from string to integer. y=int(y) print("Reverse of given number = ",y)
let’s combine the whole code together :
# Reverse of a number in python within very less line of code. #take integer as a string input from users. x=input("Please enter a integer ") #reverse of string instead of integer. y=x[::-1] #type cast from string to integer. y=int(y) print("Reverse of given number = ",y)
Please enter a integer 156 Reverse of given number = 651
