In this python function program, we will reverse an integer using a function.
What is Function?
It is a block of code that executes when it is called.
To create a function use def keyword.
Steps to solve the program
- Create a function reverse.
- Use the def keyword to define the function.
- Take a number as input through the user and create a variable rev and assign its value equal to 0.
- Use a while loop to find the reverse of a number.
- While num is greater than 0 divide the number by 10 using % to find the remainder.
- Multiply the rev by 10 and add the remainder to it.
- Now divide number by 10 using //.
- Print the final output.
- Call the function to see the output.
def reverse():
num=n=int(input("Enter a number: "))
rev=0
while n>0:
r=n%10
rev=(rev*10)+r
n=n//10
print("Reverse number: ",rev)
reverse()
Output :
Enter a number: 225
Reverse number: 522
