Python Program To Reverse the Given Number | RRTutors
Published January 07, 2021 In this program we will write a python program to revese the given number.
We can reverse a number in python by belwo ways
- Using for-loop
- Using while-loop
Using for-loop
|
x=(input("Enter a Number: x= "))
revstr=[]
ran = len(x)
for element in reversed(range(0, ran)):
revstr.append(x[element])
rev="".join(revstr)
print(rev)
|
Using while-loop
|
n=int(input("Enter number: "))
rev=0
while(n>0):
dig=n%10
rev=rev*10+dig
n=n//10
print("Reverse of the number:",rev)
|
Output:
|
Enter number: 126758
Reverse of the number: 857621

- Take input from user and store it in a variable n.
- By using the while loop we obtained last character by using modulus operator
- The last digit will stored at one’s place, next second is at the ten’s place and so on.
- The last digit is then removed by truly dividing the number with 10.
- Then While loop will return when the value of the number is 0.
- Finally revere of the given number will return
