How can I add the number and its reverse in Python?

I have to add a number and its reverse without using functions or strings. This is my code:

number = int(input("Enter your number: "))
revs_number = 0
while (number > 0):   
    remainder = number % 10  
    revs_number = (revs_number * 10) + remainder  
    number = number // 10

print("The reverse number is ", revs_number)
print(number + revs_number)

When I run this, the output is:

Enter your number: 56
The reverse number is 65
65

I tried everything I know but I couldn't add these two. I searched this forum too, couldn't find any solution without strings and functions. Can someone help me please? I really want to learn how because this took my time! Thanks in advance.

number = int(input("Enter your number: "))
revs_number = 0
initial_num=number #copy your input, after while loop execution it will be 0

while (number > 0):   
    remainder = number % 10  
    revs_number = (revs_number * 10) + remainder  
    number = number // 10

print(number) #output 0
print("The reverse number is ", revs_number)
print(initial_num + revs_number)

The variable number is being modified in the loop. Assigning this to a new variable would solve this issue like here:

user_input = int(input("Enter your number: "))
number = user_input

revs_number = 0
while (number > 0):   
    remainder = number % 10  
    revs_number = (revs_number * 10) + remainder  
    number = number // 10

print("The reverse number is ", revs_number)
print(user_input + revs_number)

Hope this helps!

Number is 0 at the end of the while loop, you need to store it in a temporary variable

number = int(input("Enter your number: "))
revs_number = 0
tmp = number

while (tmp > 0):
    remainder = tmp % 10
    revs_number = (revs_number * 10) + remainder
    tmp = tmp // 10

print("The reverse number is ", revs_number)
print(number + revs_number)
