My code that checks if a given number is palindrome or not doesn't work

Question

var1 = int(input("enter a number:"))
num = str(var1)[::-1]

if var1 == num:
    print("its a palindrome")
else:
    print("its not a palindrome")

enter a number:121 ---> expected "its a palindrome"

its not a palindrome

enter a number:123 its not a palindrome

Why doesn't the code work in the first example?

Answer 1

While comparing, convert var1 to string:

var1 = int(input("enter a number:"))
num = str(var1)[::-1]

if str(var1) == num:
    print("its a palindrome")
else:
    print("its not a palindrome")

Answer 2

try this,

1. Convert the number to string format using str() function.
2. Using string slicing, reverse the number.
3. Check if the reversed number matches the original number.

num = int(input("Enter number : " ))
reverse = int(str(num)[::-1])

if num == reverse:
   print("Palindrome")
else:
   print("Not Palindrome")

Answer 3

Because the variable types are not the same:

var1 = int(input("enter a number:"))
num = str(var1)[::-1]
var2 = int(num)

if var1 == var2:
    print("its a palindrome")
else:
    print("its not a palindrome")

you need convert to integer type, or:

var1 = input("enter a number:")
var2 = var1[::-1]
if var1 == var2:
    print("its a palindrome")
else:
    print("its not a palindrome")
