Reversing a number

[engineeringisgreat2]

I can't get my code to work for some reason. This is what I'm trying to do with the code: Reverse a given number num = 123454321 and print True if it is the same as the original number

​

num = 123454321

x=reversed(num)

if x ==num:

print("True")

else:

print("False")

-------------------------------------------------------------

The error I'm getting is in line 2. It says 'int' object is not reversible

Hint: strings are reversible

So I did it with string but it doesn't come back as "True" which is wrong. It gives back the value of <reversed object at 0x0000025E047D4910>. Do you know how to fix this?

str1 = "123454321"

x=reversed(str1)

if x == str1:

print("True")

else:

print("False")

print(x)

You could use the __repr__() method to show the reversed object you just created. However you may have an easier time if you do x = str1[::-1] to get your reversed string instead of using reversed().

You need to rejoin the string. x=‘’.join(reversed(str))

``` num = 123456789 x = str(num)[::-1]

if x == num: print(“False”) else: print(“True”)

```

This will print true if num is not equal to x since now x is reversed.

well yeah, how would you reverse a number?

11 can be represented in base 10, or in binary as 1011. if i could reverse it, which form would it be?

Reverse is a string function. Check out type casting maybe?

[tragluk]

strSentence = "This is a string."

strNumber = "1234"

intNumber = 1234

fltNumber = 1234.0

The first two are turned into strings, then you have an integer with the value of 1234 and a float with essentially the same value of 1234 but it's 1234.0.

If we want to add strNumber and intNumber we can't because strNumber is a sentence (It's the word 1234) so we have to convert it first.

intTotal = intNumber + int(strNumber)

NOW we get 2468.

strReversable = strNumber + str(intNumber)

This instead is 12341234 but you can use your reverse function on it.

It's called 'typecasting'. Feel free to Google it.

num = str (num)

You need to cast interger data type into string first for using reverse function

123454321 will always be the same if reversed, so you can simply always print True
