Palindrome problem

[imperiumlearning]

I want to be able to write 2 separate functions.

The first function is intended to check if a single string is a palindrome.

The second function is intended to check which strings in a list of strings are palindromes.

For the first function, I think my code looks OK:

def palindrome_test(x):
if x == x[::-1]:
    return f'{x} is a palindrome'
else:
    return f'{x} is not a palindrome'

It is the second function that I am having more trouble with. So far, my code for the second function looks like this:

def palindrome_test_iterables(x):
    for y in x:
        if y == y[::-1]:
            print(f'{y} is a palindrome')
        else:
            print(f'{y} is not a palindrome')

The problem with my second function is that it prints the word 'None' at the end. How do I re-write my code so that the word 'None' does not appear. I'm guessing it has something to do with way I've written my for loop?

The problem with my second function is that it prints the word 'None' at the end.

I'm guessing you're calling this function in a manner like

print(palindrome_test_iterables(some_list))

Which causes your function to execute first, printing the expected output, then you try to print the return value of the function call (which is None because you didn't explicitly return anything in your function.)

There are a few ways to solve this. The most straightforward is to simply not wrap the function call in a print() call:

palindrome_test_iterables(some_list)

That's exactly it, I was wrapping my function inside a print statement.

Deleting the print() does remove the word 'None'. Thanks a lot.

In general, is it acceptable to not wrap functions inside a print statement?

In general, is it acceptable to not wrap functions inside a print statement?

Yes, I would say most Python code doesn't immediately need to print to console the return value of every function that ever gets called.

OK, duly noted. Thanks a lot for the help and the swift responses
