Where is 'palindrome' defined?
Hi, When I search solution of reverse a string/number, I came across a short function online: def palindrome(num): return str(num) == str(num)[::-1] I thought that it is a general function. And with the following variable: a '1234_' parlindrome(a) Traceback (most recent call last): File pyshell#126, line 1, in module parlindrome(a) NameError: name 'parlindrome' is not defined Then, I find that parlindrome is a special checking mirrored word. I use Python 2.7.9. Why does the error message show name 'parlindrome' is not defined Thanks, -- https://mail.python.org/mailman/listinfo/python-list

I thought that it is a general function. And with the following variable:
No, this function is not built into Python because ... Well it's hard
to say why. It's not very general, or not useful to many programmers,
or nobody's thought about it or made a case for including it in Python, etc.
But that should be no problem. You can define it yourself (by entering
the two line you have above). Then it will be defined, and calling
parlindrome('...')
will produce a result rather than an error.

Traceback (most recent call last):
File pyshell#126, line 1, in module
parlindrome(a)
NameError: name 'parlindrome' is not defined
Then, I find that parlindrome is a special checking mirrored word.
I use Python 2.7.9. Why does the error message show
name 'parlindrome' is not defined

Re: Where is 'palindrome' defined?
Hi, Because palindrome != parlindrome? Have you read the error message? Did you try to understand it?

When you are starting with any new thing, even the simplest problems look baffling. Once you have achieved a few successes, such error messages start to make sense. I didn't intend to be harsh. Sorry if I failed. Anyway, for me the errors provided by python are mostly very useful. When I forget to read them, or I'm simply too impatient to try to understand them, I use to get very hard debugging sessions. The contrary is often true. What I tried to emphasize is the importance of paying careful attention to the error messages. It is a good habit to start doing this from the beginning.

The computer is not psychic yet, so it doesn't know that when you wrote pa_r_lindrome you meant palindrome, you have to spell it the same way every time for the computer to recognise that you mean the same name. Now you also know that the error message: NameError: name 'something' is not defined means that you might have spelled something differently on the line in the error message to the word you meant, so next time you see this error message you know to carefully check the spellings of function names and variables. -- Denis McMahon, denismfmcma...@gmail.com -- https://mail.python.org/mailman/listinfo/python-list

It compares 'num' as a string to the reverse of that to test whether it's a palindrome, so, yes, it's behaving correctly.
