Trouple with elinux guide - RPi Email IP On Boot Debian

I'm having problems getting this python script working on my Wheezy Debian RPi.

http://elinux.org/RPi_Email_IP_On_Boot_Debian

I keep getting the following error message

Code: Select all

SyntaxError: Non-ASCII character '\xc2' in file /home/******/code/ip_mailer.py on line 22, but no encoding declared;

I've copy & pasted the code exaclty as it is on that page, but I keep getting error messages when I try to execute the script - FYI I've not done all the messing about with boot.rc yet. I just wanted to make sure the script works before I do that.

I'm entirely new to Python, but I figured I couldn't go wrong with a copy & paste from a site like this one - obviously I was wrong LOL. Any ideas what the problem is?

The line in question appears to be -

Code: Select all

my_ip = 'Your ip is %s' %  ipaddr


I've tried removing the % ipaddr form the end of this line & that clears up the problem, but then I get the same error code on line 24. Removing the similar part of line 24 after the second % also gets rid of that error. But then I'm left with a useless script that doesn't pass any useful info to an email

Somehow an strange character has appeared in your file. Edit the file and put back the stuff you erased, but verify that there are no non-printing characters in the lines where you get the errors by deleting then re-entering the space characters and verify there is nothing after the last printing character by deleting until the next line joins with the current line, then re-enter the new-line character.

Then try running the program again.

Well that's awesome! Worked like a charm - though I don't know how the erroneous characters appear in the first place

Thankyou for a speedy & helpful reply!

cutting and pasting code from web pages can often bring with it unicode or UTF-8 (non-ascii) characters.
You get similiar problems from word.

Is there a safe way to copy code from a webpage then, without producing these non-ASCII characters?

I mean other than typing it all out myself, obviously!
