Re: String formatting strangeness

The argument to string format expression needs to be a tuple not a list. Also, all the string escaping makes this very hard to read. You can mix single and double quotes to achieve: print '\t\t\t\n' % \ (number, name, seconds // 60, seconds % 60) which IMHO is much easier to read. Larry
