Chr (), UNICHR () and Ord ()The CHR () function returns a corresponding character by using an integer (that is, 0~255) within range (256) as a parameter. UNICHR () is just like it, except that the Unicode character is returned, and the parameter range of the UNICHR () added from Python 2.0 depends on how your Python is compiled. If it is configured to USC2 Unicode, then it is allowed to range (65536) or 0X0

Article excerpt from: http://www.jb51.net/article/16100.htm1) The first step in learning Python is to download a Python version on the www.python.org website right away.

My experience is that it's easier to learn and teach Python by example than by using the same approach as Ruby or Perl, because Pytho
