Error handling code

You can deal with errors by using 'try' and 'except' like Java or other languages. There is a simple program:

try:    n = input('Type some number.')    for i in [10.,20.,30.]:      print i/n except:    print 'An error has occurred.'

When you input zero, the program executes the command in 'except' section.
