Error Handling in Python

• Python has built-in support for handling errors cleanly
• Exceptions!
• You 'try' running a block of code, and catch 'except'ions
• An example of an exception was shown earlier

  >>> foo = ('bar', 234, ['a list inside', 'a tuple!'])
  >>> foo[0]
  'bar'
  >>> foo[0] = "watch out, it's immutable"
  Traceback (most recent call last):
    File "<stdin>", line 1, in ?
  TypeError: object doesn't support item assignment
