Try Except

- ```python
  try:
      # Use "raise" to raise an error
      raise IndexError("This is an index error")
  except IndexError as e:
      pass    # Pass is just a no-op. Usually you would do recovery here.
  except (TypeError, NameError):
  	pass    # Multiple exceptions can be handled together, if required.
  else:   # Optional clause to the try/except block. Must follow all except blocks
  	print "All good!"   # Runs only if the code in try raises no exceptions
  finally: #  Execute under all circumstances
  	print "We can clean up resources here"
  ```
