In fact, it's waiting for you to run it right now!\n",

The only one you really need to learn now, though, is the one on the far left - the *save* icon (or File / Save from the menu).  The IPython Notebook *does not autosave!* - so if you close this webpage down without saving, you'll lose all the work you've done on it!

This can help you remember Python commands, variable names, etc., especially if you can remember the first letter.\n",

A list of possible things you can do to `x` appears (really, they're things `x` can do to *itself* when you tell it to).  Choose the first one, `capitalize`.
