Return None if Dictionary key is not available
You can use dict.get()
value = d.get(key)which will return None if key is not in d. You can also provide a different default value that will be returned instead of None:
value = d.get(key, "empty")
Wonder no more. It's built into the language.

Use dict.get
Returns the value for key if key is in the dictionary, else default. If default is not given, it defaults to None, so that this method never raises a KeyError.
