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.

    >>> help(dict)    Help on class dict in module builtins:    class dict(object)     |  dict() -> new empty dictionary     |  dict(mapping) -> new dictionary initialized from a mapping object's     |      (key, value) pairs    ...     |       |  get(...)     |      D.get(k[,d]) -> D[k] if k in D, else d.  d defaults to None.     |      ...


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.
