I want to get list of files (actually number of files) in a path, recursively, excluding certain types: The 'get' lets you treat a class method, as if it were a simple property in an object. If you leave off the 'get', you can still access the value by calling. area () instead of just. area

You should call it just once, assign the result to a variable and then, at any point in the future, get any value you Ò€¦ Ultimately it probably doesn't have a safe. get method because a dict is an associative collection (values are associated with names) where it is inefficient to check if a key is present (and return its value) Ò€¦ Here the get method finds a key entry for 'e' and finds its value which is 1. We add this to the other 1 in characters. get (character, 0) + 1 and get 2 as result.
