 Many times it happens that we want to add more data to a value in a dictionary and if the key does not exists then we add some default value. You can do this efficiently using *dict.setdefault(key, default)*.

+If you just do a `for` loop over a dictionary, it will provide you all the available keys in the dictionary.

 If you want to loop through a list (or any sequence) and get iteration number at the same time you have to use *enumerate()*.
