12) Using the code in question 8: Write the python statement which will remove both the key ‘gpa’ and its value 2.8 from s2

13) True or False? A dictionary is a set of items; each item consists of a colon-separated key and value. Each item is separated from other items using a comma. Dictionaries may contain both simple and complex data types. A dictionary may contain data about a single object. Another dictionary may contain data about multiple objects. Dictionaries may contain lists and lists may contain dictionaries. Dictionaries may also contain other dictionaries. Using Python loops and conditional tests we can precisely access any piece of data contained in a dictionary.

14) True or False? The four methods most commonly used to retrieve data from a dictionary are: post(), key(), value() and item().

8) Write Python code for a function called occurances that takes two arguments str1 and str2, assumed to be strings, and returns a dictionary where the keys are the characters in str2. For each character key, the value associated with that key must be either the string ‘‘none’’, ‘‘once’’, or ‘‘more than once’’, depending on how many times that character occurs in str1. In other words, the function roughly keeps track of how many times each character in str1 occurs...

3.2 Class Dictionary This class implements a dictionary using a hash table in which collisions are resolved using separate chaining. The hash table will store objects of the class Data. You will decide on the size of the table, keeping in mind that the size of the table must be a prime number. A table of size between 5000-10000, should work well. You must design your hash function so that it produces few collisions. A bad hash function that induces...
