DICTIONARIES telephone numbers (and other numbers that may contain leading zeros) should be represented as strings of digits—not integers. There are keys and values,closed in a curly braces/ >>> phonebook = {'Alice':'1111','Beth':'2222','Cecil':'3333'} >>> phonebook['Cecil'] '3333' ______________________________________________ dict function >>> items = [('GG','FF'),('11',22)] >>> items = dict(items) >>> items {'GG': 'FF', '11': 22} It can be used with keyword arguments >>> d = dict (name = "Gumby", age  = 42) >>> d {'age': 42, 'name': 'Gumby'} _________________________________ BASIC DICTIONARY OPERATIONS >>> d = dict(apple = 'gavno',android = 'fuflo') >>> d {'android': 'fuflo', 'apple': ...

String formatting operator >>> print format % value Hello, Pit, How do you do? >>> format = 'Hello, %s. %s do you do?' >>> values = ('Pit','How') >>> print format % values Hello, Pit.
