And Boolean AND x and y returns False if x is False, else it returns evaluation of y or Boolean OR If x is True, it returns x = True; y = True, else it returns eval- False; x or y reuation of y turns True. Short-circuit evaluation applies here as well. x = False; y = True; x and y returns False since x is False. In this case, Python will not evaluate y since it knows that the value of the expression will has to be false (since x is False). This is called short-circuit evaluation. Operator Precedence If you had an expression such as 2 + 3 * 4, is the addition done first or the multiplication?

The dictionaries that you will be using are instances/objects of the dict class. 4. org How It Works We create the dictionary ab using the notation already discussed. We then access key/value pairs by specifying the key using the indexing operator as discussed in the context of lists and tuples. Observe that the syntax is very simple for dictionaries as well. We can add new key/value pairs by simply using the indexing operator to access a key and assign that value, as we have done for Guido in the above case.
