The method client.getresponse() retrieves an object which contains our response code, the reason for the code, and other methods to retrieve the body of the Web page we requested. We want to make sure the page returned a 200 message, which indicates that everything executed successfully. ...
In Python, this is all automatic—running the expression creates the entire nested object structure for us. In fact, this is one of the main benefits of scripting languages like Python. Just as importantly, in a lower-level language we would have to be careful to clean up all of the ...
class Matter(object): pass lump = Matter()You can initialize a (minimal) working state machine bound to the model lump like this:from transitions import Machine machine = Machine(model=lump, states=['solid', 'liquid', 'gas', 'plasma'], initial='solid') # Lump now has a new state ...
There are two possible ways of matching on object attributes: by position like Point(1, 2), and by name like Point(x=1, y=2). These two can be combined, but positional match cannot follow a match by name. Each item in a class pattern can be an arbitrary pattern. A simple example...
