Virtual Desktops rock and you should read this list of new shortcuts before complaining that there are none, like I did. Important ones: * WIN + TAB, new task view opens up and stays open. * WIN + CTRL + D, create new virtual desktop. * WIN + CTRL + F4, close current virtual desktop. * WIN + CTRL + LEFT/RIGHT, switch virtual desktop. Unfortunately, the new start menu doesn't really rock. I suggest you have a look at my suggestion about the Search Everywhere Interface and maybe vote on it.


Member variables in python are horrible. They are not visible in the layout of the class which is instantiated, but instead the __init__ function of a class creates certain member variables for the instance. I have never liked this about python, to be honest. For a recent project, I devised the following solution. Assume you would want this behaviour:
>>> class test(Base):
...     # Variables
...     number = 4
...     string = "hodor"
...     # Functions
...     def stringmult(self):
...         return self.number * self.string
...
>>> test().stringmult()
'hodorhodorhodorhodor'
>>> test(number=2).stringmult()
'hodorhodor'
>>> test(string="Na",number=8).stringmult() + " - Batman!"
'NaNaNaNaNaNaNaNa - Batman!'
>>> 
>>> test(end="Batman!")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ctypes.ArgumentError
>>>
In other words, any class that inherits from Base can be constructed with keyword arguments who must match exactly the correct class variables which you specify. This one does it:
from ctypes import ArgumentError
class Base(object):
    def __init__(self, **kwargs):
        # "given" is the list of keyword arguments passed to the constructor
        # of this object, "needed" is the list of class variables which belong to  
        # the base class of the object which is being created, which do not end 
        # with two underscores and which are not a function. Trust me, we do not 
        # want to meddle with those.
        given = list(kwargs.keys())
        needed = [attr for attr in dir(self.__class__) if attr[-2:] != '__' \
             and type(self.__class__.__dict__[attr])!=type(lambda:0) ]

        # Check if keyword arguments have been provided which are not among the
        # required arguments and throw an exception if so. Remove this check for
        # a less restrictive base class. I wouldn't recommend it.
        if not set(given) <= set(needed):
            raise ArgumentError()

        # First, initialize the attribute dictionary of the object being created
        # with a list of default values, indicated by the values of the class 
        # variables. Then, update the attribute dictionary again with the values
        # provided to this constructor.
        self.__dict__.update({k: self.__class__.__dict__[k] for k in needed})
        self.__dict__.update(kwargs)
I personally like this approach a lot and hereby dare you to tell me even a single reason not to do this, in the comments.
