How to convert an IPv4 address into a integer in C#?
...igned 32-bit value of the IPv4 address (the catch is, it's in network byte order, so you need to swap it around).
For example, my local google.com is at 64.233.187.99. That's equivalent to:
64*2^24 + 233*2^16 + 187*2^8 + 99
= 1089059683

DataContractSerializer doesn't call my constructor?
...But the XmlSerializer also needs public getter and setter on properties in order to serialize / deserialize.

>>> d.popitem()
('c', 7)
Since the dict doesn't preserve order, by using popitem you get items in an arbitrary (but not strictly random) order from it.
Also keep in mind that popitem removes the key-value pair from dictionary, as stated in the docs.
popitem() is useful to dest...
Step-by-step debugging with IPython

ps: note that an ipdb command takes precedence over python code. So in order to write list(foo) you'd need print list(foo).
Also, if you like the ipython prompt (its emacs and vim modes, history, completions,…) it's easy to get the same for your project since it's based on the python prompt t...
