How to remove a key from a Python dictionary?
...oring the return value of a function is not inefficient at all. Quite the opposite – this solution is much faster than the try/except solution if the key does not exist. You might find one or the other easier to read, which is fine. Both are idiomatic Python, so choose whatever you prefer. But...

... network or stored in a persistent storage.
Deserialization is the exact opposite - Fetch a stream of bytes from network or persistence storage and convert it back to the Object with the same state.
The thing to understand is how those stream of bytes are interpreted or manipulated so that we get...

...his same problem. Here's how I solved it in Arch.
find /usr/lib/python2.7/site-packages -maxdepth 2 -name __init__.py | xargs pacman -Qo | grep 'No package'

...ostly in .NET is actually untrue and in the case of simple types the exact opposite.
int len = somearray.Length;
for(i = 0; i < len; i++)
{
