Should I use exit() or just return statements in main() ? Personally I favor the return statements because I feel it's like reading any other function and the flow control when I'm reading the code is smooth (in my opinion). And even if I want to refactor the main() function, having return...
How do I merge two dictionaries in a single expression in Python (taking union of dictionaries)?
...tionaries in a single expression?
For dictionaries x and y, z becomes a shallowly merged dictionary with values from y replacing those from x.
In Python 3.5 or greater:
z = {**x, **y}
In Python 2, (or 3.4 or lower) write a function:
def merge_two_dicts(x, y):
z = x.copy() # start with x's ...

What's the difference between a single precision and double precision floating point operation?
...as the greater data precision available with 64-bit data types is not typically required by 3D games, as well as the fact that processing 64-bit data uses twice as much RAM, cache, and bandwidth, thereby reducing the overall system performance.
From Webopedia:
The term double precision is some...

And try to get rid of B, you have to create an entirely new commit like so:
A-----------C'
Where C' has a different SHA-1 ID. Likewise, ch...

return r - 32
