Sum a list of numbers in Python
...
Question 2:
That use of sum should work fine. The following works:
a = range(10)
# [0,1,2,3,4,5,6,7,8,9]
b = sum(a)
print b
# Prints 45
Also, you don't need to assign everything to a variable at every step along the way. print sum(a) works just fine.

How to convert vector to array
... vector():start_(0), finish_(0), end_of_storage_(0){}
//......
}
The range (start_, end_of_storage_) is all the array memory the vector allocate;
The range(start_, finish_) is all the array memory the vector used;
The range(finish_, end_of_storage_) is the backup array memory.
For example, ...

Difference between decimal, float and double in .NET?
...-8, while decimal will conflate 0.1 and 0.1 + 1e-29. Sure, within a given range, certain values can be represented in any format with zero loss of accuracy (e.g. float can store any integer up to 1.6e7 with zero loss of accuracy) -- but that's still not infinite accuracy.

How do I build a numpy array from a generator?
...generator with numpy.stack:
>>> mygen = (np.ones((5, 3)) for _ in range(10))
>>> x = numpy.stack(mygen)

(10, 5, 3)
It also works for 1D arrays:
