How to iterate through two lists in parallel?
...ple with None in the position corresponding to that iterator. You can also set a different fillvalue besides None if you wish. See here for the full story.
Note also that zip and its zip-like brethen can accept an arbitrary number of iterables as arguments. For example,
for num, cheese, color in...
Concept of void pointer in C programming
...nter to point to the location of the unknown data type. The program can be set in such a way to ask the user to inform the type of data and type casting can be performed according to the information inputted by the user. A code snippet is given below.
void funct(void *a, int z)

How to pretty-print a numpy.array without scientific notation and with given precision?
...
You can use set_printoptions to set the precision of the output:
import numpy as np
x=np.random.random(10)
print(x)
# [ 0.07837821 0.48002108 0.41274116 0.82993414 0.77610352 0.1023732

Applicatives compose, monads don't
...\x -> replicate x (const ())]
The length of the returned list must be set in stone before an integer is ever provided, but the correct length of it depends on the integer that's provided. Thus, no correct join function can exist for this type.

When should you use constexpr capability in C++11?
...g good readability and allowing slightly more complex processing than just setting a constant to a number.
It basically provides a good aid to maintainability as it becomes more obvious what you are doing. Take max( a, b ) for example:

Computational complexity of Fibonacci Sequence
I understand Big-O notation, but I don't know how to calculate it for many functions. In particular, I've been trying to figure out the computational complexity of the naive version of the Fibonacci sequence:

You can then seek back, e.g.:
fseek(fp, 0L, SEEK_SET);
or (if seeking to go to the beginning)
rewind(fp);
