How to overload std::swap()
...phase lookup" for templates.

Avoiding if statement inside a for loop?

}
This code is not perfect but you get the idea.
In old C++98 it looks like this:
#include <iostream>
#include <vector>

out << i << '\t'...

The regex will match 1.34, 7.98, 1.2, .3 and .4.
To validate that a given input is a number and nothing but a number, "snap" the expression to the start and end of the input by wrapping it in anchor tags...

Named colors in matplotlib

plt.plot([1,2], lw=4, c='#8f9805')
This is more similar to specifying and RGB tuple rather than a named color (apart from the fact that the hex code is passed as a string), and I will not include an image of the 16 million colors you can choose from.....
