Converting JSON String to Dictionary Not List
...you need to use to get the result you want is a list comprehension:
[p[0] for p in datapoints[0:5]]
Here's a simple way to calculate the mean:

Which, if any, C++ compilers do tail-recursion optimization?
...
All current mainstream compilers perform tail call optimisation fairly well (and have done for more than a decade), even for mutually recursive calls such as:

return (n == 0) ? acc : bar(n - 1, acc + 2);
}
