Operations with Lists Inspired by this question.
Given a list containing numbers, print:

The sum and product of the numbers in the list
The average and median
The differences between each term in the list (e.g. [1,2,3] -&gt; [1,1]: 1+1=2, 2+1=3)
The list, sorted ascending
The minimum and maximum of the list
The standard deviation of the list

For reference:
Standard Deviation
$$\sigma=\sqrt{\frac1N\sum^N_{i=1}(x_i-\mu)^2}$$
Where \$\mu\$ is the mean average, \$x_i\$ is the \$i\$th term in the list, and \$N\$ is the length of the list.
Shortest code wins. Good luck!
