Write a Python script to calculate the average and standard deviation of the following set of numbers:

$1.$ x $=\{1\mathrm{.}0,1\mathrm{.}2,1\mathrm{.}2,0\mathrm{.}9,1\mathrm{.}1,0\mathrm{.}8,0\mathrm{.}7,1\mathrm{.}1\}$

$2.$ x $=\{5\mathrm{.}6,6\mathrm{.}1,7\mathrm{.}1,7\mathrm{.}9,5\mathrm{.}1,6\mathrm{.}0,5\mathrm{.}3,6\mathrm{.}3\}$

The average is defined as:

x$=1/$n Xn i$=1$ xi

where n is the number of elements in the set of numbers.
