Table $1$ shows the orbital period $T($the independent variable$)$ and semi$-$major axis $a($the deper,dent variable$)$ for som from the Kepler mission. Let's say that we want to calculate $T^2$ for every period in the table. When making repetitive ca make use of arrays as outlined above.

PL Q$1.$ Define an array $T$ for the orbital period and fill it with your data by completing the code below. Each data separated by a comma. Don't forget to run the cell when you are finished.

$[]T=$ np$.$array$(["$period $1",$ "period $2",$ "period $3","$ dotsdots $])$

Now, we will define a new array T$\_$squared and populate it with $T^2$ values. Recall from Pre$-$Lab $1$ that to designate an the "double asterisk" operator ${?}^{******},$ NOT the $^$ opera$$or$.$

$[]$ T$\_$squared $=T****2$

print$(T\_$squared$)$

PL Q$2.$ Repeat the steps above to create a separate array for the semi$-$major axis data in the code below. Use your calculate $a^3$ for each data point.

$[]a=np.$array $(["$axis $1",$ "axis $2",$ "axis $3","....."])$

a$\_$cubed $=$ "Write equation here"

print $($a$\_$cubed$)$
