Write a Python $(.$py$)$ file that provides answers to the following questions. Be

sure to organize your code so that each answer is provided in order. Let me

know if you have questions!

Which of the following variable names are legal in Python? For those that are

Assume that you are taking $5$ courses this semester, and that you need to

purchase textbooks for each. Write a short program to calculate the total costs of

your textbooks for the semester. What kind of number is your output?

For each of the following equations, write them out as python code. To double

check whether your code is correct, I have provided test values and the output

that correct code will produce.

$y=8x+5$ where $ifx=5,$ then $y=45$

$j=2(i^2+5)$ where $ifi=5,$ then $j=60$

$d=\frac{(a^2+b^2)}{c}$ where $ifa=2,b=3$&$c=4,$ then $d=3\mathrm{.}25$

$p=mn(m^n-n^m)$ where $ifm=3$&$n=4,$ then $p=204$

Assign the following sentence as a string: My cat's breath smells like catfood.

Using string indexing $([$I$),$ write code that will print the following on the

console:

a$.$ y cat's breath smells like catfood.

b$.$ My cat's breath smells like

c$.$ breath

d$.\text{'}$s
