Model $3$ Integers and Floats

Every value in Python has a data type which determines what can be done with the data. Enter the following code, one line at a time, into a Python Shell. Record the output for each line $($if any$)$ in the second column.

Questions:

$18.$ What is the data type $($int$,$ float, or str$)$ of the following values?Note: if you're unsure, use the type function in a Python Shell.$)$

a$)$ pi

c$)$ word

b$)$ integer

d$)$ number

$19.$ List the function calls that convert a value to a new data type.

$20.$ How does the behavior of the operators $(+$and $*)$ depend on the data type?

$21.$ What is the difference between the int function and the round function?

$22.$What is the value of $3+3+3?$ What is the value of $\mathrm{.}3+\mathrm{.}3+\mathrm{.}3?$ If you enter these expressions into a Python Shell, what do you notice about the results?

$23.$ In order to store a number with $100\%$ accuracy, what data type is required? How might you precisely represent a bank account balance of $$123\mathrm{.}45?$

$24.$Try calculating a very large integer in a Python Shell, for example, $123^(456).$ Is there a limit to the integers that Python can handle?

$25.$ Try calculating a very large floating$-$point number in a Python Shell, for example, $123\mathrm{.}0^(465).$Is there a limit to the floating$-$point numbers that Python can handle?

$26.$ Summarize the difference between the numeric data types $($int and float$).$ What are their pros and cons?
