Model $1$ Python Calculator

In a Python Shell window, $>>>"$ is a prompt indicating that the interpreter is waiting for input.

All text entered after the prompt will be executed immediately as Python code.

If you type a Python expression $($code that results in a value$)$ after the prompt, Python will

show the value of that expression, similar to a calculator. You can use Python's math module to

perform more complex mathematical operations like logarithms and trigonometric operations.

Questions:

$1.$ In the middle "Predicted output" column, write what value you expect will be displayed, based on your team's experience using a calculator. If there are any lines you are not confident about, place an asterisk next to your predicted output.

$2.$ Open a Python Shell on your computer. Type each Python expression at the prompt, one

line at a time, and write the corresponding Python output in the third column above. If an error occurs, write what type of error it was $($i$.$e$.,$ the first word of the last line of the error message$).$

$3.$ What does the $**$ operator do$?$

$4.$ Based on the Python code in Model $1,$ identify four examples of:

a$)$ mathematical operator

b$)$ mathematical function

$5.$ For addition and multiplication to produce an output with a decimal value, what type of number must be part of the input? Provide justification for your answer.

$6.$ Does division follow the same rule as in #$5?$ Provide justification for your team's answer.

$7.$ The output of Model $1$ displayed three different errors. Explain the reason for each:

a$)$ TypeError

b$)1$st NameError

c$)2$nd NameError

$8.$ Identify two differences between using a Python built$-$in function $($e$.$g$.,$ abs$)$ and a function from the math module.
