Exercise #$1$ While Signs

$($use while loop$($s$))$

You know how to determine if numbers are positive or negative $($we wrote a

program for it before in lecture class$).$ Let's do more things with positive and

negative numbers! You will create a function that distributes numbers entered by

the user into separate lists of positive and nonnegative numbers $($meaning

includes zero and negative numbers$).$ Your program will read numbers from the

keyboard until the user inputs a $\text{'}$q$\text{'}.$

Name your program while$\_$signs.py$.$ Write a function get$\_$positive$\_$negative$()$

that:

$1.$ Repeatedly reads keyboard entries until the user inputs a $\text{'}$q$\text{'}.$ The

prompt should be Input? $($with a single space after the question mark$).$

$2.$ Appends each float input into the appropriate list: positive numbers or

nonnegative numbers

$3.$ Returns the two lists as a tuple, positives first.

For instance:

Input? $34$

Input? $4$

Input? $-7$

Input? $0$

Input? q

$([34\mathrm{.}0,4\mathrm{.}0],[-7\mathrm{.}0])$
