IN PYTHON PLEASE

Auto$-$graded programming assignments may use a Unit test to test small parts of a program. Unlike a Compare output test, which evaluates

your program's output for specific input values, a Unit test evaluates individual functions to determines if each function:

is named correctly and has the correct parameters and return type

calculates and returns the correct value $($or prints the correct output$)$

The zyLabs auto$-$grader runs

main.py as a script. In

main.py$,$ the line if $==\text{'}\text{'}$ : is used to separate the main code

from the functions' code so that each function can be unit tested. Enter statements to be run as the main code under if

name

$==$

$\text{'}\_\_\_$mair $\text{'}$ : Indent the statements so the statements belong to the if block. Refer to the subsection Importing modules and executing

scripts under section Module basics for more information about running a program as a script.

Note: Do not remove if

name

$==$

main

$\text{'}$ : from the code. Otherwise, the unit tests will fail even though the program

produces the correct output.

This example lab uses multiple unit tests to test the kilo$\_$to$\_$pounds$()$ function.

Complete a program that takes a weight in kilograms as input, converts the weight to pounds, and then outputs the weight in pounds. $1$

kilogram $=2\mathrm{.}204$ pounds $($lbs$).$

The program must define the following function:

def kilo$\_$to$\_$pounds$($kilos$)-$ take kilos as a parameter, convert kilos from kilograms to pounds, and return the weight in pounds.

Ex: If the input of the program is:

$10$

$10$ is passed to kilo$\_$to$\_$pounds$()$ and the output of the program is:

$22\mathrm{.}040lbs$

The program below has an error in the kilo$\_$to$\_$pounds$()$ function.

Try submitting the program for grading $($click "Submit mode", then "Submit for grading"$).$ Notice that the first two test cases fail, but

the third test case passes. The first test case fails because the program outputs the result from the kilo$\_$to$\_$pounds$()$ function, which

has an error. The second test case uses a Unit test to test the kilo$\_$to$\_$pounds$()$ function, which fails.

Change the kilo$\_$to$\_$pounds$()$ function to multiply the variable kilos by $2\mathrm{.}204,$ instead of dividing. The return statement should be:

return $($kilos $*2\mathrm{.}204).$ Submit again. Now the test cases should all pass.

Note: A common error is to mistype a function name with the incorrect capitalization. Function names are case sensitive$,$ so if a lab

program asks for a kilo$\_$to$\_$pounds$()$ function, a kilo$\_$To$\_$Pounds$()$ function that works for you in "Develop mode" will result in a failed unit

test. The unit test will not be able to find kilo$\_$to$\_$pounds$().$def kilo$\_$to$\_$pounds$($kilos$)$:

return kilos $*2\mathrm{.}204$

if $\_\_$name$\_\_==\text{'}\_\_$main$\_\_\text{'}$:

kilos $=$ float$($input$())$

pounds $=$ kilo$\_$to$\_$pounds$($kilos$)$

print$($pounds$,"$lbs$")$
