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 $\_$ name$\_\_==\text{'}\text{'}$: 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 $\_==\text{'}\_$main $\_$ : : 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 $==\text{'}\_$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 $0$ 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 $($Ibs$).$

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 $0$ and the output of the program is:

$22\mathrm{.}040lbs$
