$7\mathrm{.}18$ Lab training: Unit tests to evaluate your program

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$\_\_==\text{'}\_\_$main$\_\_\text{'}$: 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$\_\_\text{'}$:$.$ 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.
