$20.$ Add a Test Case

Look at the test script test.py$.$ You can see that there is space for an additional test case in the test procedure test$\_$avg. We want you to test the function on range$(10,20).$ To do this:

Create a tuple for range$(10,20)$ by calling the function and converting it to a tuple.

Pass this tuple to avg using tuple expansion.

Once you have done this, run the test script again to make sure you pass the new test.

def test$\_$avg$()$:

$"""$

Test procedure for function avg$().$

$"""$

print$(\text{'}$Testing avg$()\text{'})$

result $=$ func.avg$()$

introcs.assert$\_$floats$\_$equal$(0,$result$)$

result $=$ func.avg$(7,1,4,3,6,8)$

introcs.assert$\_$floats$\_$equal$(4\mathrm{.}833333333333333,$result$)$

result $=$ func.avg$(-1,1,3,5)$

introcs.assert$\_$floats$\_$equal$(2\mathrm{.}0,$result$)$

result $=$ func.avg$(2\mathrm{.}5)$

introcs.assert$\_$floats$\_$equal$(2\mathrm{.}5,$result$)$

result $=$ func.avg$(1\mathrm{.}0,1\mathrm{.}0,1\mathrm{.}0)$

introcs.assert$\_$floats$\_$equal$(1\mathrm{.}0,$result$)$

# Test range$(10,20)$ here
