Chapter 8 Exercise 2 & 3

I get this error message in Jupyter Notebook for excercises 2 & 3:

Exercise
reload(helper.HelperTest)
run(helper.HelperTest.("test_p2pkh_address"))
File "/var/folders/dm/y81m2jm566lcd943x_y5mjsw0000gn/T/ipykernel_34120/4269242462.py", line 4
run(helper.HelperTest.("test_p2pkh_address"))
^
SyntaxError: invalid syntax

Try changing this:
run(helper.HelperTest.("test_p2pkh_address"))
to
run(helper.HelperTest("test_p2pkh_address"))

then I get this error

I'm having a similar problem. If I do this:
run(helper.HelperTest("test_p2pkh_address"))
I get back this:
run(helper.HelperTest.("test_p2pkh_address"))
SyntaxError: invalid syntax

If instead I try:
run(helper.HelperTest("test_p2pkh_address"))
I get back:
ImportError Traceback (most recent call last)

149 if name in _RELOADING:
150 return _RELOADING[name]

ImportError: module HelperTest not in sys.modules

I just managed to do it in exercise 2:
The trick is to also change reload(helper.HelperTest) to reload(helper)
run(helper.HelperTest("test_p2pkh_address"))

This worked! Cheers for the help! 👍
