[Tutor] Why do I not get an error when I mistakenly type "humdrum.sigh_strenght" instead of the correct "humdrum.sigh_strength"?

One thing I was unaware of:

"_single_leading_underscore : weak "internal use" indicator. E.g. from
M import * does not import objects whose name starts with an
underscore."

My current understanding is to avoid "from M import *", but it is good
to know that this style of import will not capture names of the form
"_name".
