You are being vague and confusing.  There is no default "_md5" python
library in the standard library.  You should be either using "import
md5" (deprecated) or "import hashlib".  Unless perhaps the code you
show is from inside one of those libraries, and there is a _md5.so
that it uses but cant find.  Not sure about that.

Did you write the code above?  Or did you find it inside another
file?  If you found it inside another file what is the file?

If you still have questions, I have another approach.  Please cover
your palm and fingers with a thick layer of black ink (making sure to
cover your entire hand).  Press your hand down firmly on a piece of
bright white paper.  Allow the ink to dry.  Finally, scan the page and
post it here.  I will attempt to read your palm to find the answer.
