Compile it to a .pyc file and give that to your users instead of
the .py file.  You can use py_compile or compileall in the Python
standard libraries for this.

Note, however, that this does not protect you from the really
inquisitive or from malicious users and so on.  They could use
dis, for example, from the Python standard library to learn about
your code.
