Fundamentally no, it's not. Python code will always be distributed as
some form of bytecode. The only way to make it available without
revealing anything is to put it on a server and let people access it
without running it themselves.

But why is that a problem? Copyright law protects you from people
stealing your code and making unauthorized changes to it, and if
you're not worried about them making changes, there's no reason to
hide the source code (whatever you distribute would be just as
copiable). Are you concerned that people will see your bugs? We all
have them.

The OP is asking for source code not to be available, not bytecode.
There are obfuscating tools like PyArmor you might want to have a look at.

The byte code can be decompiled, though, so the attempt to hide the code
