And is Java?  They both have a byte code interpreter.

My understanding is Java is both a compiled and interpreted language -
with javac compiling java code to byte code and then JVM interpreting
and executing the byte code.

And then there's the CPython implementation of Python. <snip>
Granted, it has an implicit, cached compilation step, but is it less compiled for that?

I would so no - in my mind compiling analyses the entire source and
then translates it whilst interpreters only explore a single line or
expression. Simply because the compilation happens only Just In Time,
doesn’t make it any less of a compilation step.

Hope that helps,
Silas
