Ian has given you a good answer.  But since you mention java, I'd like
to point out a few things that are different between the two
environments.  He and I are describing CPython;  jython and other
implementations don't use .pyc files, and they behave differently.

java has available a "runtime" environment, for those who don't want or
need the compiler.  CPython comes with the compiler and the runtime
bundled together.

Java's classfile remains stable over a number of compiler versions,
while CPython doesn't seem to worry about that.

Java's classfile has been targeted by a number of other byte code
compilers, including jython.  Code from any of those libraries may use
the java libraries.

With java, one has to explicitly compile the java code, while with
CPython, the runtime logic compiles imported modules if they're not
already compiled.
