Python (CPython Runtime):
– Python source code (.py) is compiled into bytecode automatically in memory.
– Bytecode can also be cached in .pyc files, making re-runs faster by using the cached version.
– The Import System loads modules and dependencies.
– The Python Virtual Machine (PVM) interprets the bytecode line by line, making Python flexible but relatively slower.
Java (JVM Runtime):
– Java source code (.java) is compiled into .class bytecode using javac.
– The Class Loader loads bytecode into the Java Runtime Environment (JVM).
– Bytecode is verified and executed.
– JVM uses both an Interpreter and a JIT Compiler, frequently used code (hot paths) is converted into native machine code, making Java faster.
Over to you: Do you prefer the flexibility of Python or the performance consistency of Java?
