Python vs. Java Performance
Python and Java are two of the most popular and robust programming languages. Java is generally faster and more efficient than Python because it is a compiled language. As an interpreted language, Python has simpler, more concise syntax than Java. It can perform the same function as Java in fewer lines of code.

Speed and efficiency differences between Python vs. Java

Java’s efficiency largely comes from its Just-In-Time (JIT) compiler and support for concurrency. The JIT compiler is a part of the Java Runtime Environment. It improves performance of Java programs by compiling bytecodes into native machine code “just in time” to run. Java Virtual Machine (JVM) calls the compiled code directly. Since the code is not interpreted, compiling does not require processor time and memory usage. Theoretically, this can make a Java program as fast as a native application.
