To become a Python programmer, start by learning the basics like variables, loops, and functions. Set up Python on your computer and practice simple programs. Gradually explore libraries such as NumPy, Pandas, or Django based on your interest. Work on small projects to build experience, join coding communities, and create a GitHub portfolio. With practice and real-world projects, you can confidently apply for Python-related jobs or freelance work.

Java is considered platform-independent because Java programs are not directly compiled into machine code (which depends on a specific operating system like Windows, Mac, or Linux). Instead: 1. Java code (.java files) is first compiled by the Java Compiler (javac) into an intermediate form called Bytecode (.class files). 2. This Bytecode is not dependent on any specific platform. It can be executed on any system that has the Java Virtual Machine (JVM). 3. JVM is platform-dependent — there are different JVMs for Windows, Linux, Mac, etc., but all can run the same Bytecode because the JVM acts as an interpreter between the Bytecode and the underlying operating system. Simple Diagram Explanation: [Your Java Code] | (javac) | [Bytecode (.class)] | (JVM on any OS) | [Machine-specific code executed]

Because it use JVM and the role of jvm is run the .class file every where that why it is platform independent.
