Python and Java are two of the most popular and widely used languages in programming. While both function as programming languages, they have distinct features and differences.

This makes it important for programmers to understand the difference between Java and Python to help them make informed decisions. Below are the key differences between Python vs Java:


Below is a comparison of the difference between Python vs Java in terms of typing:


Python is dynamically typed. This means the variable type is determined at runtime, not in advance. This leads to a smoother and faster coding process since you don’t have to declare the variable type when you write the code. This can also sometimes lead to runtime errors if data of the wrong type is assigned to a variable or used in an operation.


Java is statically typed. Every variable must be declared with its data type before it can be used, and once declared, its data type can’t be altered. While this can generate a slightly more verbose coding process, it allows errors to be caught at the compile time, helping ensure that type-related errors are reduced during runtime.

Code Readability & Formatting

Below is a comparison of the difference between Python vs Java in terms of code readability and formatting:


Python places a significant emphasis on code readability. It employs a clear and concise syntax, so it’s often recommended for beginners. Using indentation to define code blocks ensures that Python code is clean and easily readable. This characteristic is encapsulated in the Zen of Python, which states, among other things, ‘Readability counts.’


Java, while powerful, tends to be more verbose than Python. This means that Java often requires more lines of code for the same functionality. Java uses braces {} to define the beginning and end of each function and class definition, which can lead to the ‘pyramid of doom’ due to deep nesting. Java’s clear structure and object-oriented nature mean that with good coding practices, Java code can be highly readable.


Below is a comparison of the Python vs Java performance difference:


Python is an interpreted language, which generally means it is slower than compiled languages. While Python code is more straightforward to write and read, this simplicity comes at the cost of performance. The difference in speed isn’t always prominent for small to medium-sized applications, and Python offers several tools and libraries to accelerate code execution.


Java is compiled to bytecode and runs on the Java Virtual Machine (JVM). This allows Java to be platform-independent while leveraging compiled languages’ speed advantage. Java is faster in execution than Python. Its performance can also be enhanced using Just-In-Time (JIT) compilers and several optimizations offered by the JVM.


Below is a comparison of the difference between Python vs Java in terms of portability:


Python code is highly portable. You can run a Python script on any operating system with the appropriate environment setup. This portability relies heavily on the Python interpreter. If a system doesn’t have the required interpreter installed, then the Python code cannot run.

Java achieves portability through its Java Virtual Machine (JVM). Once you compile your Java code, it gets converted to bytecode, which can then be executed by the JVM on any platform without modification. This means as long as a platform has a JVM implementation, Java applications can run effortlessly, making it highly portable.


Below is a comparison of the difference between Python vs Java in terms of security:


Python is generally considered secure, but it’s not without its vulnerabilities. The open-source nature of Python means that the community often identifies and patches security flaws rapidly. Many of Python’s security vulnerabilities come from third-party packages or when integrating with external systems. Developers must stay updated with the latest versions and be cautious of the packages they use.


Java has a solid security framework, especially within its runtime environment. The JVM plays a major role in providing a security manager and bytecode verifier. The language itself has various built-in security features, such as bytecode checking and runtime security checks.
