As the world's most widely used programming language, Java is always be compared with zhiPython comparison, and, in a programming language, all kinds of games also played the most warm Python and Java, 1. Java must be explicitly declared variable names, and dynamic type Python does not need to declare a variable, 2. Python is a powerful language syntax is simple, can provide good solution through scripting, and be able to quickly deploy in various fields, 3. Java can create cross-platform application, and Python is compatible with all current operating systems, almost 4. For starters, Python than Java is more easy to use, and the code readability, 5. Speed, Java and Python are not suitable for high performance computing, but on the performance, Java or slightly better, Java efficiency advantage in virtual machine implementation, the program execution, the JVM bytecode can be converted into native machine code, this kind of instant (JIT) compilation for Java performance wins the Python, but Python to fine-tune performance, in order to improve the efficiency of Python! Java and Python are dynamic programming languages, the languages that is associated with openness, so the company, the best team and programmers in the decision remain open, as for, the programmer should choose what kind of programming language, can combine to compare the above five, but more programmers seem more inclined to Python, after all Python in artificial intelligence, data analysis, cloud computing and other fields has better prospects for development!
