Will python replace java?
What is the hottest programming language now? Of course it is-Python. Did you know? Even primary school students are starting to learn Python now.
Python has also been making rapid progress in the programming language rankings, jumping to the fourth position. Now besides the old Java, C and C, who else can compete with Python? For example, with the continuous efforts of the masters, Python can now do almost everything, build webs, make crawlers, and engage in AI. Moreover, Python has many libraries, so Python development efficiency is extremely high. In addition, Python can also be used with other languages. A good joint development of two languages (commonly known as the "glue language"), Python is simply an invincible, omnipotent and perfect language style, right?
So will Python surpass Java in the future?
Won't. (Recommended learning: Python video tutorial)
Python is still several blocks away from true perfection? Why do you say that?
First of all, Python does not have an advantage in execution efficiency. Since Python is an interpreted dynamic type language, it is inherently slower in execution speed. Needless to say, it cannot compare with C, and it does not have an advantage even when compared with Java, which has always been weak in speed. This limits the possibility of using Python on some projects that require high execution efficiency.
Secondly, in terms of cross-platform, Python does not have an advantage over Java. Now JVM supports almost all available platforms, and quite a few platforms come with their own JVM. , so Java programs can be used directly on the platform where the JVM is installed, while Python requires a compiler to convert the code written in Python into the code of the specified operating system before it can be used.
Finally, the characteristics of Python determine that it is currently not very suitable for the development and maintenance of large projects. If the first two points may be improved to some extent with the development of Python, then Python is naturally lacking in maintainability. Many people who are new to Python find it very enjoyable to write programs in Python. In the past, when writing codes in C, C and Java, they always felt that they were subject to various constraints. For example, variables must be defined before they can be used, only one variable can be assigned a value at a time, and parameters return values. There can only be one. . . . , but in Python, these are not problems, you can write whatever you want, as if you suddenly took off the shackles and handcuffs when dancing.
However, It is precisely because Python is too free that Python programs have poor maintainability when writing large programs. Java is much better at this point, because Java encourages structurally standardized interface design and concise code relationships, coupled with Dependency Injection, making Java code highly reusable. There is no concept of interface in Python, which results in the lack of precise design of all classes when writing. In addition, new members can be added dynamically, which makes code reuse quite difficult.
So, Python does have quite a few advantages. In addition to some of its own excellent features, its rise also happens to catch up with the current development of technologies such as big data and artificial intelligence. This makes Python’s advantages be It has been enlarged a lot. Of course, it is undeniable that Python still has very good development prospects in the future, but if it can replace Java and reach the top, I am afraid there is still a long way to go.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.

VS Code extensions pose malicious risks, such as hiding malicious code, exploiting vulnerabilities, and masturbating as legitimate extensions. Methods to identify malicious extensions include: checking publishers, reading comments, checking code, and installing with caution. Security measures also include: security awareness, good habits, regular updates and antivirus software.

In VS Code, you can run the program in the terminal through the following steps: Prepare the code and open the integrated terminal to ensure that the code directory is consistent with the terminal working directory. Select the run command according to the programming language (such as Python's python your_file_name.py) to check whether it runs successfully and resolve errors. Use the debugger to improve debugging efficiency.

VS Code can be used to write Python and provides many features that make it an ideal tool for developing Python applications. It allows users to: install Python extensions to get functions such as code completion, syntax highlighting, and debugging. Use the debugger to track code step by step, find and fix errors. Integrate Git for version control. Use code formatting tools to maintain code consistency. Use the Linting tool to spot potential problems ahead of time.

VS Code is available on Mac. It has powerful extensions, Git integration, terminal and debugger, and also offers a wealth of setup options. However, for particularly large projects or highly professional development, VS Code may have performance or functional limitations.

The key to running Jupyter Notebook in VS Code is to ensure that the Python environment is properly configured, understand that the code execution order is consistent with the cell order, and be aware of large files or external libraries that may affect performance. The code completion and debugging functions provided by VS Code can greatly improve coding efficiency and reduce errors.
