This article mainly shows you "what is the difference between python and nodejs", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn the "what is the difference between python and nodejs" this article.

The differences between python and nodejs: 1. Python can not directly manage multiple versions of dependent packages, while nodejs can directly use NPM for package management. 2. Python is divided into two major versions: 2 and 3, which have poor compatibility, while the nodejs version and API are more stable and unified. 3. Python lacks the ability to dynamically compile JIT, and node can. 4. The learning cost of node is low.

The operating environment of this tutorial: windows7 system, nodejs 14.15.4&&Python3 version, DELL G3 computer.

Package and module management

Dependent package multi-version management

Python cannot be managed directly, so we need to use virtualenv to divide different environments.

Nodejs NPM package management that can rely on different versions of third-party modules at the same time

Lead-in module

Python uses from / import, so it is difficult to distinguish different modules with the same name.

Other modules introduced by the nodejs module have locally valid names in this module, which is freer, more flexible and more convenient.

Export module

Python

Nodejs can add attributes directly to exports or assign values to module.exports. It is not a language level, but a simple and common operation.

Language itself

Version unity

Python is divided into two large versions, which are not compatible with each other. Many modules need a specific python version, which is quite confusing.

Nodejs version and API are relatively stable and unified, and NPM is compatible with various versions of dependent modules, and the version management is orderly, which well supports the version of node core and third-party modules into llj.

Grammar

Python is indeed quite concise and clear, especially the support of rich data structures, concise various operators instead of functions, it can be said that there are rich syntax sugar.

Nodejs language is javascript, the core is more concise, although its own data structure and data processing are relatively simple, but the use of coffee-script can make up for it. Coffee-script is simply the javascript version of python.

Flexibility

Javascript prototype-based inheritance is more flexible

Nodejs's event-based handling makes hooks and extension points everywhere

Hackability

Python is not easy, hack.

Javascript is very easy to hack.

Performance

They are all interpretive languages.

Python lacks the ability to dynamically compile JIT

Nodejs v8 can execute javascript with JIT for better performance

Concurrent model

Python requires multithreaded programming

Nodejs uses non-blocking asynchronous Istroke O, which is very efficient for non-CPU-intensive applications.

Development quality and efficiency

They are all interpretive languages.

Nodejs has a complete build system (grunt/gulp)

The richness, innovation and activity of nodejs in web development resources are much higher than those of python.

All kinds of checks cannot be carried out during the compilation period.

But nodejs has a variety of format and syntax checkers for the javascript language

Javascript can be developed with coffee-script, which absorbs a lot of python grammar sugar.

Build system

Learning cost

If you only have the energy to learn one language

It must be javascript, because at least the front end of the browser needs js

The js language core is smaller, more refined, and more grammatical sugars and functions are provided through modules or libraries.

Nodejs itself can be used as a production web server, while python at least requires a nginx proxy

Environmental preparation

There is no python environment by default in windows, but you can practice javascript in the debugger console in the browser

It is also not easy to integrate third-party modules cross-platform nodejs supports python in x86/arm/power/sparc due to the extensive use of the cripple cymbal + module, cross-platform is worse than other similar aspects of nodejs
