Go's performance would certainly outstrip Python's by a good margin. Go also has some nice advantages like being able to compile a binary and hand that off and not needing to worry about virtual environments etc
感觉看不出差异,但官方1.8在GC、Compile等方面优化提升了20%,可能是这demo太简单了吧。 2.Python,最近玩得也火热,所以拿来比比 def fibonacci(i): if i<2: return i return fibonacci(i-2) + fibonacci(i-1) print(fibonacci(34)) 1. 2. 3. 4. 5. 6. 先来看看python2.7 qiangjian@localhost:/work...

这个我用pypy 2.7确认了下,确实没那么差, 如果用numpy或其他版本python的话,性能更快。但pypy还不完善,pypy3在beta, 所以一般情况,我是说一般情况下,这点比较让人不爽。
还有权威对比: https://benchmarksgame.alioth.debian.org/u64q/go.html 原文 https://blog.famzah.net/2016/09/10/cpp-vs-python-vs-php-vs-java-vs-others-performance-benchmark-2016-q3/ 大家看看就好。 最后,就是加个大图,说明一切 但是图中没有算compile时间,对动态语言不公平。

In addition to Rust’s ability to deliver on performance, the language goes to great lengths to ensure developers can’t inadvertently introduce something to their programs that would keep it from compiling. If you’re accustomed to languages such as Python or Ruby, this may come across as som...
Go语言没有类似Java或Python那种try...catch...机制处理异常,Go的哲学是与众不同的,Go的设计者认为主流的异常处理机制是一种被过度滥用的技巧,而且存在很大的潜在危害,Go的异常处理(或者说是错误处理)是一种非常简单直观的方式。通常的,我们在写Java、Python之类的代码时,遇到可能存在的异常,直接用try括起来,使用...
这个就像 Python 的一样。 gnuflag - GNU 兼容的标志解析;与flag基本兼容。 go-commander - 使用命令和子命令、参数检查和上下文使用帮助简化 Go 命令行界面的创建。从“go”工具代码分叉。 go-flags - go 的命令行选项解析器 go-getoptions - 受 Perl 的 GetOpt::Long 灵活性启发的 Go 选项解析器. goopt...
Consider utilizing Golang in a company setting with a smaller organizational structure, where the lack of mid-level management improves the speed with which tasks are completed. In addition, Go is quicker than languages likeJavaandPythonin general, which improves service availability and reliability....
