是一个“真实的” C-Python可能吗？ [英] Is a "real" C-Python possible?
问题描述
我理解标准的Python发行版被认为是C-Python的
。 Howerver，目前的C-Python实际上是C和Python实现的组合。 Windows版本的Python发行版中包含大约2000个Python文件
。我不确定
在C中实现了多少C-Python，但我认为在C中实现的模块越多，性能越好，内存越低<它将获得
足迹。
我想知道是否有可能完全（或在
$ b）使用Python就像在PHP中实现的一样，大多数情况下是$ b，就像PHP一样 - 我认为
这就是PHP获得性能优势的地方。或许我错了
，因为重要的核心模块已经在C和那些Python
文件中真的是一个思考包装器。无论如何，如果Python
具有类似于Java的性能，两者都是解释语言，那将是理想的。

证明它。 ;-)
严重的是，切换到更多的C代码会导致开发陷入困境，因为Python比C语言更容易编写。

你能否提供一些证据表明Python比Java或PHP慢？

用C编写所有内容可能是可能的 - 但这是一项艰巨的任务。不是
结果合理。无论标准库在何处使用，都可以使用Python的灵活性，但是，如果确实有任何
的性能提升，那将是值得怀疑的。
但真正值得怀疑的是所谓的性能优势 -
你如何支持它？根据众所周知的（肯定是有限的）计算机语言枪战

Python比PHP快大约25％。当然，这只是一个
基准，与现实生活相关性有问题。但是你从哪里得到
那个PHP的印象比Python更快？

证明一下。 ;-)
我想这是主观的:) - 这就是我的经验感觉
开发的Web应用程序Python和PHP。我无法在网上找到直接的比较。
说真的，切换到更多的C代码会导致开发陷入困境
因为Python比C更容易编写。
我明白。用Python实现的Python模块 - 这就是如何使用Python获得真正丰富的库。

我认为你可以在网上找到的大多数Java-Python基准测试表明，Java的速度要快3到10倍。一些在这里：

这是一篇显示新版本的文章在某些方面，Ruby比Python快了
（他们正在追赶:)

I understand that the standard Python distribution is considered
the C-Python. Howerver, the current C-Python is really a combination
of C and Python implementation. There are about 2000 Python files
included in the Windows version of Python distribution. I''m not sure
how much of the C-Python is implemented in C but I think the more
modules implemented in C, the better performance and lower memory
footprint it will get.
I wonder if it''s possible to have a Python that''s completely (or at
least for the most part) implemented in C, just like PHP - I think
this is where PHP gets its performance advantage. Or maybe I''m wrong
because the core modules that matter are already in C and those Python
files are really a think wrapper. Anyhow, if would be ideal if Python
has performance similar to Java, with both being interpreted languages.

justified by the results. And wherever the standard libraries make use
of the flexibility of Python, it''s questionable if there really was any
performance gain at all.
But what REALLY is questionable is the alleged performance advantage -
how do you back that up? According to the well-known (and surely
limited) computer language shootout
http://shootout.alioth.debian.org/gp...t=all&lang=all
Python is roughly 25% faster than PHP. Granted, this is just one
benchmark, with questionable real-life relevance. But where do you get
the impression from that PHP is faster than Python then?

Prove it. ;-)I guess this is subjective :) - that''s what I felt in my experience
with web applications developed in Python and PHP. I wasn''t able to
find a direct comparison online.
Seriously, switching to more C code will cause development to bog down
because Python is so much easier to write than C.I understand. Python modules implemented in Python - this is how
Python gets its really rich library.

because the core modules that matter are already in C and those Python

has performance similar to Java, with both being interpreted languages.
Could you provide some evidence that Python is slower than Java or PHP?I think most Java-Python benchmarks you can find online will indicate
that Java is a 3-10 times faster. A few here:

Here''s an article that shows the new version of Ruby is
faster than Python in some aspects (they are catching up :)
