python转c工具shedskin_【Python工具】shedskin 把Python翻译成C++

Shed Skin is an experimental Python-to-C++ compiler designed to speed up the execution of computation-intensive Python programs. It converts programs written in a static subset of Python to C++. The C++ code can be compiled to executable code, which can be run either as a standalone program or as an extension module easily imported and used in a regular Python program. 其还支持在Python里嵌入C++代码，并一起编译打包。附件为其详细文档。

以下是一个例子，通过Python求最大子数组之和：

#encoding:utf-8def get_max_sub_array_sum(L):

maxN=L[0]

sN=L[0]

for x in L[1:]:

if sN<0:

sN=0

sN+=x

if sN>maxN:

maxN=sN

return maxNif __name__ == '__main__':

L=[1,2,3,-2]

print get_max_sub_array_sum(L)

L=[1,2,3,-2,1]

print get_max_sub_array_sum(L)

L=[1,2,3,-2,3]

print get_max_sub_array_sum(L) 首先安装shedskin, http://code.google.com/p/shedskin/ 在所在目录执行： >shedskin

max_sub_array_sum 结果为在当前目录下生成3个文件，cpp, hpp和Makefile，接着>make 即生成了一个可执行文件，enjoy it!
