代码如下:

#encoding=utf-8

print '中国'

#在Python的搜索路径中寻找文件

import sys,os

class Error(Exception):pass

def _find(pathname, matchFunc=os.path.isfile):
    for dirname in sys.path:
        candidate = os.path.join(dirname, pathname)
        print candidate
        if matchFunc(candidate):
            return candidate
    raise Error("Can't find it")

def findFile(pathname):
    return _find(pathname)
def findDir(path):
    return _find(path,os.path.isdir)

print findFile(r'_bsddb.pyd')

打印结果如下：
