这里以在windows下搜索并启动QQ为例，我先把开始菜单、桌面和快速启动栏找了一遍，这样能缩短查找时间。如果找不到再到每个分区中查找。

import osdisk=['D','E','F','G','H']def search_file(filename,search_path,pathsep=os.pathsep):    for path in search_path.split(pathsep):        candidate = os.path.join(path,filename)        if os.path.isfile(candidate):            return os.path.abspath(candidate)if __name__=='__main__':    found=False    for i in os.walk('C:\ProgramData\Microsoft\Windows\Start Menu\Programs'):        search_path=i[0]        find_file=search_file('腾讯QQ.lnk',search_path)        if find_file:            os.startfile(find_file)            found=True    if not found:        for i in os.walk('C:\Users\Jack\Desktop'):            search_path=i[0]            find_file=search_file('QQ.exe.lnk',search_path)            if find_file:                os.startfile(find_file)                found=True    if not found:        for i in os.walk('C:\Users\Jack\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch'):            search_path=i[0]            find_file=search_file('腾讯QQ.lnk',search_path)            if find_file:                os.startfile(find_file)                found=True    if not found:        for i in range(0,5):            for j in os.walk(disk[i]+':/'):                search_path=j[0]                find_file=search_file('QQProtect.exe',search_path)                if find_file:                    os.startfile(find_file)                    found=True    if not found:        for i in os.walk('C:/Program Files/QQ'):            search_path=i[0]            find_file=search_file('QQProtect.exe',search_path)            if find_file:                os.startfile(find_file)                found=True    if not found:        print"无法找到QQ"
