Python-循环遍历文件夹

for root,dirs,files in os.walk(payloadPath):
    for tempFile in files:
    path = os.path.join(root,tempFile)
    # print "文件路径 =" +path
    with open(path,"rb") as file:
            for line in file:
                  if (line.find("xxxx")>0):
                      print "******存在******"
                      #写日志
                       filePath = path+"\n"
                       fileList.append(filePath)
                       break
