在python中使用wget(错误代码帮帮我)

继承我的代码.

import os, sys
if len(sys.argv) != 2:
     sys.exit(1)

h = os.popen("wget -r %s") % sys.argv[1]
fil = open("links.txt","w")
dir = os.listdir("%s") % sys.argv[1]

for file in dir:
     print file.replace("@","?")
     fil.write("%s/"+file.replace("@","?")) % sys.argv[1]
     fil.write("\n")
h.close()

运行它,就像这个python project.py http://google.com

给我错误代码.

1.py:5 RuntimeWarning: tp_compare didnt return -1 or -2 for exception
h = os.popen("wget -r %s") % sys.argv[1]
