Question

python open问题

比如我想要open一条有变量的路径，
open("/home/pythondj/linsite/html/",offset,".html","rb")
offset是变量
像上面那样不行吗？应该怎么写？

Answer 1

open("/home/pythondj/linsite/html/%s.html" % offset,"rb")

Answer 2

import os.path

offset = '233' # or any you want
homepath = r"/home/pythondj/linsite/html"
open(os.path.join(homepath, offset+".html"),"rb")
