错误输出： 文件 "./wlc-auto-rf.py"，第 34 行，在 child.sendline ('show ap auto-rf' ['radio']['apname']( 类型错误：字符串索引必须是整数，而不是 str

任何帮助，不胜感激。

here is the script:
!/usr/bin/python 
#
#       requires python pexpect module
#
import pexpect
import sys
firstarg=sys.argv[0]
address=sys.argv[1]
username=sys.argv[2]
password=sys.argv[3]
radio=sys.argv[4]
apname=sys.argv[5]
output=sys.argv[6]
child = pexpect.spawn ('ssh' , [address])
child.expect ('User:')
child.sendline (username)
child.expect ('Password:')
child.sendline (password)
child.expect ("Controller")
child.sendline ('config paging disable')
#
child.expect ("Controller")
child.sendline ('show ap auto-rf' ['radio']['apname'])
child.logfile = open(output , "w")
child.expect ("Controller")
child.sendline ('logout')
child.expect('(y/N)')
child.sendline ('N')
child.expect(pexpect.EOF)

我能够使用字符串连接将变量一起添加到一个字符串中来修复它 child.sendline ('show ap auto-rf '+radio+' '+apname(
