各位：

我有段python脚本，运行时报错，信息如下：

2016-07-12 10:59:14,777 INFO  agent: worker uapgv4190.us.oracle.com-0 started
2016-07-12 10:59:16,186 ERROR uapgv4190.us.oracle.com-0: aborting process - Jython exception, <type 'exceptions.SyntaxError'>: ("no viable alternative at input '/'", ('./test_ldap.py', 70, 15, "      f = open(/tmp/ldaptest.log, 'a+')\n")) [initialising test script]

我的脚本就是不断运行ldap search命令，脚本如下：

以前脚本输出显示先屏幕上运行正常，添加了一段代码把查询信息输出在文件里就报错了，添加的代码如下：

1. f = open(/tmp/ldaptest.log, 'a+')
   
2.       f.write(result)
   
3.       f.close()

复制代码

不知道哪里写错了？ 请指点下 谢谢

1.       f = open(/tmp/ldaptest.log, 'a+')  #文件路径也是字符串 所以要用单引号或者双引号框起    f = open("/tmp/ldaptest.log", 'a+')
   
2.       f.write(result)
   
3.       f.close()

非常谢谢！ 我试试

bskay

      f = open(/tmp/ldaptest.log, 'a+')
      f.write(result)
      f.close()

这个是C思维,python下一般不需要close的,直接写

file("/tmp/ldaptest.log","a+").write(result)

多谢指点。回复 4# bskay
