如何修复python中的文件“<string>”错误

Question

我试着做一个简单的脚本，并在for循环中抛出下面的错误

WASX7017E: Exception received while running file "/abc/websphere/wasad/createusers.py"; 
exception information: com.ibm.bsf.BSFException: exception from Jython:
Traceback (innermost last):
File "<string>", line 22, in ?
AttributeError: __getitem__

filename=sys.argv[0]
file_read= open( filename)   ---- this is line 22
for row in file_read:

请告诉我原因。

在这里你可以找到我的密码

  import sys

  filename="/usr/websphere/onefolder/Userlist.txt"
  fileread = open(filename, 'r')
  for row in fileread:
     column=row.strip().split(';')
     user_name=column[0]
     pass_word=column[1]
     AdminTask.createUser(['-uid',user_name, '-password', pass_word, '-confirmPassword',   pass_word])
     AdminTask.mapUsersToAdminRole(['-roleName','Administrator','-userids',user_name])
     AdminTask.addMemberToGroup('[-memberUniqueName user_name,o=defaultWIMFileBasedRealm -groupUniqueName cn=webarch,o=defaultWIMFileBasedRealm]')

  fileread.close()

  AdminConfig.save()

  print 'Saving Configuration is completed'
