将数组转换为连接字符串的逗号分隔的脚本

Question

我试图获取以逗号分隔的LDAP数据库中存储的所有电子邮件地址的列表。

通过简化这个script我：

#!/usr/bin/env python 
# encoding: utf-8 

# Author: Zhang Huangbin <zhb _at_ iredmail.org> 
# Purpose: Add enabledService=lib-storage for all mail users. 
#   Required by IMAP folder sharing in Dovecot-2.0. 
# Date:  2012-05-18 

import sys 
import ldap 

# Note: 
# * bind_dn must have write privilege on LDAP server. 
uri = 'ldap://127.0.0.1:389' 
basedn = 'o=domains,dc=example,dc=com' 
bind_dn = 'cn=Manager,dc=example,dc=com' 
bind_pw = 'password' 

# Initialize LDAP connection. 
print >> sys.stderr, "* Connecting to LDAP server: %s" % uri 
conn = ldap.initialize(uri=uri, trace_level=0,) 
conn.bind_s(bind_dn, bind_pw) 

# Get all mail users. 
print >> sys.stderr, "* Get all mail accounts..." 
allUsers = conn.search_s(
     basedn, 
     ldap.SCOPE_SUBTREE, 
     "(objectClass=mailUser)", 
     ['mail', 'enabledService'], 
     ) 

total = len(allUsers) 
print >> sys.stderr, "* Total %d user(s)." % (total) 

# Counter. 
count = 1 

for user in allUsers: 
    (dn, entry) = user 
    mail = entry['mail'][0] 

    print >> "%s, " % (mail) 

    count += 1 

# Unbind connection. 
conn.unbind() 

当我运行此我得到错误：

• Connecting to LDAP server: ldap://127.0.0.1:389
• Get all mail accounts...
• Total 64 user(s). Traceback (most recent call last): File "list_mail_users.py", line 43, in print >> "%s, " % (mail) AttributeError: 'str' object has no attribute 'write'

我问这个问题上的支持论坛和他们建议我使用：ldapsearch的呢？

Answer 1

这是你的问题

for user in allUsers: 
    (dn, entry) = user 
    mail = entry['mail'][0] 

    print >> "%s, " % (mail) 

    count += 1 

您正在试图打印到“％s的”，这是一个字符串，打印只能接受一个写属性的对象。我不完全确定你想要做什么，但我期望像print >> sys.stdout, "%s, " %(mail)或print >> File "%s, "%mail
