Python 强制使用Unicode：需要字符串或缓冲区，找到列表

我有一个django rest框架视图，其中包含以下代码-

trgmst_info = request.DATA['trgmst_info'][0]
request_accts = ['request-dev', 'request-qa', 'request-uat', 'request-prod']
request.DATA['trgmst_info'] = [rd.replace(request_accts, settings.REQUEST_ACCT) for rd in request.DATA['trgmst_info']]

request.DATA['trgmst_info'][0]的值如下所示-

"<eventmon><conn>24</conn><action>3</action><folder/><mailbox>Inbox</mailbox><condition><condcount>1</condcount><criteria1>Sender</criteria1><ctext1>test_MESSage</ctext1><csensitive1>Y</csensitive1></condition><msgbody>Y</msgbody><evtmtrg>Inbox (request-dev@mailserver.blah.com)</evtmtrg></eventmon>"

编辑-如果我在第一行之后偷偷输入以下代码-

print trgmst_info

它返回字符串。replace（）将字符串用作参数而不是列表。 申请账户 这是一份清单

我不是django专家，但也许这会奏效：

trgmst_info = request.DATA['trgmst_info'][0]
request_accts = ['request-dev', 'request-qa', 'request-uat', 'request-prod']
for rep in request_accts:
    request.DATA['trgmst_info'] = [rd.replace(rep, settings.REQUEST_ACCT) for rd in request.DATA['trgmst_info']]

啊，我找错位置了。那么，如何让它检查列表中提供的每个值的字符串呢？

trgmst_info = request.DATA['trgmst_info']

<eventmon><conn>24</conn><action>3</action><folder/><mailbox>Inbox</mailbox><condition><condcount>1</condcount><criteria1>Sender</criteria1><ctext1>test_MESSage</ctext1><csensitive1>Y</csensitive1></condition><msgbody>Y</msgbody><evtmtrg>Inbox (request-dev@mailserver.blah.com)</evtmtrg></eventmon>

trgmst_info = request.DATA['trgmst_info'][0]
request_accts = ['request-dev', 'request-qa', 'request-uat', 'request-prod']
for rep in request_accts:
    request.DATA['trgmst_info'] = [rd.replace(rep, settings.REQUEST_ACCT) for rd in request.DATA['trgmst_info']]
