Python如何循环遍历包含变量的字符串列表？

我正在处理一些数据，并根据

incident\u source

创建一个查询列表。当我没有添加需要+符号的变量时，它工作得很好。当我添加时，我得到：

TypeError:只能将str（而不是“list”）连接到str

。有人知道解决这个问题的方法或更好的解决方案吗

source = 1
offense_id = [122,153,142]
incident_source = ['source_1', 'source_2']
num_searches_by_id = []
queries_needed_ran = []

for i,j in zip(incident_source, offense_id):
    if i == 'source_1':
        data = ['''SELECT QIDNAME(qid) AS 'Event Name',"Request Method" FROM events WHERE URL=REPLACEFIRST('hxxp',''' + "'" + source + "'" + ''','http') START ''' + str(start_time) + '''-43200000''',
                '''select QIDNAME(qid) as 'Event Name', "Recepient" from events where ( "URL"=''' + "'" + str(source) + "'" + '''AND logSourceId='1' ) START ''' + str(start_time) + '''-43200000''']
        num_searches_by_id.append(len(data))
        for x in data:
            queries_needed_ran.append(x)
            
    elif i == 'source_2':
        data = ['''select QIDNAME(qid) as 'Event Name', "Recepient" from events where ( "URL"=''' + "'" + str(source) + "'" + '''AND logSourceId='1' ) START ''' + str(start_time) + '''-43200000''']
        num_searches_by_id.append(len(data))
        for x in data:
            queries_needed_ran.append(x)
    else:
        num_searches_by_id.append(0)

因此，我不确定您的一些变量以及它们来自何处，但我消除了

类型错误：只能通过在
if
语句中为您查找的索引放置括号并更改变量，将str（而不是“list”）连接到str

。也不确定开始时间从哪里来

offense_id = [122,153,142]
incident_source = ['source_1', 'source_2']
num_searches_by_id = []
queries_needed_ran = []

for i,j in zip(incident_source, offense_id):
    if i == 'source_1':
        data = ['''SELECT QIDNAME(qid) AS 'Event Name',"Request Method" FROM events WHERE URL=REPLACEFIRST('hxxp',''' + "'" + incident_source[0] + "'" + ''','http') START ''' + str(start_time) + '''-43200000''',
                '''select QIDNAME(qid) as 'Event Name', "Recepient" from events where ( "URL"=''' + "'" + str(incident_source[0]) + "'" + '''AND logSourceId='1' ) START ''' + str(start_time) + '''-43200000''']
    num_searches_by_id.append(len(data))
    for x in data:
        queries_needed_ran.append(x)
        
    elif i == 'source_2':
        data = ['''select QIDNAME(qid) as 'Event Name', "Recepient" from events where ( "URL"=''' + "'" + str(incident_source[1]) + "'" + '''AND logSourceId='1' ) START ''' + str(start_time) + '''-43200000''']
        num_searches_by_id.append(len(data))
        for x in data:
            queries_needed_ran.append(x)
    else:
        num_searches_by_id.append(0)

什么是源代码？你的预期产出是什么？你的问题不清楚。实际导致错误的输入是什么？您遇到的错误的完整回溯是什么？您发布的错误位意味着您的输入在错误发生时是一个列表，而不是列表中的字符串。source=1@PacketLoss@G.Anderson我的问题是，我可以循环遍历一个不包含“++”的列表，但是当我添加“++”时，我得到一个类型错误：只能将str（而不是“list”）连接到strAh。。您似乎希望

source

指示列表中指定的

source

。你可以通过

i

来访问它，这是你在循环开始时定义的。我现在完全明白了。因此，在它能够很好地处理没有列表变量的查询之前。现在，它从一个列表中提取数据，我试图以字符串的形式传递该列表。哇！应该将列表的索引用作字符串：）。非常感谢。别担心。我将实际值放在这里供您查看，但是@PacketLoss是正确的，您可以根据您的条件传递

I

。此外，如果您使用的是Qradar的API，那么Qradar应该能够处理SQL构造

offense_id = [122,153,142]
incident_source = ['source_1', 'source_2']
num_searches_by_id = []
queries_needed_ran = []

for i,j in zip(incident_source, offense_id):
    if i == 'source_1':
        data = ['''SELECT QIDNAME(qid) AS 'Event Name',"Request Method" FROM events WHERE URL=REPLACEFIRST('hxxp',''' + "'" + incident_source[0] + "'" + ''','http') START ''' + str(start_time) + '''-43200000''',
                '''select QIDNAME(qid) as 'Event Name', "Recepient" from events where ( "URL"=''' + "'" + str(incident_source[0]) + "'" + '''AND logSourceId='1' ) START ''' + str(start_time) + '''-43200000''']
    num_searches_by_id.append(len(data))
    for x in data:
        queries_needed_ran.append(x)
        
    elif i == 'source_2':
        data = ['''select QIDNAME(qid) as 'Event Name', "Recepient" from events where ( "URL"=''' + "'" + str(incident_source[1]) + "'" + '''AND logSourceId='1' ) START ''' + str(start_time) + '''-43200000''']
        num_searches_by_id.append(len(data))
        for x in data:
            queries_needed_ran.append(x)
    else:
        num_searches_by_id.append(0)
