TypeError: list indices must be integers, not dict
提问by user1124236
My json file look likes this and I'm trying to access the element syslogin a for loop.
我的 json 文件看起来像这样，我试图syslog在 for 循环中访问该元素。
{
"cleanup":{
"folderpath":"/home/FBML7HR/logs",
"logfilename":""
},
"preparation":{
"configuration":{
"src_configfile":"src.cfg",
"dest_configfile":"/var/home/FBML7HR/etc/vxn.cfg"
},
"executable_info1":[
{
"login_info":{
"hostname":"10.4.0.xxx",
"username":"***",
"password":"***"
}
},
{
"command":{
"folderpath":"/var/home/FBML7HR/SrcCode/vxnservers/fdchost/north/test/hostsim/",
"processname":"northhostsim",
"parameters":"-d"
}
}
],
"executable_info2":[
{
"login_info":{
"hostname":"10.4.0.xxx",
"username":"***",
"password":"***"
}
},
{
"command":{

}
}
],
"executable_info3":[

}
}
]
},
"execution":[
{
"test_case":{
"scriptname":"/var/home/FBML7HR/test/testcase1.sh",
"testreport":{
"syslog":"/var/log/messages",
"backupsyslog":"backuplogs1.txt",
"clientsimlog":"/var/home/FBML7HR/test/out.log",
"backupclientsimlog":"Clientlogs1.txt"
}
}
},
{
"test_case":{
"scriptname":"/var/home/FBML7HR/test/testcase2.sh",
"testreport":{
"syslog":"/var/log/messages",
"backupsyslog":"backuplogs2.txt",
"clientsimlog":"/var/home/FBML7HR/test/out.log",

}

"backupsyslog":"backuplogs.txt",
"reportfilename":"/var/home/FBML7HR/test/out.log",
"backuplogfile":"Clientlogs.txt"
}
}
}
I do it like this:
我这样做：
for i in data['execution']:
cmd = data['execution'][i]['test_case']['scriptname']
But I get the error saying "TypeError: list indices must be integers, not dict". I'm new to python (and json as well). Could anybody suggest where I'm going wrong ?
但是我收到错误消息“类型错误：列表索引必须是整数，而不是字典”。我是 python （以及 json ）的新手。有人可以建议我哪里出错了吗？

You are looping over the valuesin the list referenced by data['execution'], notindices.
您正在遍历由 引用的列表中的值data['execution']，而不是索引。
Just use those values (dictionaries) directly:
只需直接使用这些值（字典）：
for i in data['execution']:
cmd = i['test_case']['scriptname']
You probably want to give that a more meaningful loop name:
你可能想给它一个更有意义的循环名称：
for entry in data['execution']:
cmd = entry['test_case']['scriptname']
