So I have been trying to build out a dynamic JSON library with python recently, and I'm having problems with looping through data. This problem is likely an easy fix but I am very new to programming and especially new to working with JSON.
Basically, I am trying to come out with a JSON output that looks similar to this:
{
"src_host": [
"list item 1",
[
"SSH",
"Telnet",
"STMP"
]
]
},
{
"src_host": [
"list item 2",
[
"SSH",
"Telnet",
"STMP"
]
]
}
I want to populate every "src_host" list with a single entry from another list. I basically want to have a src_host defined for every list item that is being provided. The code I am using is as shown below:
host_dict = {}
host_dict["src_host"] = []
host_services_list = ["SSH","Telnet","STMP"]
mylist = ["list item 1", "list item 2"]
counter = 0
for item in mylist:
json_data['zone'][0]['hosts'].append(host_dict)
host_dict['src_host'].append(mylist[counter])
counter = counter + 1
host_dict['src_host'].append(host_services_list)
The issue I am running into seems to be with the loop I have made to populate the Json data. For a reason I cannot figure out, when I execute this code, the Json output comes out like so:
{
"src_host": [
"list item 1",
"list item 2",
[
"SSH",
"Telnet",
"STMP"
]
]
},
{
"src_host": [
"list item 1",
"list item 2",
[
"SSH",
"Telnet",
"STMP"
]
]
}
As you can see, the list items "list item 1" and "list item 2" are appended to each src_host list, rather than "list item 1" being added to the first src_host and "list item 2" being added to the second.
I'm assuming my logic is flawed here or I'm missing something super simple, but I can't seem to get past this one problem at the moment and wanted to reach out for assistance.
Thank you for any and all help!
Note: The ['zone'][0]['hosts'] is because this portion of Json is a small piece in a larger Json file. I didn't think it was necessary to show every bit of the Json file but wanted to still explain just in case.
I don't think this data structure will do you any favors but here is a super simple list comprehension to get it done:
host_title = 'src_host'
host_services_list = ['SSH', 'Telnet', 'STMP']
mylist = ['list item 1', 'list item 2']
hosts = [{host_title: [item, host_services_list]}
for item in mylist]
import json
print(json.dumps(hosts, indent=2))
Output:
[
{
"src_host": [
"list item 1",
[
"SSH",
"Telnet",
"STMP"
]
]
},
{
"src_host": [
"list item 2",
[
"SSH",
"Telnet",
"STMP"
]
]
}
]
The key here is starting with mylist and building out the data from there, this may not work depending on the structure of the rest of your data though.
