How to access data from nested dicts json? - json

Question

I want to get some data from a json file. I can access everything with the code below.
import json
with open('C:\\Users\\me\\Documents\\stdin.json', 'r', encoding='utf8', errors='ignore') as json_file:
data = json.load(json_file)
print("Type: ", type(data))
print("VM: ", data["Datacenter"])
The .json file looks like this:
{
"Datacenter":[
{
"Folder":[
{
"Folder":[
{
"VirtualMachine":[
{
"moid":"vm-239566",
"name":"DEV CentOS 6",
},
{
"moid":"vm-239464",
"name":"DEV Sles 12",
},
],
"moid":"group-v239127",
"name":"DEV-VMs"
},
],
"moid":"group-v78",
"name":"Test and Dev"
},
{
"VirtualMachine":[
{
"moid":"vm-66130",
"name":"Hyv16-clone",
}
],
"moid":"group-v77",
"name":"Templates"
}
],
"moid":"datacenter-21",
"name":"Datencenter"
}
],
"vSphereHost":"srv01",
"vSphereProductLine":"vpx",
"vSphereServer":"VMware vCenter Server",
"vSphereVersion":"xxx",
"version":"1.0",
"viewType":"VMs and Templates"
}
Note that the original json file was much bigger as I deleted lines for readabilty. Also note that I run everything from Command Line, as my IDE always gives me the error UnicodeEncodeError: 'charmap' codec can't encode characters in position 22910-22912: character maps to <undefined>
I tried to use data["VirtualMachine"] instead of data["Datacenter"] but then I get an error... TypeError: 'VirtualMachine' is an invalid keyword argument for this function.
So how can I get/print the moid and name of a VM? I am really new to coding and don´t know how to deal with nested dictionarys

However your question does not seems clear but from whatever you have mentioned this can be help you deriving the value in nested json if you have already have dataframe created. You can go ahead and add get() till you reach what you require. Below is the sample that you can use
import json
data = data.apply(lambda x: json.loads(json.loads(x).get("Folder","{}")).get("moid") if x else None)
