How to create a python variable from a json format - json

Question

I want to create a global variable from json data. I'm sending the json data with websockets from a server to a client and I want that when the client receives json data, it creates a global variables for further use.
My json data is:
set_variable_data = [{
'component' : {
'name' : input("Component name: "),
'evse' : {
'id' : int(input("Number of Evses: ")),
'connector_id' : int(input("Number of connectors: "))
}
},
'variable' : {
'name' : input("Variable name: ")
}
}]
And I've tried to implement this code into the client program:
global set_variable_data[0]['variable']['name'] = set_variable_data[0]['component']['evse']['connector_id']
There's no problem with the send/receive procedures, all the messages are sent and received between the client and the server. I just want to know if we can create a global variable from this.
Thanks in advance

You can use the global keyword to modify a global variable from inside the function thar receives the data:
variable_data = {}
def receive_data(interface):
global variable_data
variable_data = interface.recv_json()
The global keyword allows to reference the variable variable_data when is assigned a value to it, in other case you will be making the assignation to a variable only inside the context of the function.
