Add variable value to string - pythonlearner1 - May-24-2020

I am creating variable

dashboard_id="66862fa0-dafa-4d28572533a"

I want to create a another variable and insert this value to it

Output:{ "objects":[
   {
 "type":"dashboard",
 "id":"66862fa0-dafa-4d28572533a"
 } ] ,
 "includeReferencesDeep": true
}

this is how i am creating this but do not know how to replace this id

data = '\n{ "objects":[\n   {\n "type":"dashboard",\n "id":"66862fa0-dafa-4d28572533a"\n } ] ,\n "includeReferencesDeep": true\n}'

Use and F-String.

id = "66862fa0-dafa-4d28572533a"

string = f"some stuff{id}some more stuff"

I did do this and it worked. but now thinking if I can do this in one line

      data1 = '\n{ "objects":[\n   {\n "type":"dashboard",\n "id":'
      data2 = '\n } ] ,\n "includeReferencesDeep": true\n}'
      data = data1 + '"' + dashboard_id + '"' + data2

Michael, that does not work beceasue I have { and ' and \n all in that string. it gives me error

You are creating JSON. Of course one way is to use string manipulation/str methods to do it.
Better way is to use json module

import json

data = {"objects":[],
        "includeReferencesDeep": True}

dashboard_id = "66862fa0-dafa-4d28572533a"
data['objects'].append({'type':'dashboard', 'id':dashboard_id})


json_string = json.dumps(data, indent=4)
print(json_string)

Output:{
    "objects": [
        {
            "type": "dashboard",
            "id": "66862fa0-dafa-4d28572533a"
        }
    ],
    "includeReferencesDeep": true
}

There could be more objects, other objects types, etc. You need to learn to manipulate json.

Thank you Buran, That is what I needed. yes I never thought that I am setting up json. still stuck in old way of doing (bash scripting)

If you do stuff in shell scripts, do you know about jq? It's a really handy command line tool for doing stuff with JSON.
