Passing value to nested JSON in Python?

Question

I try to pass a variable to nested JSON in Python script.

Script as below,

import requests, request

group = request.form['grp']
zon = request.form['zone']

load = { "extra_vars": {
                 "g_name": "' +str(group)+ '",
                 "z_name": "' +str(zon)+ '"
                 }
       }

----

However when i post the value to the API, it seem i post word '+str(group)+' and '+str(zon)+' instead the actual value that assign under declared variable.

Since i'm very new in Python programming, does passing value to nested JSON is allow in Python?

Try the following:

group = request.form['grp']
zon = request.form['zone']

load = { "extra_vars": {
                 "g_name": f"{group}",
                 "z_name": f"{zon}"
                 }
       }

If you don't need to enclose group around a quote, then it's actually even easier to just use: "g_name": str(group) or "g_name": quote if quote is a string. No need for an f-string

You can pass variables into a string using f-strings and brackets around your variable (note {group}):

>>> group = "my_group"
>>> {"g_name": f"'{group}'"}
{'g_name': "'my_group'"}

Or doing simple string concatenation also, which is what you almost done in your code (but just did not properly close the ' character using "'":

>>> "'" + str(group) + "'"
"'my_group'"

All in all here's your code adapted:

load = { "extra_vars": {
                 "g_name": f"'{group}'",
                 "z_name": f"'{zon}'"
                 }
       }
