print python json dump onto multiple lines

[lhailey]

I am trying to print the payload variable onto multiple lines. It currently prints on one line.
I am using the indent statement but it still prints on one line.
Can you help?

Step 1:

1 2 3 4 5 6 7

payload = json.dumps({"ip-detunnel": "No",                       "name": "DP800 Slot 1",                       "vlan-tag-insertion": "No",                       "vlan-tag-remove-forward": "Remove",                       "mac-replace-header": "No",                       "mpls-label-stack": "Pass Through"                       })

Step 2:

1	print '\n' + (json.dumps(payload, indent=4))

Step 3:
Results:

Output:
"{\"vlan-tag-insertion\": \"No\", \"name\": \"DP800 Slot 1\", \"mpls-label-stack\": \"Pass Through\", \"vlan-tag-remove-forward\": \"Remove\", \"ip-detunnel\": \"No\", \"mac-replace-header\": \"No\"}"

You have made a json string from a dict and then passing that string to json.dumps.
either just pass the dict directly

1 2 3 4 5 6 7 8 9

import json   print(json.dumps({"ip-detunnel": "No",                    "name": "DP800 Slot 1",                    "vlan-tag-insertion": "No",                    "vlan-tag-remove-forward": "Remove",                    "mac-replace-header": "No",                    "mpls-label-stack": "Pass Through"                    }, indent=4))

Output:
{
    "ip-detunnel": "No",
    "name": "DP800 Slot 1",
    "vlan-tag-insertion": "No",
    "vlan-tag-remove-forward": "Remove",
    "mac-replace-header": "No",
    "mpls-label-stack": "Pass Through"
}

or turn the string back to a dict

1 2 3 4 5 6 7 8 9 10 11 12

import json   payload = json.dumps({"ip-detunnel": "No",                       "name": "DP800 Slot 1",                       "vlan-tag-insertion": "No",                       "vlan-tag-remove-forward": "Remove",                       "mac-replace-header": "No",                       "mpls-label-stack": "Pass Through"                       })     print(json.dumps(json.loads(payload), indent=4))

Output:
{
    "ip-detunnel": "No",
    "name": "DP800 Slot 1",
    "vlan-tag-insertion": "No",
    "vlan-tag-remove-forward": "Remove",
    "mac-replace-header": "No",
    "mpls-label-stack": "Pass Through"
}

Note: The json.dumps() method encodes any Python object into JSON formatted String.
Here when you passed dictionary to json.dumps(), it converted it into a JSON formatted string.

When you want to prettyPrint JSON data, we can use indent, sort_keys parameters of dumps() method

Example:

1 2 3 4 5 6 7 8 9

import json    print(json.dumps({"ip-detunnel": "No",                    "name": "DP800 Slot 1",                    "vlan-tag-insertion": "No",                    "vlan-tag-remove-forward": "Remove",                    "mac-replace-header": "No",                    "mpls-label-stack": "Pass Through"                    }, indent=2, sort_keys=True))

Output:

1 2 3 4 5 6 7 8

{   "ip-detunnel": "No",   "mac-replace-header": "No",   "mpls-label-stack": "Pass Through",   "name": "DP800 Slot 1",   "vlan-tag-insertion": "No",   "vlan-tag-remove-forward": "Remove" }
