Converting “true” (JSON) to Python equivalent “True”

Even though Python’s object declaration syntax is very similar to Json syntax, they’re distinct and incompatible. As well as the True/true issue, there are other problems (eg Json and Python handle dates very differently, and python allows single quotes and comments while Json does not).

Instead of trying to treat them as the same thing, the solution is to convert from one to the other as needed.

Python’s native json library can be used to parse (read) the Json in a string and convert it into a python object, and you already have it installed…

# Import the library
import json
# Define a string of json data
data_from_api = '{"response_code": 200, ...}'
data = json.loads(data_from_api)
# data is now a python dictionary (or list as appropriate) representing your Json

You can convert python objects to json too…

data_as_json = json.dumps(data)

Example:

# Import the json library
import json

# Get the Json data from the question into a variable...
data_from_api = """{
"response_code": 200,
  "train_number": "12229",
  "position": "at Source",
  "route": [
    {
      "no": 1, "has_arrived": false, "has_departed": false,
      "scharr": "Source",
      "scharr_date": "15 Nov 2015", "actarr_date": "15 Nov 2015",
      "station": "LKO", "actdep": "22:15", "schdep": "22:15",
      "actarr": "00:00", "distance": "0", "day": 0
    },
    {
      "actdep": "23:40", "scharr": "23:38", "schdep": "23:40",
      "actarr": "23:38", "no": 2, "has_departed": false,
      "scharr_date": "15 Nov 2015", "has_arrived": false,
      "station": "HRI", "distance": "101",
      "actarr_date": "15 Nov 2015", "day": 0
    }
  ]
}"""

# Convert that data into a python object...
data = json.loads(data_from_api)
print(data)

And a second example showing how the True/true conversion happens. Note also the changes to quotation and how the comment is stripped…

info = {'foo': True,  # Some insightful comment here
        'bar': 'Some string'}

# Print a condensed representation of the object
print(json.dumps(info))

> {"bar": "Some string", "foo": true}

# Or print a formatted version which is more human readable but uses more bytes
print(json.dumps(info, indent=2))

> {
>   "bar": "Some string",
>   "foo": true
> }
