Nulls, instead of Nones, in JSON Data with Python
json, python, python-2.7
Solution
Much simpler!
Just assign `None` to `null` before assigning that list to a variable:
null = None
var = [{"title": null, "metric1": 361429, "metric2": 36,},{"title": null, "metric1": 253798, "metric2": 48}]
Then you won't need to do the rather unnecessary conversion to a string (and back to a Python object with `json.loads`) only to replace `null` by `None`.
But that is only really necessary if you're copy-pasting that code from some source. Otherwise, the canonical answer is to use `json.loads` (or `json.load`).
Problem
I'm working with the following data: ``` [{"title": null, "metric1": 361429, "metric2": 36,},{"title": null, "metric1": 253798, "metric2": 48}] ``` When I attempt to assign this data to a variable in Python (with the aim of parsing it out), I receive the following error message: ``` Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'null' is not defined ``` From my research, it appears that the `None` is Python's `null`. What I'm wondering is, is it possible to change the `null`'s in my data to `None`'s using Python? I've tried creating a string out of the data, assigning it to `data`, and replacing the `null`'s that way: ``` data = data.replace('null','None') ``` but that results in a string of the data itself: ``` data = '[{"title": None, "metric1": 361429, "metric2": 36,},{"title": None, "metric1": 253798, "metric2": 48}]' ``` and I can't figure out how to turn it from a string back into JSON. EDIT: I am copying and pasting this data into the Python interpreter from a separate source.
