Question

JSON is very similar to Python syntax. Can all JSON objects directly convert to Python without error?

Example

The following is a valid JSON object:

// Valid JSON
{"foo":"bar"}

This object will directly translate to a Python dictionary with key “foo” and value “bar”:

# Python
json_dict = eval('{"foo":"bar"}')

Answer 1

No. In particular, true, false, and null are not Python, although they do have direct equivalents in Python (True, False, and None respectively).

// Valid JSON
{"sky_is_blue":true}

But when used in Python…

# Python
>>> json_dict = eval('{"sky_is_blue":true}')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1, in <module>
NameError: name 'true' is not defined
