3/1/2024 0 Comments Python json string to list![]() If you’re parsing JSON files on a regular basis, and you’re hitting performance or memory issues, or you just want built-in schemas, consider giving it a try. This example is similar to the one above note the output is the same in any case. As recent versions of the docs explain: 'Warning It is possible to crash the Python interpreter with a sufficiently large/complex string due to stack depth limitations in Python’s AST compiler.' It may, in fact, be possible to run arbitrary code via a careful stack-smashing attack, although as far as I know nobody's build a public proof of. The main benefit here is a bunch of added helper class methods, like listtojson which will serialize a list of dataclass instances to JSON, which seems like it could be useful in this case. Msgspec has additional features, like encoding, MessagePack support (a faster alternative format to JSON), and more. To make things a bit simpler, you can opt to subclass from the JSONWizard Mixin class.
