File types

pyntree currently supports a plethora of file types, all of which can be encrypted:

Pickle (default)

Pickled data is python data saved directly to a file as bytes. This way, you can save objects (ex: datetime) without losing any data or causing any problems while trying to reload the file.

Filetype parameter: pyn

Supported file extensions:

• .pyn
• .pyndb
• .pkl

Compressed (and pickled)

Compressed data can be saved in a variety of formats, thanks to the compress_pickle module. For a full list of supported file extensions and types, see here.

JSON

JSON data can be saved and loaded with pyntree.

Filetype parameter: json

Supported file extensions:

• .json

YAML

YAML data can also be saved and loaded with pyntree.

Filetype parameter: yaml

Supported file extensions:

• .yaml
• .yml

Plain text

Saving python objects to a plaintext file will likely cause loading issues since pyntree will use eval() to load the data. This means that if it tries to create an object from a class it hasn't imported, the loading will fail. Additionally, the reliance on the eval() function means that you should only load trusted plaintext files, as loading untrusted ones could present a security risk.

You can also save the data as a string representation of the dictionary.

Filetype parameter: txt

Supported file extensions:

• .txt
