File types

pyntree currently supports a plethora of file types:

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 pyndb.

Filetype parameter: json

Supported file extensions:

  • .json

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.

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

Filetype parameter: txt

Supported file extensions:

  • .txt
