# `tomllib` — Parse TOML files

Νέο στην έκδοση 3.11.

Source code: Lib/tomllib

This module provides an interface for parsing TOML (Tom’s Obvious Minimal Language, https://toml.io). This module does not support writing TOML.

The Tomli-W package is a TOML writer that can be used in conjunction with this module, providing a write API familiar to users of the standard library `marshal` and `pickle` modules.

The TOML Kit package is a style-preserving TOML library with both read and write capability. It is a recommended replacement for this module for editing already existing TOML files.

This module defines the following functions:

tomllib.load(fp, /, *, parse_float=float)

  Read a TOML file. The first argument should be a readable and binary file object. Return a `dict`. Convert TOML types to Python using this conversion table.

  parse_float will be called with the string of every TOML float to be decoded. By default, this is equivalent to `float(num_str)`. This can be used to use another datatype or parser for TOML floats (e.g. `decimal.Decimal`). The callable must not return a `dict` or a `list`, else a `ValueError` is raised.

  A `TOMLDecodeError` will be raised on an invalid TOML document.

tomllib.loads(s, /, *, parse_float=float)

  Load TOML from a `str` object. Return a `dict`. Convert TOML types to Python using this conversion table. The parse_float argument has the same meaning as in `load()`.

  A `TOMLDecodeError` will be raised on an invalid TOML document.

The following exceptions are available:

exception tomllib.TOMLDecodeError

  Subclass of `ValueError`.

## Examples

Parsing a TOML file:

    import tomllib

    with open("pyproject.toml", "rb") as f:
        data = tomllib.load(f)

Parsing a TOML string:

    import tomllib

    toml_str = """
    python-version = "3.11.0"
    python-implementation = "CPython"
    """

    data = tomllib.loads(toml_str)

## Conversion Table

TOML | Python
--- | ---
TOML document | dict
string | str
integer | int
float | float (configurable with parse_float)
boolean | bool
offset date-time | datetime.datetime (`tzinfo` attribute set to an instance of `datetime.timezone`)
local date-time | datetime.datetime (`tzinfo` attribute set to `None`)
local date | datetime.date
local time | datetime.time
array | list
table | dict
inline table | dict
array of tables | list of dicts
