"tomllib" --- Parse TOML files
******************************

New in version 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.

See also:

  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.

See also:

  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)
