Intro

Tomli-W is a Python library for writing TOML. It is a write-only counterpart to Tomli, which is a read-only TOML parser. Tomli-W is fully compatible with TOML v1.0.0.

Installation

pip install tomli-w

Usage

Write to string

import tomli_w

doc = {"table": {"nested": {}, "val3": 3}, "val2": 2, "val1": 1}
expected_toml = """\
val2 = 2
val1 = 1

[table]
val3 = 3

[table.nested]
"""
assert tomli_w.dumps(doc) == expected_toml

Write to file

import tomli_w

doc = {"one": 1, "two": 2, "pi": 3}
with open("path_to_file/conf.toml", "wb") as f:
    tomli_w.dump(doc, f)

FAQ

Does Tomli-W sort the document?

No, but it respects sort order of the input data, so one could sort the content of the dict (recursively) before calling tomli_w.dumps.

Does Tomli-W support writing documents with comments, custom whitespace, or other stylistic choices?

No.
