TOML File Format

Key/value pairs, sections/tables, and comments make up the majority of TOML files, which also need to be valid UTF-8-encoded Unicode documents. The following data types are supported by TOML: String, Integer, Float, Boolean, Datetime, Array, and Table (hash table/dictionary). A case-sensitive language is TOML. Here’s a brief overview of the syntax for TOML files:

• Comments start with the # character and continue until the end of the line.
• Key-value pairs are represented as key = value and are separated by a new line.
• Keys can be nested using square brackets to create a hierarchy of sections, like [section1.subsection1].
• Values can be strings (in quotes), integers, floats, booleans, dates/times (in ISO 8601 format), arrays (in square brackets), or tables (in curly braces).
• Arrays can contain any type of value, including other arrays or tables.
• Tables represent a group of key-value pairs and can be used to group related configuration settings together. Tables can have their own sections and can be nested within other tables.
• Whitespace (spaces, tabs, and newlines) is significant in TOML files and should be used consistently to ensure that the file is parsed correctly.

UseCase of TOML Module

• Configuration files: TOML is often used as a configuration file format for Python applications. The toml module can be used to parse these configuration files and load the configuration data into the application.
• Data serialization: TOML can be used to serialize and deserialize Python data structures. The toml module provides methods for converting Python dictionaries to and from TOML data.
• Interoperability: TOML is a cross-language format, which means that TOML data can be easily shared between different programming languages. The toml module can be used to convert Python data structures to TOML, which can then be easily shared with other languages.
• Testing: TOML can be used as a test fixture format, allowing developers to write test cases in TOML format and use the toml module to load and run the test cases in Python.

Directory Structure : 

TOML file stand for (Tom’s Obvious, Minimum Language). The configuration files can be stored in TOML files, which have the .toml extension. Due to its straightforward semantics, which strives to be “minimal,” it is supposed to be simple to read and write. It is also made to clearly map to a dictionary. The TOML’s syntax primarily consists of key = value pairs. This makes TOML intended to be simple for people to read and create while simultaneously being clear and simple for computers to parse. Also, TOML is utilized as an alternative to other configuration files formats like JSON and YAML.

Required Module:

By executing the following command in your terminal or command prompt, you can use PIP  to install the package.

pip install toml
