How is YAML used in Python?

YAML (YAML Ain’t Markup Language) is a human-readable data-serialization language. It is commonly used for configuration files, but it is also used in data storage (e.g. debugging output) or transmission (e.g. document headers). There are two modules in Python for YAML: PyYAML and ruamel.

How do I read a YAML file in Python?

We can read the YAML file using the PyYAML module’s yaml. load() function. This function parse and converts a YAML object to a Python dictionary ( dict object). This process is known as Deserializing YAML into a Python.

Why is YAML so popular?

What is the YAML language?

YAML is the abbreviated form of “YAML Ain’t markup language” is a data serialization language which is designed to be human -friendly and works well with other programming languages for everyday tasks.
