yaml (yaml ain't markup language) is a human-readable data serialization format. it is commonly used for configuration files and data exchange between languages with different data structures. python 3 has a built-in module called yaml that makes it easy to work with yaml files.
in this tutorial, we'll cover the basics of working with yaml in python 3, including reading and writing yaml files, as well as parsing and emitting yaml data.
before we begin, ensure that the pyyaml library is installed. if not, you can install it using the following command:
let's start by reading data from a yaml file. consider the following yaml file named example.yaml:
now, let's create a python script to read and parse this yaml file:
in this example, we use yaml.safe_load() to load the yaml data from the file safely. the loaded data becomes a python dictionary, and we can access its elements as usual.
now, let's explore how to create a yaml file from python data. suppose we have a dictionary representing a person's information:
we can write this data to a yaml file using the following code:
in this example, yaml.dump() is used to serialize the python dictionary into yaml format and write it to the specified file.
