* Python has numerous libraries like `os`, `sys`, `json`, `yaml` etc that a DevOps Engineer uses in day-to-day tasks.
    

# Tasks:

* **Create a Dictionary in Python and write it to a JSON File.**
    
    The JSON module can be used to generate a dictionary in Python and write it to a JSON file:

    **json.load()** accepts a file object, parses the JSON data, fills a Python dictionary with the data, and returns it to you.

* **Read YAML file using python, file** `services.yaml` **and read the contents to convert yaml to json.**
    
    First, use the import statement to import the yaml module.
    
    Using the open method, read the file.
    
    Method of the safeloader reads the contents of the file and converts it to a dictionary Python object
