When a function needs to accept flexible named options, a keyword parameter dictionary collects them into one mapping. **kwargs is the conventional name, not a required one. The function can inspect expected keys, while extra pairs may be ignored or passed to another function. Use this flexibility intentionally: explicit, named parameters are often clearer when the accepted data is known. section 3.2.2
Inspecting named values
A function such as full_name(**kwargs) can look up fname, mname, and lname in kwargs. This supports keyword-based calls without fixing the parameter list, but users need documentation to know which keys matter. Unrecognized key-value pairs have no effect unless the function forwards the mapping to another function. section 3.2.2
def full_name(**kwargs):
[CA]return f"{kwargs.get('fname', '')} {kwargs.get('mname', '')}
{kwargs('lname', '')}"
Inspect the compact full_name definition to see **kwargs used as a dictionary-like collection of named values. section 3.2.2
