One of the most versatile aspects of Python dictionaries is the ability to unpack them. Ever wondered how to use dictionary values as function arguments?
Simply employ the ** operator**:
def greet(name, age):
return f"Hello {name}, you're {age} years old!"
data = {'name': 'Jane', 'age': 28}
print(greet(**data)) # This will print: Hello Jane, you're 28 years old!
Let's dive deeper into a practical use case:
Imagine making multiple API calls, where every call has a different template with a unique URL, endpoint, and parameters.
You'd need a systematic way to manage this. Here's when dictionary unpacking comes to the rescue.
We're separating the templates and configuration and then leveraging dictionary unpacking for a flexible yet clean approach.
