So how do you get data out of dictionaries? You retrieve your desired data using thekeyname. Image Source: Edlitera I'll show you how. Let's jump into a newJupyter notebookand write some code to make sense of all this. If you're not sure how to use Jupyter notebooks, here's a ...
The keys are separated from their respective values by a colon (:) between them, and each key-value pair is separated using commas (,). All items are enclosed in curly braces. While the values in dictionaries may repeat, the keys are always unique. The value can be of any data type,...

One last method involves using the Merge (|) and Update (|=) operators. They were introduced in Python 3.9. The merge (|) operator creates a new dictionary with the keys and values from both of the given dictionaries. You can then assign this newly created dictionary to a new variable....
