The second part of the document has a lot of detail on each of the summary items. For the purpose of this exercise, I am only going to scrape the summary section but the same basic principle can be applied to the detailed line items. One final note, I realize that this data set is ...
Returning to FastAPI, we mentioned that it’s built on the concept of concurrent programming. In addition, we know that it uses cooperative multitasking. Under the hood, it uses AnyIO which is a layer of extraction of both main Python’s concurrency standard libraries: asyncio (the one we ha...

Fortunately, Python tools like the ones we’re using don’t make those sorts of assumptions. When we’re working with table-type data, as long as the delimiter we specify matches what’s actually used in the file, the extension on the data file doesn’t matter either way. In fact, the...
We also have a dictionary(hasmap) formed from the historical dataset. The keys to this dictionary are the states which existed in the dataset. A value is an array of step counts for this state.This procedure gives the closest state with the most data points to our current state....
As an exercise, try to build a classifier using the same dataset but with either BoW or word embedding features and algorithms like logistic regression. Notice how long it takes for the individual steps of feature extraction and classification learning! When we have a large dataset, and when ...
