PyTest fixtures The purpose of test fixtures is to provide an inbuilt baseline ...

I’ve been playing around with the Yelp Open Dataset and wanted to extract more detailed location information for each business. This is an example of the JSON representation of one business: $ cat dataset/business.json | head -n1 | jq { "business_id": "FYWN1wneV18bWNgQjJ2GNg", "name": "Dental by Design", "neighborhood": "", "address": "4855 E Warner Rd, Ste B9", "city": "Ahwatukee", "state": "AZ", "postal_code": ...

If you already have installed Python, you may use IDLE which is ...

Some of you who follow me may have noticed a tendency of mine to “hack” programming languages more than really use them (other than reflection via annotations in languages such as Java; I hate that stuff), and today is no different. Today, we look as using what would be normal higher-order functions as Python decorators to create new functions that ...

In my post “Using gRPC in Python,” we wrote a basic gRPC server implementing a users service. We are going to expand on it and explore more gRPC concepts, such as secure client-server communication via self-signed SSL certificates, implementing gRPC middleware (or interceptors), and error handling. We will be using Python 3.6 for our demos in this article. The git ...

In my last blog post I showed how to create a multi class classification ensemble using scikit-learn’s VotingClassifier and finished mentioning that I didn’t know which classifiers should be part of the ensemble. We need to get a better score with each of the classifiers in the ensemble otherwise they can be excluded. We have a TF/IDF based classifier as ...

For the Kaggle Spooky Author Identification I wanted to combine multiple classifiers together into an ensemble and found the VotingClassifier that does exactly that. We need to predict the probability that a sentence is written by one of three authors so the VotingClassifier needs to make a ‘soft’ prediction. If we only needed to know the most likely author we ...
