Identifying the gender

Identifying the gender of a name is an interesting task in NLP. We will use the heuristic that the last few characters in a name is its defining characteristic. For example, if the name ends with "la", it's most likely a female name, such as "Angela" or "Layla".

How to do it…

1. Create a new Python file, and import the following packages:

   import random
   from nltk.corpus import names
   from nltk import NaiveBayesClassifier
   from nltk.classify import accuracy as nltk_accuracy

2. We need to define a function to extract features from ...
