Step by Step NLP in Python: An Overview of the Tutorials and Guides for Implementing NLP in Python

09 Mar 2023

As the field of Natural Language Processing (NLP) continues to grow, so does the interest in learning how to implement NLP using Python. This is because Python is one of the most widely used programming languages for NLP, due to its simplicity, readability, and vast range of libraries and tools. In this article, we will provide an overview of the tutorials and guides for implementing NLP in Python, and provide a step-by-step guide to help you get started with NLP in Python.

Understanding NLP

Before we dive into the tutorials and guides, it’s essential to understand what NLP is and what it entails. NLP is a subfield of artificial intelligence (AI) that focuses on enabling machines to understand, interpret, and generate human language. It encompasses various tasks, such as sentiment analysis, text classification, named entity recognition, machine translation, and more.

Tutorials for Implementing NLP in Python

There are several tutorials available online for learning NLP in Python. One of the most comprehensive and beginner-friendly tutorials is the “Natural Language Processing with Python” book by Steven Bird, Ewan Klein, and Edward Loper. This book is widely considered the standard introductory text for NLP in Python and covers a broad range of topics, including text processing, classification, and clustering.

Another excellent tutorial for implementing NLP in Python is the “NLP Tutorial” by Dipanjan Sarkar. This tutorial covers various NLP tasks such as tokenization, stemming, and sentiment analysis, among others. It also covers how to use popular NLP libraries such as NLTK, spaCy, and TextBlob.

For those interested in deep learning and NLP, the “Deep Learning for NLP” tutorial by Abhishek Thakur is an excellent resource. This tutorial covers deep learning architectures such as Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs) and how they can be used for NLP tasks.

Guides for Implementing NLP in Python

Besides tutorials, there are also several guides available that provide a comprehensive overview of NLP in Python. One of the most popular guides is the “Python NLP Libraries” guide by Machine Learning Mastery. This guide covers the most popular NLP libraries, including NLTK, spaCy, and TextBlob, and provides an overview of their features, capabilities, and limitations.

Another useful guide for implementing NLP in Python is the “Ultimate Guide to Natural Language Processing with Python” by Kavita Ganesan. This guide covers a wide range of NLP topics, including text preprocessing, feature engineering, and model building. It also covers the use of popular NLP libraries and tools.

Step-by-Step Guide for Implementing NLP in Python

Now that we’ve discussed the tutorials and guides available, it’s time to provide a step-by-step guide for implementing NLP in Python.

Step 1: Choose an NLP task

The first step is to choose an NLP task that you want to perform. This could be sentiment analysis, text classification, named entity recognition, or any other task that interests you.

Step 2: Choose an NLP library

Once you’ve chosen an NLP task, the next step is to choose an NLP library that you want to use. Some of the most popular NLP libraries are NLTK, spaCy, and TextBlob. Each library has its strengths and weaknesses, so it’s essential to choose one that best fits your needs.

Step 3: Preprocess the text

Before you can perform any NLP task, you need to preprocess the text. This involves tasks such as tokenization, stemming, and stopword removal. Most NLP libraries provide built-in functions for performing these  preprocessing tasks, so you don’t have to write the code from scratch.

Step 4: Extract features

Once the text is preprocessed, the next step is to extract features from the text. This could involve creating a bag-of-words model, using word embeddings, or other feature extraction techniques. The choice of features depends on the NLP task you

Step 5: Train the model

After feature extraction, you can train your NLP model. The process of model training involves splitting the data into training and testing sets, selecting the appropriate algorithm, and tuning the hyperparameters. The model’s performance can be evaluated using metrics such as accuracy, precision, recall, and F1 score.

Step 6: Test the model

Once the model is trained, it’s time to test it on unseen data. The model’s performance on the testing set can help you evaluate its generalization ability and identify areas for improvement.

Step 7: Deploy the model

Finally, you can deploy the NLP model in your application. This could involve creating a REST API, integrating the model with a chatbot, or other deployment methods.


In conclusion, NLP in Python is a vast field with a lot of resources available to learn and implement it. Whether you are a beginner or an experienced data scientist, there are tutorials and guides available that can help you learn NLP in Python. Additionally, implementing NLP in Python involves several steps, including choosing an NLP task, selecting an NLP library, preprocessing the text, extracting features, training the model, testing the model, and deploying the model.

By following the step-by-step guide we’ve provided, you can get started with NLP in Python and build your own NLP models. Keep in mind that NLP in Python is a constantly evolving field, so it’s essential to keep up with the latest developments and best practices to stay ahead of the curve.
