With over 250 libraries in Python, it can be a bit confusing to know which one is best for your project. In this article, we have deeply explained which Python library is best for which type of project.
So in this article, We are going through the top 40 libraries that we think you should know about. Natural Language Processing is a field that combines linguistics and computer science. It allows computers to process and analyze the natural language toolkit or NLT.
List of All the Most Used Python Libraries
- OpenCV Python
NLTK is one of the most popular natural language processing libraries. It allows you to perform various operations in the English language like tokenizing tagging in stemming; you can tokenize words or sentences, which separates words in a sentence or sentences in a paragraph.
For example, it is tokenizing this since New York muffins output a list of strings with each word as a separate string. Now you can tag each word of a tokenize sentence with a part of the speech label. This will output a tuple for each word, followed by its part of speech. And NP, which stands for proper noun singular, is the tag for John. You can also stem words, the stem of a word maximum is maximum, and the stem presumably is presumed. It is important to note that there are several different methods to stemming, and each will produce different outputs based on its unique algorithm.
By combining the basic functionalities of NLTK, you can develop more complex programs like the stock site.
Gensim is another Python natural language processing library. Its target audience is the natural language processing and information retrieval communities.

24. Psychic – Python Library For Healthcare
Psychic learn an open-source commercially usable Python library for working with complex data. It has six main components. Classification, identifying which category and option belong to regression, predicting a continuous-valued attribute associated with an object. Automatic clustering grouping similar objects into sets reduces dimensionality, reduces the number of random variables to consider model selection, comparing validating and choosing parameters and models. And they are finally pre-processing feature extraction in normalization. Imbalanced data sets describe situations where class distribution is not uniform and can lead to problems if not accounted for properly.
For example, the classification model you’re working on has an accuracy of 80%; however, you discover that 80% of the data belongs to one class. Imbalance learn is a Python package that offers several resampling techniques commonly used for correcting imbalanced data sets like this.
It’s compatible with psychic learning and is part of the psychic learning projects.
