### Top 5 Python Web Frameworks

**1) Django**

Django is a high-level Python Web framework that
encourages rapid development and clean, pragmatic design.

Ridiculously fast + Reassuringly secure +
Exceedingly scalable

**2) TurboGears**

TurboGears 2 is a reinvention of the TurboGears
project to take advantage of new components, and to provide a fully
customizable WSGI (Web Server Gateway Interface) stack.

**3)Web2Py**

Free open source full-stack framework for rapid
development of fast, scalable, secure and portable database-driven web-based
applications. Written and programmable in Python

**4) Flask**

Flask is a Python framework available under the BSD
license. It was inspired by the Sinatra Ruby framework. Flask depends on the
Werkzeug WSGI toolkit and Jinja2template.

**5)Bottle**

Bottle is a microframework. Originally meant for
building APIs, Bottle implements everything in a single source file. It has no
dependencies apart from the Python Standard Library. Coding with Bottle gets
you closer to the metal than coding with any full-stack framework.

### Top 6 NLP Python Library

**NLTK**- It is a leading platform for building Python programs to work with human language data. It provides easy-to-use interfaces to over 50 corpora and lexical resources such as WordNet, along with a suite of text processing libraries for classification, tokenization, stemming, tagging, parsing, and semantic reasoning, wrappers for industrial-strength NLP libraries, and an active discussion forum.

**TextBlob**- It is a Python (2 and 3) library for processing textual data. It provides a simple API for diving into common natural language processing (NLP) tasks such as part-of-speech tagging, noun phrase extraction, sentiment analysis, classification, translation, and more.

**Stanford CoreNLP**- It provides a set of human language technology tools. It can give the base forms of words, their parts of speech, whether they are names of companies, people, etc., normalize dates, times, and numeric quantities, mark up the structure of sentences in terms of phrases and syntactic dependencies, indicate which noun phrases refer to the same entities, indicate sentiment, extract particular or open-class relations between entity mentions

**spaCy**– The spaCy excels at large-scale information extraction tasks. It's written from the ground up in carefully memory-managed Cython. spaCy is the best way to prepare text for deep learning. It interoperates seamlessly with TensorFlow, PyTorch, scikit-learn, Gensim and the rest of Python's awesome AI ecosystem.

**Gensim**started off as a collection of Scalable statistical semantics and can analyze plain-text documents for semantic structure, retrieve semantically similar documents

**Polyglot**is a natural language pipeline that supports massive multilingual applications.
