When installing Python, you’ll also set up a shortcut for the IDLE program, which is the IDE (Integrated Development Environment that lets you write programs for Python. Installing Python 3 on Mac OS X. The version of Python that ships with OS X is great for learning, but it’s not good for development. The version shipped with OS X may be out of date from the official current Python release, which is considered the stable production version. As with just about any open source software package, there are quite a few ways to install Python on Mac OSX. I figured it would be helpful to detail a few of the easiest ways to install Python, including the following: These are the most commons you'll encounter, and each method has its own purpose.

Running the NLP Script

We are going to discuss how NLP script will be executed on our local PC. There are many libraries for Natural Language Processing present in the market. So choosing a library depends on fitting your requirements. Here is the list of NLP libraries.

How to Run NLTK Script

Step1) In your favorite code editor, copy the code and save the file as 'NLTKsample.py '

Code Explanation:

  1. In this program, the objective was to remove all type of punctuations from given text. We imported 'RegexpTokenizer' which is a module of NLTK. It removes all the expression, symbol, character, numeric or any things whatever you want.
  2. You just have passed the regular Expression to the 'RegexpTokenizer' module.
  3. Further, we tokenized the word using 'tokenize' module. The output is stored in the 'filterdText' variable.
  4. And printed them using 'print().'

Step2)In the command prompt

  • Navigate to the location where you have saved the file
  • Run the command Python NLTKsample.py

This will show output as :

['Hello', 'Guru99', 'You', 'have', 'build', 'a', 'very', 'good', 'site', 'and', 'I', 'love', 'visiting', 'your', 'site']
