How to Download all packages of NLTK. Step 1)Run the Python interpreter in Windows or Linux. Step 2) Enter the commands; import nltk nltk.download NLTK Downloaded Window Opens. Click the Download Button to download the dataset. This process will take time, based on your internet connection. Let’s install a real version of Python. Before installing Python, you’ll need to install a C compiler. The fastest way is to install the Xcode Command Line Tools by running xcode-select -install. You can also download the full version of Xcode from the Mac App Store, or the minimal but unofficial OSX-GCC-Installer package.

Before we jump into the deep learning or artificial intelligent topics, we need to have Python installed first. The following steps are walk through on how to install Python. We are going to use Anaconda Python. It will be pretty much the same for PC users or MAC users. Steps to Install Python (Anaconda) for PC and MAC. Python's syntax allows developers to use fewer lines of code than any other programming language. It basically focuses on the code readability of program. Python 2.7 is installed by default on MacOS but we can install other versions like python 3.5 and 3.6. In this tutorial, we are learning how to install Python 3.6.3 on the MAC Operating system. Install Python Python may be installed on your Mac already: you can test this out by opening Terminal and entering python -version. If it's not, you should make your way to the Python website. This short tutorial will show you how to properly install Python 3 on a Mac OS X computer. There are multiple ways to install Python 3, including a download from the official Python site, however I strongly recommend instead using a package manager like Homebrew to manage all your dependencies going forward. It will make your life a lot simpler. If you are using a Mac, see the Python for Mac OS X page. MacOS since 10.2 (Jaguar) include a system version of Python, but it is best not to consider this the Python to use for your programming tasks - install a current Python instead. 10.15 (Catalina) is the last MacOS to include a default system Python, as Apple have now deprecated this.

Installing NLTK in Windows

In this part, we will learn that how to make setup NLTK via terminal (Command prompt in windows).

The instruction given below are based on the assumption that you don't have python installed. So, first step is to install python.

Installing Python in Windows:

Step 1) Go to link https://www.python.org/downloads/, and select the latest version for windows.

Note: If you don't want to download the latest version, you can visit the download tab and see all releases.

Step 2) Click on the Downloaded File

Step 3)Select Customize Installation

Step 4) Click NEXT

Step 5) In next screen

1. Select the advanced options
2. Give a Custom install location. In my case, a folder on C drive is chosen for ease in operation
3. Click Install

Step 6) Click Close button once install is done.

Step 7) Copy the path of your Scripts folder.

Step 8) In windows command prompt Mac os x default download location.

• Navigate to the location of the pip folder
• Enter command to install NLTK
• Installation should be done successfully

NOTE: For Python2 use the commandpip2 install nltk

Step 9) In Windows Start Menu, search and open PythonShell

Step 10) You can verify whether the installation is accurate supplying the below command

If you see no error, Installation is complete.

Installing NLTK in Mac/Linux

Installing NLTK in Mac/Unix requires python package manager pip to install nltk. If pip is not installed, please follow the below instructions to complete the process

Step1) Update the package index by typing the below command

Step2) Installing pip for Python 3:

You can also install pip using easy_install.

Now easy_install is installed. Run the below command to install pip

Step3)Use following command to install NLTK

Installing NLTK through Anaconda

Step1) Please install anaconda (which can also be used to install different packages) by visiting https://www.anaconda.com/download/ and select which version of python you need to install for anaconda.

Note: Refer to this tutorial for detailed steps to install anaconda

Step 2)In the Anaconda prompt,

1. Enter command
2. Review the package upgrade, downgrade, install information and enter yes
3. NLTK is downloaded and installed

NLTK Dataset

NLTK module has many datasets available that you need to download to use. More technically it is called corpus. Some of the examples are stopwords, gutenberg, framenet_v15, large_grammarsand so on.

How to Download all packages of NLTK

Step 1)Run the Python interpreter in Windows or Linux

Step 2)

1. Enter the commands

2. NLTK Downloaded Window Opens. Click the Download Button to download the dataset. This process will take time, based on your internet connection

NOTE: You can change the download location by Clicking File> Change Download Directory

Step 3) To test the installed data use the following code

['The', 'Fulton', 'County', 'Grand', 'Jury', 'said', ..]

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']

Being a software engineer, you often come across many instances where you would require to have Python installed on your Mac.

However, the issue is most modern macOS versions come with rather with Python 2.7.x installed and not the newer, modern version like Python 3.6.5 or Python 3.7.2 (which is the most up-to-date version right now).

This short guide is written to show you how to properly install Python 3 on a Mac OS Xcomputer.

Before you jump into the guide, do take note that there are multiple ways to install Python 3 on a Mac but with this guide, I’ll show you the two easiest ways to do this, step-by-step.

Personally, the way I did it was using a package manager like HomeBrew (it’s okay if you don’t understand what it is). Again, I’ll show you how to do this method down below.

Wait, how do I check if Python 3 is already installed on my Mac?

Simple. Open up your Terminal and type the following line python --version and then hit your Enter key:

You should see the python version that is currently installed on your Mac.

How to Install Python 3 on macOS: 2 Ways

1. The Simplest Way.

Perhaps the simplest way to install Python 3 on macOS.

This is for you especially if you’re a newbie (though I still strongly recommend you try the HomeBrew method below) or if you don’t want to deal with copy-pasting code into your Terminal and downloading other software.

Here’s how to install Python 3 on your macOS:

1. Jump into Python.org downloads page and simply just download the latest Python version.

2. Next, run the Python Installer to install Python 3 onto your Mac.

Note

The Python installation may require about 100MB of disk space to install. Once you’ve installed Python 3 you can have it alongside Python 2 without having to delete the latter from your Mac.

3. Great! Now once Python 3 is installed, you’ll be able to find it within the Applications directory of your Mac. You’ll also find here a simple IDE called “IDLE.app” which gives you a basic Python IDE.

Help! Where do I find the Applications directory?

If you can’t find the Applications directory, simply go to Finder by clicking the Finder icon in the Dock (it’s usually the first icon from the left side of the Dock). From there simply, go to the Go menu and select Applications.

Done. If you got yourself lost through the process, you can comment down below.

Next up, I’ll show you how you can install Python 3 using HomeBrew onto your macOS. This is my preferred way and it is just as simple as the method before but it will make your life a whole lot simpler, in the long run, using Python.

2. Install Python 3 on Mac using HomeBrew.

This method is dead-ass simple and a little fun. 🙂

First of all, you’ll need to have this thing called HomeBrew installed on your Mac. Homebrew is basically a “package manager”. A package manager is an application that helps you install the stuff you need that Apple (or even your Linux System) hadn’t installed in the first place for you.

It’s simple, fast and safe.

Second, you will need to have installed XCode onto your Mac. If you’re thinking of learning how to program or creating iOS apps on your Mac, then it’s good to have XCode installed. We will be using XCode to install HomeBrew application.

Note

If you have already installed XCode onto your Mac you can skip step 1 and jump straight to step 3.

Here are the steps to install XCode, HomeBrew as well as install Python 3 using HomeBrew onto your Mac:

1. Jump into your Terminal app on your Mac and run the copy/paste the following command into the Terminal to install XCode onto your Mac:
   
2. Simply click through all the confirmation crap that XCode shows. It may take a little while to install XCode since it is a large program.
3. Great! Now that you have XCode installed, you can install HomeBrew! To install HomeBrew, simply copy/paste the following command into your Terminal:

Note

You can confirm the HomeBrew installed correctly by running the command: below:

4. You’ve installed HomeBrew! Now let’s install the Python 3, the reason why you’re here. To install the latest version of Python, just copy/paste the following command into your Terminal:
   

Note

You can confirm which version of Python was installed all by running the command below (the exact same command you tried earlier in this guide). It should show up as follows:

5. Finally, let’s run our new Python 3. Simply enter python3.

Voila! You have now installed Python 3 successfully if you see something similar in your Terminal:

Bonus

•If you want to exit, type exit() and then hit your Return button on your keyboard. You can also hit both Control and D keys at the same time instead of the Return key.

•Remember I mentioned you can run both your new Python 3 alongside your old Python 2? Yup. Simply type python into the Terminal to run with Python 2.
