To install Python using Homebrew on macOS use brew install python3 at the Terminal prompt. Note On macOS, make sure the location of your VS Code installation is included in your PATH environment variable. Just click the Run Python File in Terminal play button in the top-right side of the editor. How to run a Python script¶. Your best way to get started with Python on Mac OS X is through the IDLE integrated development environment, see section The IDE and use the Help menu when the IDE is running. If you want to run Python scripts from the Terminal window command line or from the Finder you first need an editor to create your script. Installing Python 3 on Mac OS X¶ Mac OS X comes with Python 2.7 out of the box. If you perform a fresh install of Xcode, you will also need to add the commandline tools by running xcode-select-install on the terminal. While OS X comes with a large number of Unix utilities, those familiar with Linux systems will notice one key component.

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 6) Click Close button once install is done.

Step 7) Copy the path of your Scripts folder.

Step 8) In windows command prompt

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,

Enter command
Review the package upgrade, downgrade, install information and enter yes
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)

Enter the commands

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:

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.
You just have passed the regular Expression to the 'RegexpTokenizer' module.
Further, we tokenized the word using 'tokenize' module. The output is stored in the 'filterdText' variable.
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']

Email

As a popular open source development project, Python has an activesupporting community of contributors and users that also make their softwareavailable for other Python developers to use under open source license terms.

This allows Python users to share and collaborate effectively, benefitingfrom the solutions others have already created to common (and sometimeseven rare!) problems, as well as potentially contributing their ownsolutions to the common pool.

This guide covers the installation part of the process. For a guide tocreating and sharing your own Python projects, refer to thedistribution guide.

Note

For corporate and other institutional users, be aware that manyorganisations have their own policies around using and contributing toopen source software. Please take such policies into account when makinguse of the distribution and installation tools provided with Python.

Key terms¶

pip is the preferred installer program. Starting with Python 3.4, itis included by default with the Python binary installers.
A virtual environment is a semi-isolated Python environment that allowspackages to be installed for use by a particular application, rather thanbeing installed system wide.
venv is the standard tool for creating virtual environments, and hasbeen part of Python since Python 3.3. Starting with Python 3.4, itdefaults to installing pip into all created virtual environments.
virtualenv is a third party alternative (and predecessor) tovenv. It allows virtual environments to be used on versions ofPython prior to 3.4, which either don’t provide venv at all, oraren’t able to automatically install pip into created environments.
The Python Packaging Index is a publicrepository of open source licensed packages made available for use byother Python users.
the Python Packaging Authority is the group ofdevelopers and documentation authors responsible for the maintenance andevolution of the standard packaging tools and the associated metadata andfile format standards. They maintain a variety of tools, documentation,and issue trackers on both GitHub andBitbucket.
distutils is the original build and distribution system first added tothe Python standard library in 1998. While direct use of distutils isbeing phased out, it still laid the foundation for the current packagingand distribution infrastructure, and it not only remains part of thestandard library, but its name lives on in other ways (such as the nameof the mailing list used to coordinate Python packaging standardsdevelopment).

Changed in version 3.5: The use of venv is now recommended for creating virtual environments.

Basic usage¶

The standard packaging tools are all designed to be used from the commandline.

The following command will install the latest version of a module and itsdependencies from the Python Packaging Index:

Note

For POSIX users (including Mac OS X and Linux users), the examples inthis guide assume the use of a virtual environment.

For Windows users, the examples in this guide assume that the option toadjust the system PATH environment variable was selected when installingPython.

It’s also possible to specify an exact or minimum version directly on thecommand line. When using comparator operators such as >, < or some otherspecial character which get interpreted by shell, the package name and theversion should be enclosed within double quotes:

Normally, if a suitable module is already installed, attempting to installit again will have no effect. Upgrading existing modules must be requestedexplicitly:

More information and resources regarding pip and its capabilities can befound in the Python Packaging User Guide.

Creation of virtual environments is done through the venv module.Installing packages into an active virtual environment uses the commands shownabove.

How do I …?¶

These are quick answers or links for some common tasks.

… install `pip` in versions of Python prior to Python 3.4?¶

Python only started bundling pip with Python 3.4. For earlier versions,pip needs to be “bootstrapped” as described in the Python PackagingUser Guide.

… install packages just for the current user?¶

Passing the --user option to python-mpipinstall will install apackage just for the current user, rather than for all users of the system.

… install scientific Python packages?¶

A number of scientific Python packages have complex binary dependencies, andaren’t currently easy to install using pip directly. At this point intime, it will often be easier for users to install these packages byother meansrather than attempting to install them with pip.

… work with multiple versions of Python installed in parallel?¶

On Linux, Mac OS X, and other POSIX systems, use the versioned Python commandsin combination with the -m switch to run the appropriate copy ofpip:

Appropriately versioned pip commands may also be available.

On Windows, use the py Python launcher in combination with the -mswitch:

Common installation issues¶

Installing into the system Python on Linux¶

On Linux systems, a Python installation will typically be included as partof the distribution. Installing into this Python installation requiresroot access to the system, and may interfere with the operation of thesystem package manager and other components of the system if a componentis unexpectedly upgraded using pip.

On such systems, it is often better to use a virtual environment or aper-user installation when installing packages with pip.

Pip not installed¶

It is possible that pip does not get installed by default. One potential fix is:

There are also additional resources for installing pip.

Installing binary extensions¶

Python has typically relied heavily on source based distribution, with endusers being expected to compile extension modules from source as part ofthe installation process.
