In this tutorial, you will learn –

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:

Install Python Library Linux

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.

Here are the steps to install XCode, HomeBrew as well as install Python 3 using HomeBrew onto your Mac: 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: $ xcode-select -install; Simply click through all the confirmation crap that XCode shows. The first step here is to properly install Python. When starting the installer for Python 3.5.1 (or later), be sure to select the installer option “Add Python 3.X to PATH”. This step is required! Next, start a Windows Command Prompt. If you know how to do this, skip ahead.

Install Python Go to the Python download page and download the package called Python 2.7.2 Mac OS X 64-bit/32-bit x86-64/i386 Installer. Double-click the downloaded.dmg file to install Python. Apr 18, 2018  The Command Prompt should be the first option that appears in the Start Menu. Right click on that option and choose Run as administrator. In the Command Prompt, type cd and a space and right-click in the Command Prompt to paste the path to Python. Type this command into the Command Prompt and press Enter. Jan 20, 2018  According to the pip installation documentation: “pip is already installed if you are using Python 2 =2.7.9 or Python 3 =3.4 downloaded from python.org or if you are working in a Virtual Environment created by virtualenv or pyvenv.” Open up your command prompt or terminal and enter: python -m pip install pandas. May 01, 2018  Pipenv the official recommended python packing tool is one of the easiest way to use virtual environment and installing python package together. Creating Virtual Environments¶. Python “Virtual Environments” allow Python packages to be installed in an isolated location for a particular application, rather than being installed globally. If you are looking to safely install global command line tools, see Installing stand alone command line tools.

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

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']

Python on a Macintosh running Mac OS X is in principle very similar to Python onany other Unix platform, but there are a number of additional features such asthe IDE and the Package Manager that are worth pointing out.

The Mac-specific modules are documented in Mac OS X specific services.

Python on Mac OS 9 or earlier can be quite different from Python on Unix orWindows, but is beyond the scope of this manual, as that platform is no longersupported, starting with Python 2.4. See http://www.cwi.nl/~jack/macpython forinstallers for the latest 2.3 release for Mac OS 9 and related documentation.

4.1. Getting and Installing MacPython¶

Mac OS X 10.8 comes with Python 2.7 pre-installed by Apple. If you wish, youare invited to install the most recent version of Python from the Python website(https://www.python.org). A current “universal binary” build of Python, whichruns natively on the Mac’s new Intel and legacy PPC CPU’s, is available there.

Mac Install Python Library Command In Windows 10

What you get after installing is a number of things:

  • A MacPython2.7 folder in your Applications folder. In hereyou find IDLE, the development environment that is a standard part of officialPython distributions; PythonLauncher, which handles double-clicking Pythonscripts from the Finder; and the “Build Applet” tool, which allows you topackage Python scripts as standalone applications on your system.

  • A framework /Library/Frameworks/Python.framework, which includes thePython executable and libraries. The installer adds this location to your shellpath. To uninstall MacPython, you can simply remove these three things. Asymlink to the Python executable is placed in /usr/local/bin/.

The Apple-provided build of Python is installed in/System/Library/Frameworks/Python.framework and /usr/bin/python,respectively. You should never modify or delete these, as they areApple-controlled and are used by Apple- or third-party software. Remember thatif you choose to install a newer Python version from python.org, you will havetwo different but functional Python installations on your computer, so it willbe important that your paths and usages are consistent with what you want to do.

IDLE includes a help menu that allows you to access Python documentation. If youare completely new to Python you should start reading the tutorial introductionin that document.

If you are familiar with Python on other Unix platforms you should read thesection on running Python scripts from the Unix shell.

4.1.1. How to run a Python script¶

Your best way to get started with Python on Mac OS X is through the IDLEintegrated development environment, see section The IDE and use the Help menuwhen the IDE is running.

If you want to run Python scripts from the Terminal window command line or fromthe Finder you first need an editor to create your script. Mac OS X comes with anumber of standard Unix command line editors, vim andemacs among them. If you want a more Mac-like editor,BBEdit or TextWrangler from Bare Bones Software (seehttp://www.barebones.com/products/bbedit/index.html) are good choices, as isTextMate (see https://macromates.com/). Other editors includeGvim (http://macvim.org) and Aquamacs(http://aquamacs.org/).

To run your script from the Terminal window you must make sure that/usr/local/bin is in your shell search path.

To run your script from the Finder you have two options:

  • Drag it to PythonLauncher

  • Select PythonLauncher as the default application to open yourscript (or any .py script) through the finder Info window and double-click it.PythonLauncher has various preferences to control how your script islaunched. Option-dragging allows you to change these for one invocation, or useits Preferences menu to change things globally.

4.1.2. Running scripts with a GUI¶

With older versions of Python, there is one Mac OS X quirk that you need to beaware of: programs that talk to the Aqua window manager (in other words,anything that has a GUI) need to be run in a special way. Use pythonwinstead of python to start such scripts.

With Python 2.7, you can use either python or pythonw.

4.1.3. Configuration¶

Python on OS X honors all standard Unix environment variables such asPYTHONPATH, but setting these variables for programs started from theFinder is non-standard as the Finder does not read your .profile or.cshrc at startup. You need to create a file~/.MacOSX/environment.plist. See Apple’s Technical Document QA1067 fordetails.

For more information on installation Python packages in MacPython, see sectionInstalling Additional Python Packages.

4.2. The IDE¶

MacPython ships with the standard IDLE development environment. A goodintroduction to using IDLE can be found athttps://hkn.eecs.berkeley.edu/~dyoo/python/idle_intro/index.html.

4.3. Installing Additional Python Packages¶

There are several methods to install additional Python packages:

  • Packages can be installed via the standard Python distutils mode (pythonsetup.pyinstall).

  • Many packages can also be installed via the setuptools extensionor pip wrapper, see https://pip.pypa.io/.

4.4. GUI Programming on the Mac¶

There are several options for building GUI applications on the Mac with Python.

PyObjC is a Python binding to Apple’s Objective-C/Cocoa framework, which isthe foundation of most modern Mac development. Information on PyObjC isavailable from https://pythonhosted.org/pyobjc/.

The standard Python GUI toolkit is Tkinter, based on the cross-platformTk toolkit (https://www.tcl.tk). An Aqua-native version of Tk is bundled with OSX by Apple, and the latest version can be downloaded and installed fromhttps://www.activestate.com; it can also be built from source.

wxPython is another popular cross-platform GUI toolkit that runs natively onMac OS X. Packages and documentation are available from http://www.wxpython.org.

PyQt is another popular cross-platform GUI toolkit that runs natively on MacOS X. More information can be found athttps://riverbankcomputing.com/software/pyqt/intro.

4.5. Distributing Python Applications on the Mac¶

The “Build Applet” tool that is placed in the MacPython 2.7 folder is fine forpackaging small Python scripts on your own machine to run as a standard Macapplication. This tool, however, is not robust enough to distribute Pythonapplications to other users.

The standard tool for deploying standalone Python applications on the Mac ispy2app. More information on installing and using py2app can be foundat http://undefined.org/python/#py2app.

4.6. Other Resources¶

The MacPython mailing list is an excellent support resource for Python users anddevelopers on the Mac:
