Download Python 3.6.2 Latest Version – Python 3.6.2 is a dynamic object-oriented programs language that can be made use of for several sort of software program development. It supplies strong assistance for combination with various other languages and also devices, features extensive common collections, and also can be learned in a couple of days.
- See the Python for Mac OS X page. MacOS since 10.2 (Jaguar) includes 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 version instead. 10.15 (Catalina) is the last MacOS to include a default system Python, as Apple has now deprecated this.
Python is a popular programming language that is widely used by beginners and longtime developers alike. Modern Mac OS versions come with Python 2.7.x installed (or Python 2.6.1 if an older Mac OS X version), but many Python users may need to update Python in Mac OS to a newer version like Python 3. Com/quicklinks and type in ‘Python’, then click on ‘Download Python from the official Python.org website’. This should automatically take you to the Mac® version of the page. If not, click on ‘Mac OS X’, MAC® circled above. Click on the ‘Download Python 3.6.0’ button. The download will start automatically. 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.

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']
This page tells you how to setup a Python programming environment for your Mac OS X computer and provides a step-by-step guide for creating and running a simple 'Hello, world' Python program. All of the software is freely available on the Web. These instructions are for MacOS X 10.13 (High Sierra), but the instructions for other recent versions of Mac OS X are similar.
Overview
The Python programming environment required by this booksite consists of:
- Python, that is, the Python compiler/interpreter.
- The Python standard libraries.
- IDLE, the Python Integrated DeveLopment Environment.
- The Tkinter, NumPy, and Pygame libraries, which are used by the booksite programs that do graphics or audio processing.
- The booksite library, that is, a set of modules that we developed specifically to support this booksite.
- The Terminal application that is bundled with Mac OS X.
Downloading and Installing Python, IDLE, Tkinter, NumPy, and Pygame
Note: The Mac Finder application uses the term folder to mean a container of documents and, perhaps, other folders. This document instead uses the equivalent Unix term directory. |
Python 2 is bundled with Mac OS X. However, Python 3 is not. We recommend that you download and install Python 3, and use Python 3 exclusively when running programs associated with this booksite.
Perform these steps to download and install Python, IDLE, Tkinter, NumPy, and PyGame:
- Browse to the Python for Mac download page.
- In the resulting page click on the Download Python 3.6.5 button. Your browser will download the file
python-3.6.5-macosx10.6.pkg
to yourDownloads
directory. - Using Mac Finder Manager, navigate to your
Downloads
directory, and double-click on thepython-3.6.5-macosx10.6.pkg
file to install Python, Tkinter, and IDLE. Use the default options. (It's OK to delete thepython-3.6.5-macosx10.6.pkg
file after the installation is complete.) - Open a Terminal window. To do that, click on the Spotlight Search icon on the right end of the menu bar. (It has the appearance of a magnifying glass.) In the resulting dialog box, type
Terminal.app
followed by the Enter key. - In the Terminal window issue these commands to install NumPy and PyGame:
To 'issue a command' you should type the command followed by the Enter key. |
Perform these steps to test your installation:
- In the Terminal window issue the
python3
command. You should see something like this: - If you see that output, then your installation of Python, IDLE, and Tkinter was successful.
- At the Python
>>>
prompt, typeimport numpy
followed by theEnter
key. If no error messages appear, then your installation of NumPy was successful. - At the Python
>>>
prompt, typeimport pygame
followed by theEnter
key. If no error messages appear, then your installation of PyGame was successful. - At the Python
>>>
prompt, typeexit()
followed by theEnter
key to exit Python. - In the Terminal window issue the command
idle3
. If an IDLE window appears, then you have installed IDLE properly. Close the IDLE window. - Close the Command Prompt window.
IMPORTANT: When running the Python programs associated with this booksite, do not issue the python command. Instead issue the python3 command. The former command runs the Python 2 compiler/interpreter that is bundled with Mac OS X; the latter command runs the Python 3 compiler/interpreter that you installed by following the instructons on this page. |
Downloading and Installing the Booksite Library
Perform these steps to download and install the booksite library:
- Use your Web browser to download this introcs-1.0.zip file to your
/Users/yourusername/Downloads
directory. - In the Finder, double click on
/Users/yourusername/Downloads/introcs-1.0.zip
to unzip the file, thus creating a directory named/Users/yourusername/Downloads/introcs-1.0
. (It's OK to delete the/Users/yourusername/Downloads/introcs-1.0.zip
file after you have unzipped it.) - Open a Terminal window.
- At any time the Terminal application has a working directory. Initially the working directory is
/Users/yourusername
. In the Terminal window issue thecd Downloads
command to change your working directory to/Users/yourusername/Downloads
, and then issue thecd introcs-1.0
command to change your working directory to/Users/yourusername/Downloads/introcs-1.0
. (Incidentally, thecd .
command changes your working directory to the 'parent' of the current working directory.) - Issue the
ls
command to display the names of all files in your working directory. Make sure that a file namedsetup.py
is in your working directory. - Issue the
python3 setup.py install --user
command. The computer copies the files defining the booksite modules to a directory where Python can find them, and writes status messages to your Terminal window to indicate its progress.
Perform these steps to test your installation of the booksite library:
- In the Terminal window issue the
python3
Command and conquer for mac. command. - At the Python
>>>
prompt, type the statementimport stdio
followed by the Enter key. If Python generates no error messages, then you have installed the booksite library properly. - At the Python
>>>
prompt, typeexit()
Xvid codec download for mac quicktime. followed by the Enter key to exit Python. - Close the Terminal window.
Configuring IDLE
So far you've downloaded and installed all of the software that you'll need. Word doc for mac. You should perform one more step before creating your first program: configure the IDLE programming environment. Follow these instructions:
- Open a Terminal window.
- In the Terminal window issue the command
idle3
to launch IDLE. - Click on the Python → Preferences.. menu item.
- Click on the General tab.
- Click on the Open Edit Window radio button.
- Click on the Ok button.
- Close the IDLE window.
- Close the Terminal window.
Composing Your First Program
Having installed Python, the Python standard libraries, IDLE, Tkinter, NumPy, Pygame, and the booksite libraries, and having configured IDLE, you are ready to compose your first Python program. Perform these instructions:
- Using the Mac Finder, create a directory named
/Users/yourusername/hello
. - Open a Terminal window.
- Issue the
cd hello
command to make the/Users/yourusername/hello
directory your working directory. - Issue the command
idle3 &
to launch IDLE. Note the trailing ampersand. The trailing ampersand tells the computer to run theidle3
program in the background, thereby leaving your Terminal application free to handle additional commands while IDLE is running. - In IDLE, type the four-line Python program helloworld.py exactly as it appears below. Use the arrow keys, mouse, or touchpad to move within the text that you have typed. Use the Delete key to delete text. Be careful; the smallest typing mistake might cause the program to fail.
- When you are finished typing, in IDLE click on the File → Save.. menu item to save the Python program. Save it in a file named
helloworld.py
in the directory/Users/yourusername/hello
. The file name is case sensitive, so make sure you use all lowercase letters.
Running Your First Program
The final step is to run your program. It is possible to run some Python programs from within IDLE, but you should run the programs associated with this booksite directly from a Terminal window. To do that, perform these steps:
- Within the same Terminal window, issue the
ls
command to display the names of all files in the working directory. Confirm that the working directory contains yourhelloworld.py
Visual boy advance for mac. file. - Issue the
python3 helloworld.py
command to run your program. If the computer writes 'Hello, World' to the Terminal window, then the execution of yourhelloworld.py
program was successful. If the computer instead writes error messages, then use IDLE to correct your program, and issue thepython3 helloworld.py
command again. Repeat until your program runs successfully. If your program runs successfully the first time you try, then intentionally introduce an error into your program, just so you get some experience with correcting errors. - Close the IDLE window.
- Close the Terminal window.
You now have installed and configured a reasonable Python environment, and have used it to compose and run a Python program. Congratulations! You are a Python programmer!
Downloading the Booksite Example Programs (optional)
We recommend that you download the booksite example programs, that is, the example Python programs that are presented incrementally throughout the booksite. Having done so, you can run those programs to help you learn about them. Perform these instructions:
- Use your Web browser to download this introcs-python.zip file to your
/Users/yourusername/Downloads
directory. - In the Mac Finder, double-click on
/Users/yourusername/Downloads/introcs-python.zip
to unzip the file, thus creating the/Users/yourusername/Downloads/introcs-python
directory containing the booksite example programs. (It's OK to delete the/Users/yourusername/Downloads/introcs-python.zip
file after you have unzipped it.)
Then perform these steps to test your download of the booksite example programs:
- Open a Terminal window.
- Issue the
cd Downloads
andcd introcs-python
commands to make/Users/yourusername/Downloads/introcs-python
your working directory. - Issue the
ls
command. Confirm that the working directory contains a file namedbouncingball.py
. - Issue the
python3 bouncingball.py
command. If Python launches a stddraw window showing an animated bouncing ball, then your download of the booksite example programs was successful. - Close the stddraw window.
- Close the Terminal window.
Downloading the Booksite Example Data (optional)
We recommend that you download the booksite example data, that is, the data files used by the booksite example programs that are presented incrementally throughout the booksite. Perform these instructions:
- Use your Web browser to download this introcs-data.zip file to your
/Users/yourusername/Downloads
directory. - In the Finder, double-click on
/Users/yourusername/Downloads/introcs-data.zip
to unzip the file, thus creating the/Users/yourusername/Downloads/introcs-data
directory containing the booksite example data files. (It's OK to delete the/Users/yourusername/Downloads/introcs-data.zip
file after you have unzipped it.)
Downloading the Booksite Library: Part 2 (optional)
Python 3.6 Download For Mac
Previously on this page we described how to download and install the booksite library so Python can find it. Now we describe how to download the booksite library so you can find it — for the sake of studying the code that implements it, should you so desire. Perform these instructions:
- Use your Web browser to download this stdlib-python.zip file to your
/Users/yourusername/Downloads
directory. - In the Mac Finder, double-click on
/Users/yourusername/Downloads/stdlib-python.zip
to unzip the file, thus creating the/Users/yourusername/Downloads/stdlib-python
directory containing the booksite library. (It's OK to delete the/Users/yourusername/Downloads/stdlib-python.zip
file after you have unzipped it.)
We invite you to study the code that implements the booksite library. But don't be concerned if some of the code is cryptic. The code that implements the booksite library uses some features of Python that are beyond the scope of the textbook and this booksite.

Eclipse For Mac
Q. Must I use IDLE to create my Python programs? Can I use some other text editor?
Download Python For Machine Learning
A. You need not use IDLE to create your Python programs; it is fine to use some other text editor. For example, it is reasonable to use the TextEdit editor that is bundled with Mac OS X. However if you do use some other text editor, then make sure you change its settings so it (1) uses a four-space indentation scheme, and (2) indents using spaces instead of tabs. The Wikipedia Comparison of text editors page provides summary descriptions of many text editors.
