Currently, he develops software for the financial services industry and leads classes and workshops in Python at PracticalProgramming.co Python Fundamentals Live Stream Python fundamentals is an interactive 1.5-hour live python programming webinar for beginners. OS X (Mavericks) has Python 2.7 stock installed. But I do all my own personal Python stuff with 3.3. I just flushed my 3.3.2 install and installed the new 3.3.3. So I need to install pyserial again. I can do it the way I've done it before, which is: Download pyserial from pypi.

How can I change the default version to Python 3.5 for Terminal use? Stack Overflow. The easiest way is to download the Mac installer. For Brew, kindly refer to the document, Installing Python on Mac OS X. It has a step-by-step guide to help you through the entire process of installing python 3. Jun 13, 2018.
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.
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 3 from the Pythonwebsite (http://www.python.org). A current “universal binary” build of Python,which runs natively on the Mac’s new Intel and legacy PPC CPU’s, is availablethere.
What you get after installing is a number of things:
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. Pathfinder ultimate intrigue pdf download free.
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.shtml) are good choices, as isTextMate (see http://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: How to download sister location for free.
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 3.3, 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 for details.
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 athttp://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:
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 http://pyobjc.sourceforge.net.
The standard Python GUI toolkit is tkinter, based on the cross-platformTk toolkit (http://www.tcl.tk). An Aqua-native version of Tk is bundled with OSX by Apple, and the latest version can be downloaded and installed fromhttp://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 athttp://www.riverbankcomputing.co.uk/software/pyqt/intro.
4.5. Distributing Python Applications on the Mac¶
The “Build Applet” tool that is placed in the MacPython 3.3 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:
Another useful resource is the MacPython wiki:
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:
Downloading and Installing Python, IDLE, Tkinter, NumPy, and Pygame
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:
Perform these steps to test your installation:

Download Python For Mac OsConfiguring IDLE
So far you've downloaded and installed all of the software that you'll need. You should perform one more step before creating your first program: configure the IDLE programming environment. Follow these instructions:
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:
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:
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:
Then perform these steps to test your download of the booksite example programs:
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:
Downloading the Booksite Library: Part 2 (optional)
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:
We invite you to study the code that implements the booksite library. But don't be concerned if some of the code is cryptic. https://computeryellow665.weebly.com/chief-architect-mac-free-download.html. The code that implements the booksite library uses some features of Python that are beyond the scope of the textbook and this booksite.
Q & A
Q. Why do I get the error
ImportError: No module named stdio when I issue the command python program_that_uses_stdio.py ?
A. You must issue the command
python3 program_that_uses_stdio.py , as described above.
Q. I downloaded files using my browser, but can't find them. Where are they?
A. Many browsers by default place downloaded files in the directory
/Users/yourusername/Downloads .
Q. How do I break out of an infinite loop when running my program from the Terminal application?
All2mp3 converter free download mac. A. Type Ctrl-c. That is, while pressing the Ctrl key, type the c key.
Q. Must I use IDLE to create my Python programs? Can I use some other text editor?
Python 3 Mac Os
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.
