11/3/2020 Can't Download Python Mac
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.
Some Mac users say that they can't download programs from other website except Mac App Store, or they may can't be opened the download file. When they click on the download file, it says 'xxx can't be opened because it is from an unidentified developer'.For example. You should never, ever install things into your system Python (especially in macOS) because you can risk to break your system entirely. That's because Python is used by the operating system to run certain things, so it's better to leave it alone. The simplest way to install Spyder in macOS is to download Anaconda and install it. Homebrew would need to do two separate compiles of OpenCV for Python 2.7 and Python 3 as they are two entirely different Python versions and will thus bind with OpenCV differently. As the current Homebrew formula stands, it looks like you can compile Python 2.7 bindings, but there is a bug with the Python 3 bindings.

The Finder menu bar also provides quick access to the Mac Downloads folder. From anywhere in the Finder, simply pull down the “Go” menu and choose “Downloads” If you prefer to use keystrokes, you can hit Command + Option + L within the Finder to jump to the Downloads folder as well. Go to Downloads Folder from Finder Sidebar.
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:
Downloading and Installing the Booksite Library
Perform these steps to download and install the booksite library:
Perform these steps to test your installation of the booksite library:
Configuring 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. 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?
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?
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.
