Python 3 For Windows Phone is a Windows Phone 8 app that provides an interactive Python shell. You can run scripts either interactively, by typing them into the bottom window, or run. Remember that running python pyinstaller.py myscript.py assumes that you have Python in your path environment variable. If that is not the case, just use C: Python27 python.exe pyinstaller.py myscript.py in Windows. Most of the time on Linux and Mac OS X, Python will be in your path environment variable.

When you get a brand-new Mac, you might assume it’s loaded up with brand-new software. https://evcuiqc.weebly.com/blog/delete-old-ios-apps-from-mac. And for most apps, you’d be right. For underlying frameworks, however, it’s a different story. Brand-new Macs fresh from the factory floor still ship with Python 2.7.10, even though the most recent stable release is Python 3.6.1. This might seem like a pretty significant gap between versions, and that’s because it is. But newer isn’t always better. Python 2 is still the default language, but that’s likely to change in the coming years.
2to3 or not 2to3?
It’s natural think that Python 3 is better because it’s newer. They wouldn’t be totally wrong: Python 3 includes some cool new features that Python 2 lacks. However, alongside those new features, Python 3 also has a problem. It’s not backwards compatible with Python 2. That means that programs written for a Python 2 interpreter won’t run on a Python 3 interpreter. Even fundamental commands like
print and integer comparison work differently between Python 2 and 3, complicating the process of moving from one language to another. You can check out a list of the most significant changes on the Python 3.0 documentation.
But why hasn’t the whole world switched over to Python 3? The main problem is that there’s a lack of compelling motivation. https://weceya.weebly.com/mysql-mac-download-107.html. Python 2 is a strong language, and only power users will get to experience the full benefit of Python 3’s new features. Plus, Python 2.7.10 is pre-installed on all Macs and a number of Linux distros. With the significant differences between the two versions and the work required to convert from 2 to 3, it’s hard to find strong reasons to move Python 2 apps to Python 3. It’s true that utilities like 2to3 make it easier to transform a Python 2 program into valid Python 3 syntax, but if you’ve ever used Google Translate, you know this won’t be perfect.
Unfortunately, Python 2 isn’t going to be around forever. The developers have set 2020 as the final year for Python 2 support, and everyone will need to transition their programs over to Python 3 by then. If you’re writing new programs in Python, you might be interested in starting to use Python 3. But first, you’ll need to install a Python 3 interpreter on your Mac.
Upgrading to Python 3 on your Mac
Even if it isn’t the de facto standard, you can run Python 3 on your Mac today. You can even run it alongside a concurrent Python 2.7 installation without affecting the version 2.7 installation.
1. Download the most recent package from the Python website.
2. Double-click the downloaded package and run the Python installer.
3. Once the installer is finished, you’ll find a new Python 3.6.1 folder inside of the Applications directory. The installer also installed the Python interpreter and binaries in your /usr/local/bin folder.
4. This folder contains a GUI for launching Python applications called Python Launcher. It also includes IDLE, an IDE for developing Python applications, a link to Python’s documentation and miscellaneous documents.
Launching Python 3 from the Terminal
1. If you want to run a Python 3 script or application from the command line, you’ll need to use the command
python3 . Notice the difference when compared to the python command, which runs Python 2.7. If you end up using Python 3 as your primary interpreter, you can change this alias, but python3 is the default.
Mail app not opening on mac. 2. Without additional arguments, the
python3 command will invoke the Python 3 interactive interpreter. This allows you to type Python 3 code into the Terminal and run it on a line-by-line basis.
3. If you do something a little more useful and run a script with the Python 3 interpreter, follow the
python3 command with the path to your .py file.
Launching Python 3 from the GUI
You can also run Python 3 programs from the Python Launcher GUI.
1. Open the Python Launcher found in “/Applications/Python 3.6.1.” (Note that the version number in the Python folder’s name will change with future versions of Python. Just look for the one that starts with a 3.)
2. This opens the Preferences window for the launcher. The application is set to run everything with a Python 2 interpreter by default, but we can change that. Change the path under “Interpreter” to “/usr/local/bin/python3”, which is the default directory of the Python 3 interpreter.
3. Chose “File > Open…” from the menu bar. Then, select the Python program you want to run.
4. The selected program will now run. GUI programs will launch their visual interface, and scripts will run in the Terminal window.
You can also run Python programs with the GUI by adding the Python launcher icon to your Dock and dragging Python scripts on top of it.
Conclusion
Getting Python 3 running on your Mac ins’t hard. However, changing your coding habits can take some time. If you’ve been writing Python 2 for a while now, switching to Python 3 can be a tedious and frustrating process. You’ll have to update your knowledge eventually, however, so you may as well get started now, while you’ve got a couple of years ahead of you.

While the Python language changes slowly, operating systems and setup methods changemore rapidly with succeeding versions.The attempt here is to keep all such information in one place for the Mac OS-X operating system.It may become out of date at any time.
Most stable os x for hackintosh. I will assume a version of Max OSX of at least High Sierra (10.13 or later). Upgrades are free.
5.3.1. Versions¶
I will use Python 3.8+ to mean the current version of Python, with version number at least3.8.1.Make sure you have the latest recommended version installed from https://www.python.org/downloads/.Download the pkg file and double click to execute.
5.3.2. Editing by Default in Idle¶
You will be working mostly with files ending in .py – Python source files.Most of the time you will be editing them and running them in IDLE, so the bestdefault behavior when opening a file with extension .py is to have it open inIdle 3.8+. If you can double click on a .py file in my examples,and Idle opens as soon as you have installed Python 3.8+, great - you should skip the rest of this section.
https://greatstaff511.weebly.com/update-firmware-macproefiupdatedmg-how-to.html. If Idle did not open, here is how to change the default behavior:
5.3.3. Running Graphics (Chapter 2)¶Running Mac Apps Under Python 3.0
The graphics window likely comes up behind an unneeded Console Window. You canclose the console window, and click on the graphics window title bar tobring it to the front.
5.3.4. Chapter 4 CGI Instructions¶5.3.4.1. Opening .cgi Files in Idle¶
By convention the server programs that you will be writing end in ”.cgi”.That is not an extension that is automatically associated with Idle for editing.You will want to change the association. Do it the same way as the instructionsabove for getting .py files to open in Idle by default, except choose a .cgi file in my wwwfolder, and go through the same procedure.
5.3.4.2. Setup: Making CGI Scripts Executable¶
A complication on a Mac, like any Unix derived system, is that programsthat you run must be explicitly marked executable. (On Windows it follows fromthe file extension, like .exe.) The examples/www folder may nothave the cgi files marked executable (nor have several other technical things right).
https://evcuiqc.weebly.com/blog/downie-mac-app-cracked. The example program examples/www/CGIfix.py is used to give directUnix/Mac/Linux executability to CGI files for Chapter 4.
In the finder open your www directory. You can open CGIfix.py in Idle and run it.Note the comment that the file
cgiServerScript https://clevertransfer967.weebly.com/12-33-stardew-valley-mac-download.html. was created.This is used to lauch the local server.
Important! Particularly if you later copy in a CGI script from a Windowsmachine, or if you create any new cgi script in the www directory, make sureit becomes executable (and possibly fix some other technical things) bylaunching CGIfix.py again.
If you forget this, and the file is not executable,nothing happens in the browser when you try to run it,and the error message in the server window is very unhelpful -it says ”. File not found .”. Make sure you make new CGI filesexecutable (with CGIfix.py)! Running it extra times does not hurt.
5.3.5. Terminal Use (Optional)¶
To use the Hands-on Python Tutorial, the information above should be sufficientto get your Mac usage going. Terminals are quite useful in other contexts:There are many things that can bedone from such a window that cannot be done from the Finder or with an App.
If you would like a bit more background, read on.
5.3.5.1. Navigation¶
OS X and Unix (from which OS X is derived)have a concept of the current directoryDirectory is the older term for folder from when there were not pictures offolders in a graphical interface.
You start in your home directory. My login id is anh, so my home directory is
/Users/anh . Substitute your login id for your machine.The slashes separate nested directories. The top hard drivedirectory is / , which contains the directory Users which containsusers’ home directories, like my anh . A shorthand in a terminal for your home directoryis ~ .
The terminal shows a system prompt when it is ready for user input. The promptcan be set to show many things. The end of the prompt is often
$ .Before that is often some indication of your current directory, like ~ forthe home directory.
If you want to see the full name of the current directory enter the command
Single commands are executed after you press the Enter key.
You can list the contents of a directory with the
ls command.Unix tends to abbreviate words in commands.
If you use the ls command in your home directory, you should see
Desktop , Documents , Downloads , . listed.
To change directory, use the
cd command followed bythe directory you would like to change to. You can use the fullname of the directory starting with / , but more commonly you just indicatewhere to go relative to where you are now. Desktop is a subdirectory ofyour home directory, so from the home directory you can just enter
cd Desktop
Here is a sequence on my computer after starting a terminal (skipping mostof the output from
ls )

anh@lucky13:~$ ls

Documents .
.
anh@lucky13:~$ cd Desktop
/Users/anh/Desktop
anh@lucky13:~$ pwd
anh@lucky13:~$
Notice that the last use of the
cd command used directory . .That stands for the parent directory, the directory containing thecurrent directory.

Mac Install Python 3.6
It is useful to be in the examples folder. If you start Idle from there,it is easy to open any of the example programs.
When scripts are directly called by the operating system, they lookfor the proper interpreter to read them. Our scripts are set up to look forpython3.
To start a regular python program from the current directory, like hello_you.py,you would enter a command with python3 and the file name, like

python3 hello_you.py

Instead of shifting to a separate Shell as in Idle, the output appears right in theterminal window.
