PeterJohn V4 PlayGrounds

****What is this;;
PeterJohn is a Python3 PlayGrounds runs on iPhone.
This enables you to code, run and learn Python3 even on the train, on the bus, even Offline.

****Why we named "PeterJohn";;
Peter is the son of Old John. Young John is the son of Zebedee.
Peter and Young John led Christianity in the early church.
We named "PeterJohn" after the two names of Peter and Young John.

** Why we made this and Why we chose Python3;;
We wanted to code even on the train or even on the bus,
even on OffLine.
and wanted to offer you to do the same things.
We chose Python3 as the programing language.
'cause the Curly Bracket language such
as JavaScript needs many lines and
it's Not appropriate in the narrow iPhone screen.

**Basic Technology;;
PeterJohn is constructed on some of basic technologies.

**Python-Apple-Support;;
We didn't want to make any Wheel language and
any Wheel interpreter.
so we chose Python3 and
we used "Python-Apple-Support" as the Python3 interpreter.
"Python-Apple-Support" is one of CPython.

**CPython's Extension Function;;
This is used for Python to call Swift function
such as GUI
via Objective-C and
for Swift to call Python via Objective-C
in order to offer Python3 interpreter.

**PeterJohn-Bridging-Header.h;;
This is used to import Objective-C header files to Swift.
This enables Swift to use CPython's Extension Function via Objective-C.

**PeterJohn-Swift.h;;
This enables CPython's Extension Function to use Swift such as GUI via Objective-C.

**AudioKit;;
To implement playing MIDI function, we used AudioKit.

**squash.py;;
Many people on this planet have learned the programing
from the "squash.py".

****What we offer you;;
**s00stdErrTest.py;;
iOS hides "stderr" to make simple to use iPhone.
but it's required when we learn Python3.
so I wrote "logStdErr.py".
Import "logStdErr" and
execute "logStdErr.errToFile()"
in your code.

**s01basicUi.py;;
pj.title()
pj.removeAllFromCanvas()
pj.createRectangle()
pj.createCircle()
pj.createLabel()
pj.setText()
pj.updateMainPanel()

**s02midiTest.py;;
pj.midi();

**s03bindTest.py;;
pj.bindMotionFunction()
pj.bindMotionCanvasFunction()
pj.bindButtonFunction()
pj.bindKeyPressFunction()
For example,
pj.bindButtonFunction("p1:s03bindTest.click")
By the notation of "p1:s03bindTest.click",
the function "click" is executed
only from the script file "s03bindTest" in the project "p1".

**s04timerTest.py;;
pj.startTimerFunctionAfter()
pj.stopTimer()
For example,
pj.startTimerFunctionAfter("p1:s04timerTest.gameLoop")
By the notation of "p1:s04timerTest.gameLoop",
the function "gameLoop" is executed
only from the script file "s04timerTest" in the project "p1".

**s05squash.py;;
This is the "PeterJohn" implementation
of the Famous "squash.py".

**s06spriteBundle.py;;
pj.createSpriteBundle()
This's just a demonstration,
you need to proceed to create Sprite from SandBox
'cause the Bundle file is freezed when we submitted
this app to AppStore and
you can Not change the Bundle file.

**s07audioBundle.py;;
pj.playSoundEffectsBundle()
pj.prepareBgmBundle()
pj.playBGM()
This's just a demonstration,
you need to proceed to create Audio from SandBox
'cause the Bundle file is freezed when we submitted
this app to AppStore and
you can Not change the Bundle file.

**s08spriteSandBox.py;;
pj.createSpriteSandBox()
You can import your PNG files to your project.

**s09audioSandBox.py;;
pj.playSoundEffectsSandBox()
pj.prepareBgmSandBox()
pj.playBGM()
You can import your MP3 files to your project.

**Acknowledgements;;
Thank you Lord, Thank you King Jesus.

Thank you AppStore Review Team, every day.

"in LandScape mode, inputResultLabel, Position of Cursor BugFixed" and "Stoped PyFinalizeEx(()" Version;
(1) In LandScape mode, at the InputLabel, position of Cursor was Wrong, we Fixed the Bug at this time.
(2)we Stopped PyFinalizeEx() 'cause PyFinalizeEx() doesNot Work Well, for example, in some of situations,
some of Apps which use Thread in the LandScape mode will CRASH when it executes PyFinalizeEx().

****Ezekiel 34:3-6, GNT;
34:3 You drink the milk, wear clothes made from the wool, and kill and eat the finest sheep. But you never tend the sheep. 
34:4 You have not taken care of the weak ones, healed the ones that are sick, bandaged the ones that are hurt, brought back the ones that wandered off, or looked for the ones that were lost. Instead, you treated them cruelly. 
34:5 Because the sheep had no shepherd, they were scattered, and wild animals killed and ate them. 
34:6 So my sheep wandered over the high hills and the mountains. 
They were scattered over the face of the earth, and no one looked for them or tried to find them.

Even if you live in the evil country which Evil Emperor rules, You MustNot Lose the Hope that King Jesus comes.
