One-time purchase, no subscription. Built by a developer for developers. Maintained since 2015.

Now PeterJohn, a Python Interpreter which Runs on iPhone,   Acquired Two Major Modules, NumPy and Matplotlib. they will help you to study  DataScience, DeepLearning, ReinforcementLearning. it's like King Jesus sent twelve disciples out two by two. **Mark 6:7;12-13, GNT 6:7 He called the twelve disciples together and sent them out two by two. He gave them authority over the evil spirits. 6:12 So they went out and preached that people should turn away from their sins.  6:13 They drove out many demons, and rubbed olive oil on many sick people and healed them. **** How to Use it; 1) First, Touch "Add Tutorial" at the BottomLeft of ProjectsView. 2) Touch "TutorialSeason006" at ProjectsView. 3) Choose One of Four at ScriptsView. s001PILimageFontTest.py; This doesNot use Matplotlib but uses only Matplotlib TTF(TrueTypeFonts). s002matplotlibPltPlot.py s003matplotlibPltLegend.py s004BarChartOnPolarAxis.py 4) Touch "RunScript" at the TopRight of EditScriptView. 5) Only for the first time, the warning that "AppleMetal Cache Directory doesNot Exist" appears, Once needs to go back to EditScriptView, and then touch "RunScript" at the TopRight of EditScriptView Again. 6) the script is Executed at RunScriptView. **** Enjoy NumPy, Enjoy Matplotlib Enjoy DataScience, DeepLearing, ReinforcementLearing.
