Pydroid - Python 2 programming app v1.01 [Premium]
Requirements: 4.4+
Overview: Pydroid is the most easy to use and powerful Python 2 IDE for Android.

Features:
- Offline Python 2.7 interpreter: no Internet is required to run Python programs.
- Full-featured Terminal Emulator, with a readline support (available in pip).
- Pip package manager and a custom repository for prebuilt wheel packages for heavy libraries, such as numpy, scipy, matplotlib, scikit-learn and jupyter.
- Examples available out-of-the-box.
- Built-in C, C++ and even Fortran compiler designed by n0n3m4, an author of C4droid, specially for Pydroid. It lets Pydroid build any library from pip, even if it is using native code. You can also build & install dependencies from a command line.
- Cython support.
- PDB debugger with breakpoints and watches.
- Kivy graphical library with a shiny new SDL2 backend.
- PyQt5 support available in Quick Install repository along with matplotlib PyQt5 support with no extra code required.
- Matplotlib Kivy support available in Quick Install repository.
Editor features:
- Code prediction, auto indentation and real time code analysis just like in any real IDE. *
- Extended keyboard bar with all symbols you need to program in Python.
- Syntax highlighting & themes.
- Tabs.
- Enhanced code navigation with interactive assignment/definition gotos.
- One click share on Pastebin.
* Features marked by asterisk are available in Premium version only.
Quick manual.
Pydroid requires at least 170MB free internal memory. 200MB+ is recommended. More if you are using heavy libraries such as scipy.
To run debug place breakpoint(s) clicking on the line number.
SDL2/Kivy is detected with “import kivy”, “from kivy“ or "#Pydroid run sdl2”.
PyQt5 is detected with “import PyQt5”, “from PyQt5“ or "#Pydroid run qt”.
Take a part in development of Pydroid by reporting bugs or providing feature requests to us. We appreciate that.
The list of libraries we are NOT planning to add yet:
- Tensorflow
- OpenCV
- Tk/Tkinter or any libraries having it as a dependency
- Pygame
Important notice:
Some users experienced major problems when installing libraries from QPython QPypi internal repository, so consider it to be binary incompatible with Pydroid. If you need any libraries that cannot be built with Pydroid - contact the devs directly: other binary repositories are likely to be incompatible as well.
Legal information.
Some binaries in Pydroid APK are licensed under (L)GPL, email us for the source code.
GPL pure Python libraries bundled with Pydroid are considered to be coming in the source code form already.
Pydroid doesn’t bundle any GPL-licensed native modules to avoid automatic import of them. The famous example of such library is GNU readline, that can be installed using pip.
What's New
Added an option to disable insertion of quotes/braces

==== Recommended for... ====
[ People in the IT and software industries ]
Whether it be website creation or website management, game development or system development, when using a computer to work as a team or work with clients, a broad knowledge of programming and information security is essential.
With "Algorithms: Explained and Animated", you can firmly strengthen that fundamental knowledge.
[ People interested in programming and information technology ]
While there are many technical books on programming and the internet, their simple drawings and long explanations don't facilitate learning as much as they do boredom. With "Algorithms: Explained and Animated", anything from complex data structures like "hash tables" and "heaps" to information security topics like the "public-key cryptosystem" and "digital certificates" can be easily understood with animations.
[ Experienced programmers and engineers ]
When using standard methods like libraries, the more basic the concept, the more impenetrable it can seem. You might also find yourself struggling to explain concepts to a less-experienced colleague. For times like those, use "Algorithms: Explained and Animated" to keep your skills from getting rusty.
This app is free to download. A portion of the app's topics can be viewed after choosing to "Purchase all algorithms."
