Practical Application Cases

1. Education and Training

Pydroid 3 has a wide range of applications in the fields of education and training. Many educational institutions use Pydroid 3 to teach Python programming courses and help students practice and test code on mobile devices.

2. Data Science Projects

Some data scientists use Pydroid 3 for data analysis and modeling on mobile devices. This allows them to process and analyze data anywhere and improve work efficiency.

3. Mobile Application Development

Some developers use Pydroid 3 for rapid prototyping and development of mobile applications. With Pydroid 3, they can write and test code on mobile devices to quickly verify and demonstrate their ideas.

Run Python code

1. Edit Python code

Take the output of hello world as an example:

2. Click the folder icon in the upper right corner to save, or click the run icon in the lower right corner to run without saving.

Running result:

Run C language code:

1. Edit a section of C language code:

Take the output of hello world as an example:

2. Run C language code:

    1. First, click the folder icon in the upper right corner to save the code file (save it to a location that can be found), with the suffix ".c"

    2. Click the menu in the upper left corner and click Terminal to enter the terminal (linux)

    3. Use the cd command to enter the folder where the code file was just saved (the ls command can view the files in the current folder)

    4. Use gcc to compile the c code. If there is no error, the compilation is successful

    5. Run the a.out file in the current folder

Quick Guide:

Pydroid 3 necessitates a minimum of 250MB of free internal memory, with 300MB or more being recommended, especially when utilizing heavy libraries such as scipy. To debug, place breakpoints by clicking on the line numbers. Kivy, PySide6, sdl2, tkinter, and pygame can be activated through specific mode declarations. A dedicated mode "#Pydroid run terminal" ensures the program operates in terminal mode, beneficial for applications like matplotlib that default to GUI mode.

Explanation Regarding Premium-Only Libraries:

Certain libraries are exclusively available to Premium users due to the significant complexity involved in their porting process, necessitating collaborations with alternative developers. If users wish to create free versions of these premium libraries, they are encouraged to contact the Pydroid 3 team.

Engage in Pydroid 3 Development:

Users are encouraged to participate in Pydroid 3's development by reporting bugs or suggesting new features. The primary focus remains on porting scientific libraries to aid in Python 3 programming education, with system-related libraries integrated solely when essential for other educational packages.
