Turn your Android Smart Phone into a Web Server using python.

I used Pydroid 3 --IDE for Python 3, but I burned my hand and stopped using it!

Install UserLand from Google Play.

Log in with ssh. I'm using Rlogin. It is Port 2022.

The linux screen will appear.

We will improve the environment. Enables the use of vim editor.

sudo apt update
sudo apt upgrade -y
sudo apt install -y vim

vim test.c
#include <stdio.h>
int main(){
        printf("hello world\n");
}

hirata@localhost:~$ cc test.c
hirata@localhost:~$ ./a.out
hello world
hirata@localhost:~$

OK if hello world appears!

Introduction and confirmation of python

sudo apt update
sudo apt install python3
sudo apt install python3-pip

hirata@localhost:~$ python3
