1. Install nmap [jika belum ada]:
sudo apt install nmap
2. Cek ip address komputer (yg akses ke wifi yang sama):
ip addr
misal hasilnya 192.168.8.25/24 maka basenya adalah 192.168.8.xxx
sehingga kita bisa scan ip lain (di wifi yg sama) dgn base tersebut.
3. scan ip address yg terkonek di wifi address yg sama:
sudo nmap -sn 192.168.8.0/24
Note: sesuaikan dengan ip basenya.

A. Set up virtual environment
1. I assume that you already have python on your computer (linux)
2. Install venv:
sudo apt install -y python3-venv
3. Create virtual environment inside your project directory (example for me: inside data-science folder ):
python3 -m venv venv_01
4. Activate virtual environment:
source venv_01/bin/activate
5. Deactivate virtual environment:
deactivate
B. Set up Sublime:
1. Open Sublime
2. Add new build system on your Sublime:
Tools -> Build System -> New Build System
3. Edit as follow:
{
"cmd": ["/home/<username>/Desktop/data_science/venv_01/bin/python", "$file"],
"file_regex": "^[ ]File \"(...?)\", line ([0-9]*)",
"selector": "source.activate"
}
Replace <username> with your username.
/home/<username>/Desktop/data_science/venv_01 --> this is my virtual environment path (change with your path).
4. Save and give the name (example: python3_venv_01)
C. Test your set up:
1. Try to create simple python code in sublime. For example:
import sys
print(sys.version)
2. Let save as tes.py and save inside your project directory (which is the same folder with your virtual environment).
3. Set Build System
Tools -> Build System -> python3_venv_01
4. To test if the app is working, press CTRL + B
