Python and Streamlit on Ubuntu 22.04

Check the installed python

satria@teddy:~$ pip -V
pip 22.0.2 from /usr/lib/python3/dist-packages/pip (python 3.10)

it seems I already installed python 3. but when I want to find out the location with ‘whereis python’, it showed up nothing

satria@teddy:~$ whereis python
python:

so use ‘whereis python3’ instead

satria@teddy:~$ whereis python3
python3: /usr/bin/python3 /usr/lib/python3 /etc/python3 /usr/share/python3 /usr/share/man/man1/python3.1.gz

I need to symlink python 3 to use just ‘python’ like this
satria@teddy:~$ sudo ln -s /usr/bin/python3 /usr/bin/python

then I can use like this
satria@teddy:~$ whereis python
python: /usr/bin/python

Install streamlit with python3 virtual environment (venv)
ref: https://docs.streamlit.io/get-started/installation/command-line

create a new directory.  for  example ‘streamlit’
satria@teddy:~$ cd Documents/projects/python/streamlit/

then go into the dir. make sure you already have python3-venv package. if not install it
satria@teddy:~/Documents/projects/python/streamlit$ sudo apt install python3.10-venv

then use python3-venv like this:
satria@teddy:~/Documents/projects/python/streamlit$ python -m venv .venv

Activate the virtual environment
satria@teddy:~/Documents/projects/python/streamlit$ source .venv/bin/activate
(.venv) satria@teddy:~/Documents/projects/python/streamlit$

install streamlit with pip in the venv
(.venv) satria@teddy:~/Documents/projects/python/streamlit$ pip install streamlit
