Learning Streamlit with Penguins 🐧

In the Pythonic realm 🐍👑 of data and machine learning web application frameworks Streamlit has been acquiring quite a lot of popularity. In fact, Streamlit is designed to be incredibly user-friendly. You can create interactive web apps with just a few lines of Python code. It abstracts away much of the complexity involved in web development, making it accessible even to those without a web development background.

Environment 🌀 and Installation 👩🏽‍🔧👨🏽‍🔧

Prerequisite

• Python 3.11.3 or above up to 3.11.6 (We will use pyenv for Python Version Management but feel free to use any other tool)
• Virtual environment (We will use the module venv from python but you can use any other tool)

For MacOs/Linux users

# Sets the local Python version to 3.11.3 using pyenv
pyenv local 3.11.3 
# Create a Virtual Environment named .streamlit_env using venv
python -m venv .streamlit_env
# Activate the Virtual Environment
source .streamlit_env/bin/activate
# Install Streamlit and Additional Libraries
pip install -r requirements.txt

For Windows users with PowerShell CLI

# Sets the local Python version to 3.11.3 using pyenv
pyenv local 3.11.3 
# Create a Virtual Environment named .streamlit_env using venv
python -m venv .streamlit_env
# Activate the Virtual Environment
.streamlit_env\Scripts\Activate.ps1
# Install Streamlit and Additional Libraries
pip install -r requirements.txt

For Windows users with GIT-BASH CLI

# Sets the local Python version to 3.11.3 using pyenv
pyenv local 3.11.3 
# Create a Virtual Environment named .streamlit_env using venv
python -m venv .streamlit_env
# Activate the Virtual Environment
source .streamlit_venv/Scripts/activate
# Install Streamlit and Additional Libraries
pip install -r requirements.txt

🧪 Test Streamlit Installation 👨🏽‍🔧👩🏽‍🔧

You can check if Streamlit is installed correctly and run a sample app with the following command:

streamlit hello

This should open a Streamlit web app in your default web browser.

Further Readings 📚

The following is a list of other popular python web framework:

• Django
• Dash
• Flask
• FastAPI
• Taipy

Both FastAPI and Flask are primarily focused on backend development for web applications.
