What I've learnt about Python
If you have Python Installed already.
You can do very cool things with it.

Python Apps Reliability
A good readme does the trick for any project.
This is a good Python Project Readme.
Python Virtual Envs
There are several ways to install Python Dependencies.
Python must have pip & venv ready 📌
sudo apt install python3-pip
sudo apt install python3.10-venvMake the dependencies Work: Venv’s in Python 📌
As per Docs
#python -m venv solvingerror_venv #create the venv
python3 -m venv solvingerror_venv #create the venv
#solvingerror_venv\Scripts\activate #activate venv (windows)
source solvingerror_venv/bin/activate #(linux)Install dependencies with:
#pip install beautifulsoup4 openpyxl pandas numpy==2.0.0
pip install -r requirements.txt #all at once
#pip freeze | grep langchain
#pip show beautifulsoup4
pip list
#pip freeze > requirements.txt #generate a txt with the ones you have!source .env
#export OPENAI_API_KEY="your-api-key-here"
#set OPENAI_API_KEY=your-api-key-here
#$env:OPENAI_API_KEY="your-api-key-here"
echo $OPENAI_API_KEYContainers for Python Apps
Making sure a Python app will always work is by building & using containers.
Local container build 📌
#docker build -t trip_planner .
DOCKER_BUILDKIT=1 docker build --no-cache --progress=plain -t trip_planner .CI/CD container build 📌
You can use tools like: Jenkins, or Github Actions CI/CD Workflows
Python Notebooks
Executing Python code step by step is great for exploratory purposes.
We can do it with the .ipynb, Python notebooks, executed in Google Colaboratory:
