उदाहरणं: copy करा आणि चालवा
हा code / output:
mkdir -p blinkit_mh_lab/{data/raw,data/clean,notebooks,outputs}
cd blinkit_mh_lab
printf '%s\n' '# Blinkit MH lab (fictional sample data)' > README.md
printf '%s\n' '.ipynb_checkpoints/' '.venv/' 'venv/' '.env' 'data/raw/*.csv' '!data/raw/sample_orders.csv' > .gitignore
printf '%s\n' 'order_id,city,amount_inr' 'BLK-1,Pune,189' 'BLK-2,Nashik,95' > data/raw/sample_orders.csv
printf '%s\n' '{"cells":[],"metadata":{},"nbformat":4,"nbformat_minor":5}' > notebooks/01_clean.ipynb
git init
git add README.md .gitignore data/raw/sample_orders.csv notebooks/01_clean.ipynb
git commit -m "Initial lab skeleton with sample orders"
