Getting Started

Setup Virtual Environment

1. Create a virtual environment:

python -m venv venv

2. Activate the virtual environment:

• On macOS/Linux:

source venv/bin/activate

• On Windows:

.\venv\Scripts\activate

3. Install dependencies:

pip install -r requirements.txt

Running Examples

Navigate to specific topic directories and run the Python scripts. For example:

# Run data format examples
python data_formats_and_storage/format_examples.py

# Run format conversion examples
python data_formats_and_storage/format_conversions.py

1. Clone the repository:

   git clone https://github.com/Murtaza-arif/all-you-need-to-know-for-data-engineer.git

2. Navigate to the project folder:

   cd data-engineering-repo

3. Follow the instructions in each topic folder's README.md file to explore examples and projects.
