Great question! Most data science courses cover tools like Python and R for programming, including libraries such as Pandas, NumPy, and Scikit-learn for data analysis and machine learning. You'll also learn SQL for database management and tools like Tableau, Matplotlib, or Seaborn for data visualization. Many programs include Jupyter Notebooks for interactive coding and Git for version control. Some advanced courses even introduce big data platforms like Hadoop or Spark and cloud tools like AWS or Google Cloud to round out your skills. Always check the curriculum to ensure it aligns with your career goals!
