Introduction to Data Science with Python
Kickstart your career in the 'new oil' of the 21st century. This course introduces you to the Data Science pipeline using Python, focusing on essential libraries like NumPy and Pandas for data manipulation. In Zambia, as organizations strive to meet the 8th National Development Plan goals, the ability to turn raw information into actionable insights is becoming a critical skill. You will learn how to clean messy datasets and perform basic exploratory data analysis (EDA). If you find the transition from basic coding to data science libraries challenging, 25schools provides specialized study notes and Python practice exercises to help you build a strong foundation for your first-year exams.
