Python for Data Science: Python and Data Science

By Desmond Onam

Does any of this sound familiar?You've watched hours of YouTube tutorials but still can't write a script from scratch without copying someone else's code.You open a dataset and freeze - you know pandas exists, but you don't know where to even start cleaning messy real-world data.You understand the theory but your portfolio is empty. Interviewers want projects, not certificates.You've tried three different courses, all jumping straight into machine learning before you've mastered the fundamentals - leaving you more confused than when you started.You're an analyst who's comfortable in Excel but feel left behind as your team moves to Python - and you're embarrassed to ask the basics.

This eBook was written to fix exactly that.

Most data science resources fall into two traps: they either spend 10 hours on Python basics before touching any data, or they skip the fundamentals entirely and assume you already know how everything works. This book does neither. Every chapter is built around a practical goal - cleaning a dataset, computing a statistic, drawing a chart - so you are always learning in context, never in the abstract.
Who is this for?
Complete beginners
No prior coding experience needed. We start from zero - installing Python, understanding variables - and build systematically.
Excel analysts
Already comfortable in spreadsheets? This book is your bridge to Python - mapping Excel concepts to pandas so nothing feels foreign.
Developers switching to data
You know how to code. This skips the programming theory and focuses purely on the data science stack and its idioms.
Career changers
Want to break into data science or analytics? The two capstone projects give you real portfolio pieces to show interviewers.
