About this course.

Python is the working language of data teams from London to Singapore. This course takes you from a clean installation to confident, reproducible analysis with pandas, the library behind most analyst and data scientist job descriptions.

You will learn the core language first, then load, clean, join and summarise real-world tables, chart the results and package your work so a colleague can rerun it. Every module ends with a short quiz, and the final assessment confirms the skills employers ask for.

Who this is for

  • Analysts moving from Excel to code
  • Graduates preparing for data analyst or junior data scientist roles
  • Engineers and finance professionals who need to automate reporting
  • Anyone applying for a role that lists Python, pandas or Git as a mandatory skill

Skills this certificate proves: Python (Proficient), Pandas (Proficient), Git (Working).
