Every data science workflow starts with code. This course builds practical programming fluency in both Python and R, covering data structures, wrangling, and visualization so participants can move confidently between the two most widely used data science languages.
Python and R remain the two dominant languages in data science, each with strengths analysts need to draw on. This course builds working programming fluency in both — covering core syntax, data structures, control flow, and the libraries used daily for data wrangling and visualization.
Participants complete parallel exercises in Python and R, building the comparative fluency needed to choose the right tool for a given data science task and collaborate across teams that use either language.
Throughout the programme, participants work through realistic scenarios drawn from technology organizations, digital transformation programmes, data-driven enterprises, and public sector IT environments, examining how programming for data science (python & R) is applied in practice and where it most often breaks down. Delegates will develop practical skill in designing appropriate frameworks, selecting and applying the right tools for core data structures in r, interpreting findings, and communicating conclusions clearly to colleagues, management and external stakeholders. Sessions move deliberately from principles to application, so that each technique introduced is practised against a realistic problem before the programme moves on — strengthening both individual effectiveness and the wider capability of the organizations delegates return to.
By the end of this course, participants will be able to:

This training course adopts a practical, participant-centered learning approach that builds programming for data science (python & R) expertise, strengthens analytical capability and develops confident professional judgement. The methodology combines specialist facilitation, applied hands-on experience and globally recognized professional practice, so that delegates return able to apply what they have learned immediately rather than in theory only.
Methodology includes:
Day 1: Setting Up and Writing Your First Code in Python and R
Day 2: Core Data Structures in Python
Day 3: Core Data Structures in R
Day 4: Control Flow, Functions and Reusable Code
Day 5: Data Wrangling with pandas
Day 6: Data Wrangling with dplyr and tidyr
Day 7: Importing and Exporting Data
Day 8: Visualization with matplotlib, seaborn and ggplot2
Day 9: Debugging, Testing and Reliable Data Workflows
Day 10: Choosing the Right Tool and Building an End-to-End Project
Programming for Data Science (Python & R) Training suits people who handle data daily but write little or no code, and those fluent in one language who need working competence in the other.
Delegates who complete all ten days receive a Certificate of Completion from Vision Reach Global Consultancy, confirming their ability to write and debug Python and R code for data manipulation, apply pandas and dplyr to clean and transform datasets, and produce visualisations with matplotlib, seaborn and ggplot2.
Everything you need to know about this course before you register.
By the end of the Programming for Data Science (Python & R) Training programme, you'll be able to write functional python and r code for data manipulation tasks, use pandas and dplyr to clean, filter, and transform datasets, apply core programming concepts: loops, functions, and conditionals, and visualize data using matplotlib, seaborn, and ggplot2. The full breakdown of topics is covered session by session in the Course Outline tab above.
Programming for Data Science (Python & R) Training suits people who handle data daily but write little or no code, and those fluent in one language who need working competence in the other. Typical delegates include Data Analysts and Reporting Analysts moving from spreadsheets to scripted workflows, Junior Data Scientists consolidating Python and R fundamentals, Business Intelligence Developers extending SQL skills into pandas and dplyr, Statisticians and Research Analysts adopting reproducible scripting, Database and Data Engineers who need scripted import, export and transformation routines, Actuarial, Finance and Marketing Analysts building their own data pipelines, and Academic Researchers and Postgraduate Students preparing data for analysis and publication.
