Python for Data Analysts & Quants
Use Python and its statistical computing libraries to analyse and visualise your data and to gather some actionable insights.
Our Python for Data Analysts and Quants training course covers an introduction to the core concepts of the Python language and data science, ultimately focusing on big data analytics including how best to manipulate and visualise your data with Python's excellent library support.
This intensive course is intended for Data Scientists, Quants, Data Analysts and Business Intelligence experts who want to understand how to use Python in their data-oriented environment.
Practical exercises and interactive walk-throughs are used throughout, so attendees have the opportunity to apply the concepts on real data science applications, from exploratory data analysis to predictive analytics.
The Python Machine Learning syllabus is designed to help analysts, researchers, BI experts and developers becoming familiar with the implementation of Machine Learning solutions, through the use of tools in the Python programming language ecosystem.
Using a mix of frontal presentation and interactive examples, the course provides a comparison between Supervised and Unsupervised Learning, and offers an overview on core algorithms for predictive analytics, tackling tasks such as classification, clustering, regression analysis and dimensionality reduction. Notions of Neural Networks and latest developments in Deep Learning are also discussed.

Course outline:
Installation & Packaging
- Installation, packaging and virtualisation of Python using Conda.
- We'll set up Python using the Anaconda distribution, a free and enterprise-ready Python distribution that includes hundreds of the most popular Python packages for science, math, engineering and data analysis.
- Anaconda comes with Conda, a cross-platform tool for managing packages and virtual environments. We'll also set up Jupyter, a web-based interactive environment where users can organise, write and run their Python code in notebooks.
Python Core Concets & Best Practices
- Introduction to Python basic concepts, data structures and control flow structures.
- Overview of how Python is used for Data Science and Data Analytics projects.
- Notions of Object-Oriented Programming and Functional Programming, applied to the design of Python applications and analysis pipelines using best practices.
- Core data types in Python
- Control flow statements
- Defining and using custom functions
- The Python standard library
- Working with data:
- Iteration and list comprehensions
- Accessing raw data on file (CSV, JSON, ...)
- Working with dates and times
- Object-Oriented Programming in Python
Python Data Science Tools
- We'll explore the most important Python tools for Data Science.
- NumPy, short for Numerical Python, is one of the main building blocks for scientific computing in Python.
- It provides high speed manipulation of multi-dimensional arrays and it's used by higher level libraries (like pandas) to support sophisticated analytics with high speed computation.
- Pandas is a highly performant library for data manipulation and data analysis in Python. It's built on top of NumPy and optimised for performance, while offering a high-level interface.
- We'll discuss how to create and manipulate Series and DataFrame objects in pandas, accessing data from multiple sources, cleaning and transforming data sets to get them in the right shape for advanced analysis.
Accessing & Repairing Data
- Data can come in multiple formats and from multiple sources. We'll examine how to read and write data from local files in different formats, and how to access data from remote source.
- Data cleaning and data preparation are the first steps in a data analysis project, so we'll discuss how to perform data transformation to get ready for further analysis.
Data Analysis
- With our data in the right shape, we're ready to analyse them in order to extract useful insights.
- We'll perform the computation of summary information and basic statistics from data sets.
- We'll approach split-apply-combine operations with Data Frames, in order to perform advanced transformations and reshaping our data with pandas.
- We'll query our Data Frames using the powerful group-by method.
Data Visualization
- Data analysis benefits from the visualisation of data. If a picture if worth a thousand words, complex data structures can be easier to understand and analyse using effective visualisation techniques.
- Communicating the results with non-technical users is also a challenge that visualisation techniques help to overcome.
