What is Python?
Python is a high-level, multi-paradigm programming language that focuses on interoperability with other programming languages and extensibility. Python fully supports object-oriented programming, structural programming, and an array of other paradigms. It is designed to be extensible through modules, with functionality enhancements through programmable interfaces to existing applications.
Essentially, Python is a lean and compact core language, with a substantial standardized library. Unlike the C family of languages, for example, Python is known for its simple syntactical and grammatical constructs and its tolerance for a range of coding styles. As a powerful, but user-friendly language, Python has achieved prominence with new programmers and experts alike.
Python and Data Science
Data science is an interdisciplinary field that relies on statistical and computational methods to glean information from various data types. It involves data mining, or the use of statistical techniques and analytical processes for examining and manipulating data. Machine learning and simulation are often used as well to augment data evaluation and interpretation efforts.
Examples of data science-driven activities include predictive analytics, which focuses on analyzing patterns in data, seeking trends, and extrapolating on possible future scenarios based on past behavior. Visualization is often used in conjunction with predictive analytics, providing graphic representations that help researchers see and interpret patterns that emerge from the data.
Across many professional fields, including quantitative finance, Python has become popular due to its extensive libraries, versatility, and ease of use. It offers an efficient, intuitive solution for handing complex data structures and generating insights. Python is frequently employed in artificial intelligence and machine learning research, making use of libraries like Pytorch, TensorFlow, Keras, and scikit-learn. Because Python has a modular architecture, simple syntax, and rich text processing tools, it is also well-suited for natural language processing.
In specialized scientific computing projects, such as applications in quantitative finance, Python makes use of libraries like SciPy, NumPy, and Matplotlib to provide domain-specific functionality. Some of the most common models in quantitative finance rely on linear algebra, stochastic calculus, partial differential equations, numerical methods, and complex algorithms, all of which can be handled in Python. In addition, it can be used in computer simulation, including Monte Carlo methods, and supports data analytics and machine learning techniques as applied to traditional and alternative data sets.
For those interested in learning more about Python and data science, there are many options from videos and short online courses to university degree programs. While the free courses are a good beginning for some learners, they tend to lack the rigor and formal structure needed to advance further. University programs add rigor and formalism to the studies but tend to be expensive and difficult to undertake alongside full-time employment. One solution for quant professionals who want to boost their programming skills in Python and apply those skills professionally is the Certificate in Quantitative Finance.
