QuantConnect supports coding in Python and C#, but also supports other languages through its open-source project, the Lean Algorithmic Trading Engine (LEAN). [8] [9] [10] LEAN is an open-source algorithmic trading engine that allows users to do the same algorithm design, backtesting, and trading that they can do on the website. Once users code ...
Lean was launched by Leonardo de Moura at Microsoft Research in 2013. [3] The initial versions of the language, later known as Lean 1 and 2, were experimental and contained features such as support for homotopy type theory – based foundations that were later dropped. Lean 3 (first released Jan 20, 2017) was the first moderately stable version ...
Cython provides optional manual memory management by letting the user import malloc, realloc, and free from C, which they can then use in Python code. [ 19 ] D provides programmers with full control over its own garbage collector, including the ability to disable it outright.
In computer science and logic, a dependent type is a type whose definition depends on a value. It is an overlapping feature of type theory and type systems.In intuitionistic type theory, dependent types are used to encode logic's quantifiers like "for all" and "there exists".
Lean thinking, a business methodology adopted in various fields; Lean construction, an adaptation of lean manufacturing principles to the design and construction process; Lean government, application of lean thinking to government; Lean higher education, application of lean manufacturing principles in Higher Education
scikit-learn (formerly scikits.learn and also known as sklearn) is a free and open-source machine learning library for the Python programming language. [3] It features various classification, regression and clustering algorithms including support-vector machines, random forests, gradient boosting, k-means and DBSCAN, and is designed to interoperate with the Python numerical and scientific ...
Lean thinking has to be understood well by all members of a project, before implementing in a concrete, real-life situation. "Think big, act small, fail fast; learn rapidly" [ 8 ] – these slogans summarize the importance of understanding the field and the suitability of implementing lean principles along the whole software development process.
The Zen of Python is a collection of 19 "guiding principles" for writing computer programs that influence the design of the Python programming language. [1] Python code that aligns with these principles is often referred to as "Pythonic". [2] Software engineer Tim Peters wrote this set of principles and posted it on the Python mailing list in ...
