Python One-liners

Python programmers will improve their computer science skills with these useful one-liners. Python One-Liners will teach you how to read and write one-liners: concise statements of useful functionality packed into a single line of code. You`ll learn how to systematically unpack and understand any line of Python code, and write eloquent, powerfully compressed Python like an expert. The book`s five chapters cover tips and tricks, regular expressions, machine learning, core data science topics, and useful algorithms. Detailed explanations of one-liners introduce key computer science concepts and boost your coding and analytical skills. You`ll learn about advanced Python features such as list comprehension, slicing, lambda functions, regular expressions, map and reduce functions, and slice assignments. You`ll also learn how to: - Leverage data structures to solve real-world problems, like using Boolean indexing to find cities with above-average pollution - Use NumPy basics such as array, shape, axis, type, broadcasting, advanced indexing, slicing, sorting, searching, aggregating, and statistics - Calculate basic statistics of multidimensional data arrays and the K-Means algorithms for unsupervised learning - Create more advanced regular expressions using grouping and named groups, negative lookaheads, escaped characters, whitespaces, character sets (and negative characters sets), and greedy/nongreedy operators - Understand a wide range of computer science topics, including anagrams, palindromes, supersets, permutations, factorials, prime numbers, Fibonacci numbers, obfuscation, searching, and algorithmic sorting By the end of the book, you`ll know how to write Python at its most refined, and create concise, beautiful pieces of Python art in merely a single line.
