Livros de Ken Youens-Clark
For several consecutive years, Rust has been voted "most loved programming language" in Stack Overflow's annual developer survey. This open source systems programming language is now used for everything from game engines and operating systems to browser components and virtual reality simulation engines. But Rust is also an incredibly complex language with a notoriously difficult learning curve.
Rather than focusing on the language as a whole, this guide teaches Rust using a single small, complete, focused program in each chapter. Author Ken Youens-Clark shows you how to start, write, and test each of these programs to create a finished product. You'll learn how to handle errors in Rust, read and write files, and use regular expressions, Rust types, structs, and more.
Discover how to:
- Use Rust's standard libraries and data types such as numbers, strings, vectors, structs, Options, and Results to create command-line programs
- Write and test Rust programs and functions
- Read and write files, including stdin, stdout, and stderr
- Document and validate command-line arguments
- Write programs that fail gracefully
- Parse raw and delimited text manually, using regular expressions and Rust crates
- Use and control randomness
Life scientists today urgently need training in bioinformatics skills. Too many bioinformatics programs are poorly written and barely maintained--usually by students and researchers who've never learned basic programming skills. This practical guide shows postdoc bioinformatics professionals and students how to exploit the best parts of Python to solve problems in biology while creating documented, tested, reproducible software.
Ken Youens-Clark, author of Tiny Python Projects (Manning), demonstrates not only how to write effective Python code but also how to use tests to write and refactor scientific programs. You'll learn the latest Python features and toolsâ??including linters, formatters, type checkers, and testsâ??to create documented and tested programs. You'll also tackle 14 challenges in Rosalind, a problem-solving platform for learning bioinformatics and programming.
- Create command-line Python programs to document and validate parameters
- Write tests to verify refactor programs and confirm they're correct
- Address bioinformatics ideas using Python data structures and modules such as Biopython
- Create reproducible shortcuts and workflows using makefiles
- Parse essential bioinformatics file formats such as FASTA and FASTQ
- Find patterns of text using regular expressions
- Use higher-order functions in Python like filter(), map(), and reduce()
Learn new programming concepts through 21-bitesize programs
Build an insult generator, a Tic-Tac-Toe AI, a talk-like-a-pirate program, and more
Discover testing techniques that will make you a better programmer

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.
About The Book
The 21 fun-but-powerful activities in Tiny Python Projects teach Python fundamentals through puzzles and games. You’ll be engaged and entertained with every exercise, as you learn about text manipulation, basic algorithms, and lists and dictionaries, and other foundational programming skills. Gain confidence and experience while you create each satisfying project.
Instead of going quickly through a wide range of concepts, this book concentrates on the most useful skills, like text manipulation, data structures, collections, and program logic with projects that include a password creator, a word rhymer, and a Shakespearean insult generator. Author Ken Youens-Clark also teaches you good programming practice, including writing tests for your code as you go.
