Скачать или смотреть Practice Makes Regexp: 50 exercises to improve your fluency with regular expressions

Do you struggle to remember the syntax of regular expressions ("regex" or "regexp")? Do you go to Stack Overflow to find out how to use regexps to solve a problem? If so, then what you need is practice — and lots of it.


In my book, Practice Makes Regexp ( http://store.lerner.co.il/practice-ma... ), you're given 50 exercises to solve using regular expressions. As you progress through the book, you discover how to use not only the basic metacharacters, but also more advanced techniques, including grouping and lookahead/lookbehind. The final chapter's exercises use the "grep" command in the Unix shell.


If you work with text — and every developer does! — then Practice Makes Regexp is what you need to improve your fluency. With solutions in Python, JavaScript, Ruby, and PostgreSQL.
