Regular expressions training course description Regular expressions are an extremely powerful tool for manipulating text and data. They are now standard features in a wide range of languages and popular tools, including Python and MySQL. Regular expressions allow you to code complex and subtle text processing that you never imagined could be automated. Once you've mastered regular expressions, they'll become an invaluable part of your toolkit. You will wonder how you ever got by without them. What will you learn Use Regular Expressions. Troubleshoot Regular Expressions. Compare RE features among different versions. Explain how the regular expression engine works. Optimize REs. Match what you want, not what you don't want. Regular expressions training course details Who will benefit: Anyone looking to use regular expressions. Prerequisites: None. Duration 1 day Regular expressions training course contents Introduction to Regular Expressions Solving real problems, REs as a language, the filename analogy, language analogy, RE frame of mind, searching text files: egrep, egrep metacharacters, start and end of the line, character classes, matching any character with dot, alternation, ignoring differences in capitalization, word boundaries, optional items, other quantifiers: repetition, parentheses and backreferences, the great escape, expanding the foundation, linguistic diversification, the goal of a RE, more examples, RE nomenclature, Improving on the status quo. Extended introductory examples A short introduction to Perl, matching text with regular expressions, toward a more real-world example, side effects of a successful match, Intertwined regular expression, intermission, modifying text with regular expressions, example: form letter, example: prettifying a stock price, automated editing, a small mail utility, adding commas to a number with lookaround, text-to-HTML conversion, that doubled-word thing. Regular expression features and flavours The regex landscape, origins of REs, care and handling of REs, Integrated handling, procedural and object-oriented handling, search-and-replace example. strings character encodings and modes, strings as REs, character-encoding issues, unicode, regex modes and match modes, common metacharacters and features, character representations, character classes and class-like constructs, anchors and other 'zero-width assertions', comments and mode modifiers, grouping capturing conditionals and control. The mechanics of expression processing Two kinds of engines, new standards, regex engine types, from the department of redundancy department, testing the engine type, match basics, about the examples, rule 1: the match that begins earliest wins, engine pieces and parts, rule 2: the standard quantifiers are greedy, regex-directed versus text-directed, NFA engine: regex-directed, DFA engine: text-directed, first thoughts: NFA and DFA in comparison, backtracking, two important points on backtracking, saved states, backtracking and greediness, more about greediness and backtracking, problems of greediness, multi-character 'quotes', lazy quantifiers, greediness and laziness, laziness and backtracking, possessive quantifiers and atomic grouping, possessive quantifiers ?, +, *+, ++ and {m,n}+, the backtracking of lookaround, is alternation greedy? taking advantage of ordered alternation, NFA DFA and posix, the longest-leftmost', posix and the longest-leftmost rule, speed and efficiency. Practical regex techniques Continuation lines, matching an IP address, working with filenames, matching balanced sets of parentheses, watching out for unwanted matches, matching delimited text, knowing your data and making assumptions, stripping leading and trailing whitespace, matching and HTML tag, matching an HTML link, examining an HTTP URL, validating a hostname, plucking a hostname, plucking a URL, parsing CSV files. Crafting an efficient expression Efficiency vs. correctness, localizing greediness, global view of backtracking, more work for POSIX NFA, work required during a non-match, being more specific, alternation can be expensive, benchmarking, know what you re measuring, benchmarking with Python, common optimisations, the mechanics of regex application, pre-application optimizations, optimizations with the transmission, optimization of the regex itself, techniques for faster expressions, common sense techniques, expose literal text, expose anchors, lazy versus greedy: be specific, split into multiple REs, mimic initial-character discrimination, use atomic grouping and possessive quantifiers, lead the engine to a match, unrolling the loop, observations, using atomic grouping and possessive quantifiers, short unrolling examples, unrolling C comments, the free flowing regex, a helping hand to guide the match, a well-guided regex is a fast regex.
The journey through higher education often presents challenges that lead students to seek pay someone to do my assignment solutions whether grappling with complex concepts, language barriers, or time management pressures. These moments typically reflect deeper needs for academic skill development rather than simply a desire for completed work. Our approach transforms these challenges into opportunities for growth through targeted skill building and personalized guidance. Specializing in UK academic standards, we provide structured support that helps students develop essential competencies in research methodology, critical analysis, and scholarly writing the very skills that make pay someone to do my assignment requests unnecessary. This focus on sustainable learning empowers students to meet British academic expectations with confidence and integrity.
Our CITB Online - Site Supervisors’ Safety Training Scheme (SSSTS) Refresher course is designed to give attendees a broad reminder of their responsibilities for health and safety on construction sites. Approved and endorsed by the United Kingdom Contractors Group, the SSSTS refresher course is a must for anyone who occupies a supervisory role on UKCG sites and wants to brush up on their knowledge of their legal responsibilities and the latest construction industry regulations. The SSSTS Refresher course has been created to provide existing supervisors, or those who are just entering into a supervisory role, with in-depth knowledge of health and safety legislation and procedures. If a candidate completed a full SSSTS training course up to 5 years ago, they will be required to attend a refresher programme. Prerequisites SSSTS certificates are of course valid for up to 5 years, but due to the ever-changing nature of the industry, it is recommended that staff stay up to date by enrolling on a refresher course long before the qualification expires. Instructions Please note all Site Supervisor Training courses with the venue “Remote Learning” will be delivered by a tutor over a video call. This training will be delivered and assessed in English language; therefore, a good standard is required to complete the course. Further attendee information will be sent in a separate email, please check your inbox.
