A regular expression, or regex, is a sequence of characters that defines a search pattern. It is a powerful tool for pattern matching and manipulation of strings. Python provides theremodule, which allows us to work with regular expressions. To use regular expressions in Python, we need to im...
java.util.regex.Pattern 声明一个正则表达式。 java.util.regex.Matcher 提供的各种正则匹配、结果获取方法。 java.lang.String.replaceAll 根据正则表达式匹配并替换。 1. Pattern 创建一个正则对象 Pattern pattern = Pattern.compile("\\{[yMdHhms][yMdHhms -:/\\\]*\\}"); 1...

Why not instead map patterns to letters and do traditional regex-matching? Support ellipsis-like syntax to match anything in the rest of the list or tuple. Matchsetexpression? Add “when” clause like match(expr, when(predicate)) Addor/andpattern-matching ...
To avoid duplication, we could refactor the code body into a method, but case clauses also support an “or” construct, using a | method: // src/main/scala/progscala2/patternmatching/match-variable3.sc for { x <- Seq(1, 2, 2.7, "one", "two", 'four) } { val str = x match...
