using the regex(\d+)(?=.*(\1)), I am struggling to match entire lines using^$. My guess is that when I use the lookahead, this is creating an infinite loop where we constantly look at every token (including the repetitions) and expect a repeat later in the string, although...

If you want to match the entire string where you want to match everything but certain strings you can do it like this: ^(?!(red|green|blue)$).*$ This says, start the match from the beginning of the string where it cannot start and end with red, green, or blue and match anything...
>>> m.group(1) # Returns only the last match. 'c3' Match.__getitem__(g) 这个等价于 m.group(g)。这允许更方便的引用一个匹配 >>> 代码语言:javascript 复制 >>> m = re.match(r"(\w+) (\w+)", "Isaac Newton, physicist") >>> m[0] # The entire match 'Isaac Newton' >>...
将正则表达式的样式编译为一个正则表达式对象(正则对象),可以用于匹配,通过这个对象的方法match(),search()以及其他如下描述。 这个表达式的行为可以通过指定标记的值来改变。值可以是以下任意变量,可以通过位的OR操作来结合(|操作符)。 序列 prog=re.compile(pattern)result=prog.match(string) ...
