正则表达式(称为RE,或正则,或正则表达式模式)本质上是嵌入在Python中的一种微小的、高度专业化的编程语言,可通过re模块获得。 使用这种小语言,你可以为要匹配的可能字符串集指定规则;此集可能包含英语句子,电子邮件地址,TeX命令或你喜欢的任何内容。 然后,您可以询问诸如“此字符串是否与模式匹配?”或“此字符串中...

Let's try one more example. This RegEx [0-9]{2, 4} matches at least 2 digits but not more than 4 digitsExpressionStringMatched? [0-9]{2,4} ab123csde 1 match (match at ab123csde) 12 and 345673 3 matches (12, 3456, 73) 1 and 2 No match| - Alternation...
Example: For a regex [0-9]+, the input I saw 279 ants and 1 elephant will return Field(4) because it contains 4 numbers. Whereas an input like Cheese will return Field(0) because there are no digits in the input, which can also invalidate the input like Bool(false). For a defined...
Unicode mode with flag u adds strict errors (for unreserved letter escapes, octal escapes, escaped literal digits, quantified lookahead, and unescaped special characters in some contexts), switches to code-point-based matching (changing the potential handling of the dot, negated sets like \W, cha...
