Write a regular expression patt that can be used to extract (numerator,denominator,operator,numerator,denominator) from a string containing a fraction, an arithmetic operator, and a fraction. You may assume there is a space before and after the arithmetic operator and no spaces surrounding the character in a fraction. And all fractions will have a numerator and denominator. Example: >>s 23/45 14/9" >>>re.findal I (patt,s) >>S"-23/45 1419 >>>re.findal I (patt,s) In general, your code should handle any of the operators +, * and I. -, Note: the operator module for the two argument function equivalents of the arithmetic (and other) operators Write a regular expression patt that can be used to extract (numerator,denominator,operator,numerator,denominator) from a string containing a fraction, an arithmetic operator, and a fraction.
