This is because the regular expression engine uses \ character for its own escaping purpose.īefore starting with the Python regex module let’s see how to actually write regex using metacharacters or special sequences. The raw string is slightly different from a regular string, it won’t interpret the \ character as an escape character. Note: Here r character (r’portal’) stands for raw, not regex. The above code gives the starting index and the ending index of the string portal.
