In lesson 11 - RegEx B - Python for Everybody Course.
The following regex is used: '\S+@\S+', but in the exercise the regex is different: '\\S+@\\S+' . Two extra backslash characters are used, but the outcome is the same. I don’t understand why the extra \ does not affect the regex (should escape a special character).
