Given a string, the task is to check if that string contains any special character (defined special character set). If any special character found, don’t accept that string.
Input : Geeks$For$Geeks Output : String is not accepted. Input : Geeks For Geeks Output : String is accepted
Approach : Make a regular expression(regex) object of all the special characters that we don’t want, then pass a string in search method. If any one character of string is matching with regex object then search method returns a match object otherwise return None.
Below is the implementation :
String is not accepted.
