Program to check if a string contains any special character
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.
Method: To check if a special character is present in a given string or not, firstly group all special characters as one set. Then using for loop and if statements check for special characters. If any special character is found then increment the value of c. Finally, check if the c value is greater than zero then print string is not accepted otherwise print string is accepted.
