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.
- Python | Check order of character in string using OrderedDict( )
- Python program for removing i-th character from a string
- Python program to find occurrence to each character in given string
- Python Regex | Program to accept string ending with alphanumeric character
- Python program to check if a given string is Keyword or not
- Python program to check if given string is pangram
- Python program to check if a string is palindrome or not
- Python program to check if string is empty or not
- Python program to check if a string contains all unique characters
- Python program to check if given string is vowel Palindrome
- Python | Lowercase first character of String
- Python | Frequency of each character in String
- Count occurrences of a sub-string with one variable character
- Python | Count occurrences of a character in string
- Python | Split string on Kth Occurrence of Character
