Eliminación de puntuaciones de una string dada

Dada una string, elimine la puntuación de la string si el carácter dado es un carácter de puntuación, según la clasificación de la configuración regional actual de C. La configuración regional predeterminada de C clasifica estos caracteres como puntuación: 

! " # $ % & ' ( ) * + , - . / : ; ? @ [ \ ] ^ _ ` { | } ~ 

Ejemplos: 

// CPP program to remove punctuation from a given string
 
#include <iostream>
using namespace std;
 
int main()
{
    // input string
    std::string str = "Welcome???@@##$ to#$% Geeks%$^for$%^&Geeks";
 
    for (int i = 0, len = str.size(); i < len; i++)
    {
        // check whether parsing character is punctuation or not
        if (ispunct(str[i]))
        {
            str.erase(i--, 1);
            len = str.size();
        }
    }
     
    // print string without punctuation
    std::cout << str;
    return 0;
}

// Java program to remove punctuation from a given string
 
public class Test
{
    public static void main(String[] args)
    {
        // input string
        String str = "Welcome???@@##$ to#$% Geeks%$^for$%^&Geeks";
         
        // similar to Matcher.replaceAll
        str = str.replaceAll("\\p{Punct}","");
         
        System.out.println(str);
    }
     
}

# Python program to remove punctuation from a given string
# Function to remove punctuation
def Punctuation(string):
 
    # punctuation marks
    punctuations = '''!()-[]{};:'"\,<>./?@#$%^&*_~'''
 
    # traverse the given string and if any punctuation
    # marks occur replace it with null
    for x in string.lower():
        if x in punctuations:
            string = string.replace(x, "")
 
    # Print string without punctuation
    print(string)
 
# Driver program
