Snippet in playgrounds functional?

164

I found some useful snippets in "playground", however, some of them make me a bit confused, such as "stringToBool" and "stringToString" in Python3

the definitions are:
stringToString : Parses string to quoted string
stringToBool : Converts string to bool

Are the original codes doing what they are supported to do?

The original codes in Python3 are as follows:

def stringToBool(input):
    return json.dumps(input)

def stringToString(input):
    import json
    return json.loads(input)

additionally, here are the C++ codes, which make sense

bool stringToBool(string input) {
    transform(input.begin(), input.end(), input.begin(), ::tolower);
    return input == "true";
}

string stringToString(string input) {
    assert(input.length() >= 2);
    string result;

    for (int i = 1; i < input.length() -1; i++) {
        char currentChar = input[i];
        if (input[i] == '\\') {
            char nextChar = input[i+1];
            switch (nextChar) {
                case '\"': result.push_back('\"'); break;
                case '/' : result.push_back('/'); break;
                case '\\': result.push_back('\\'); break;
                case 'b' : result.push_back('\b'); break;
                case 'f' : result.push_back('\f'); break;
                case 'r' : result.push_back('\r'); break;
                case 'n' : result.push_back('\n'); break;
                case 't' : result.push_back('\t'); break;
                default: break;
            }
            i++;
        } else {
          result.push_back(currentChar);
        }
    }
    return result;
}
