    import Foundation

    /* * Define an ErrorType */ enum StringToIntTypecastingError: Error { case BadString }

    func stringToInt(inputString: String) throws -> Int {
    guard let int = Int(inputString) else {
        throw StringToIntTypecastingError.BadString
    }
    return int
}

    /* * Read the input */ let inputString = readLine()!

    do { try print(stringToInt(inputString: inputString)) } catch StringToIntTypecastingError.BadString { print("Bad String") }

    **// I am getting Error reading result file.You should use exception handling concepts.

    but output printing correct can any one please help in this in Swift language **

    public class Solution { public static void main(String[] args) throws IOException { BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));

        String S = bufferedReader.readLine();
    try
    {
        System.out.println(Integer.parseInt(S));
    }
    catch(Exception ex)
    {
        System.out.println("Bad String");
    }
    bufferedReader.close();
}

    }

    For Python3 Remove "if name =='main'; before implementing 

    S = input()
try:
    print(int(S))
except ValueError:
    print("Bad String")

    Python is not checkable i think. Some file read error. Is this code OK?

    if __name__ == '__main__':
    S = input()
    if S.isnumeric():
        print(int(S))
    else:
        print("Bad String")
