If you get this in your Python 3 code test: Compiler Message: Error reading result file.You should use exception handling concepts

then remove this line and test again:

if name == "__main__":

I also stucked in loop to testmy code everywhere, even GPT says my code is correct. I go through discussions and saw same probloem with a guy and tested without that block, I was shocked, my code is now works well and ready for submission.

#!/bin/python3

import math
import os
import random
import re
import sys


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

My JS solution:

const S = readLine();
    
    try {
        Number.isInteger(Number(S)) || (() => { throw new Error(); })();
        console.log(S);
    } catch {
        console.log("Bad String");
    }

string S = Console.ReadLine();

Console.WriteLine(S.Any(c=> !(c >= 48 && c <= 57) || c==' ')?"Bad String":S);

                                             or

Console.WriteLine(Int32.TryParse(S, out int result)?result:"Bad String");

I'm using swift, and getting the same error over and over, did anyone knows how to solve it?

this is meu received error: Compiler Message Error reading result file.You should use exception handling concepts.

and this is my working code:

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

I had to remove the "if name == 'main':"

#!/bin/python3

import math
import os
import random
import re
import sys

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