    If anyone is trying to solve this problem in Python3. Then use this code not the pre-defined code:

    #!/bin/python3

import math
import os
import random
import re
import sys

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

    For JS this worked:

    function main() {
  const S = readLine();
  try {
    const num = JSON.parse(S);
    console.log(num);
  } catch (e) {
    console.log("Bad String");
  }
}

    But for Python I get: Error reading result file.You should use exception handling concepts.

    I tried this:

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

    and this:

        S = input()
    
    try:
        num=int(S)
        print(num)
    except: 
        raise Exception("Bad String")

    None of these worked.

    🐍 If your try: except code can't get validation - try to delete 'if name == 'main':'

    Probably this if statement triggers an error message reading it as part of "if (...) else") statement.

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