Day16 - Exceptions, String to Integer (Python 3)

• URL : https://www.hackerrank.com/challenges/30-exceptions-string-to-integer/problem

• Objective
  • Today, we’re getting started with Exceptions by learning how to parse an integer from a string and print a custom error message. Check out the Tutorial tab for learning materials and an instructional video!
• Task
  • Read a string, S, and print its integer value; if S cannot be converted to an integer, print Bad String.

• Note: You must use the String-to-Integer and exception handling constructs built into your submission language. If you attempt to use loops/conditional statements, you will get a 0 score.

• Input Format
  • A single string, S.
• Constraints

  • 1 <=

    S

    <= 6, where

    S

    is the length of string .

  • S is composed of either lowercase letters (a-z) or decimal digits (0-9).
• Output Format
  • Print the parsed integer value of S, or Bad String if S cannot be converted to an integer.

문제풀이

• 입력되는 S가 문자형이면 Bad String, 숫자형이면 숫자를 출력하는 내용
• int형으로 변환되면 그대로 출력, 안되면 Bad String을 출력하는 코드를 짬
