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.

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
• 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.

Sample Input 0

3

Sample Output 0

2

Sample Input 1

za

Sample Output 1

Bad String

Explanation

Sample Case 0 contains an integer, so it should not raise an exception when we attempt to convert it to an integer. Thus, we print the 3.

Sample Case 1 does not contain any integers, so an attempt to convert it to an integer will raise an exception. Thus, our exception handler prints Bad String.

Given code

import sys

S = input().strip()

[zenberr]

try:
    print(int(input("Enter a string")))
except:
    print("Bad string")

[Edson-Rodrigo]

string = input(" Enter a word or number: ").strip()

try:
    number = int(string)
    print(number)
except ValueError:
    print('Bad String')

[JesusBel16]

inp = input()
try:
    inp = int(inp)
except:
    print("Bad string")
else:
    print(inp)

[AlfredoITS]

import sys

S = input("Enter a number or a word: ").strip()

try:
    print("The number is:", int(S))
except ValueError: 
    print(S,"is Bad String.")

String to Integer

s = input().strip()

try:
    print(int(s))
except:
    print("Bad string")

String to Int

# string to int using exception handling
def main():
    try:
        print(int(input("Enter a number: ")))
    except:
        print("Bad Number")

if __name__ == "__main__":
    main()
