HackerRank Python Solution - Errors and Exception

Errors detected during execution are called exceptions.

Examples:

ZeroDivisionError:

This error is raised when the second argument of a division or modulo operation is zero.

 

>>> a = '1'
>>> b = '0'
>>> print int(a) / int(b)
>>> ZeroDivisionError: integer division or modulo by zero

ValueError:

This error is raised when a built-in operation or function receives an argument that has the right type but an inappropriate value.

 

>>> a = '1'
>>> b = '#'
>>> print int(a) / int(b)
>>> ValueError: invalid literal for int() with base 10: '#'

Handling Exceptions:

The statements try and except can be used to handle selected exceptions. A try statement may have more than one except clause to specify handlers for different exceptions.

 

#Code
try:
    print 1/0
except ZeroDivisionError as e:
    print "Error Code:",e

Output:

Error Code: integer division or modulo by zero.

Task:

• You are given two values a and b.

• Perform integer division and print a/b.

Input Format:

• The first line contains T, the number of test cases.

• The next T lines each contain the space-separated values of a and b.

Constraints:

• 0 < T < 10

Output Format:

• Print the value of a/b.

• In the case of ZeroDivisionError or ValueError, print the error code.

Sample Input:

3
1 0
2 $
3 1

Sample Output:

Error Code: integer division or modulo by zero
Error Code: invalid literal for int() with base 10: '$'
3

Note: For integer division in Python 3 use //.

Solution:

T = int(input())

for _ in range(T):
    
    try:
        a,b = list(map(int,input().split()))
        print(a//b)
    except Exception as e:
        print("Error Code:",e)
