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.

• 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)

``````
