Exceptions- Hacker Rank Solution

Exceptions

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  and .
Perform integer division and print .
Input Format
The first line contains , the number of test cases.
The next  lines each contain the space separated values of  and .
Constraints
Output Format
Print the value of .
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 //.

Problem Setter's code:
for i in range(int(raw_input())):
    try:
        a,b = map(int, raw_input().split())
        print a/b
    except ZeroDivisionError as e:
        print 'Error Code:',e
    except ValueError as e:
        print 'Error Code:',e
for i in range(int(input())):
    try:
        a,b = list(map(int, input().split()))
        print(a//b)
    except ZeroDivisionError as e:
        print('Error Code:',e)
    except ValueError as e:
        print('Error Code:',e)
