Exceptions

_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 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

For integer division in Python 3 use //.}
