## Problem: Exceptions Hacker Rank Solution

Exceptions

Errors detected during execution are called exceptions.
Example :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.

• 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 //.

### Exceptions Hacker Rank Solution in python 2

``````for t in xrange(int(input())):
try:
a,b = map(int,raw_input().split())
print a/b
except ZeroDivisionError as e:
print "Error Code: %s" % e
except ValueError as e:
print "Error Code: %s" % e ``````

### Exceptions Hacker Rank Solution in python 3

``````# Enter your code here. Read input from STDIN. Print output to STDOUT
for i in range(int(input())):
try:
a,b=map(int,input().split())
print(a//b)
except Exception as e:
print("Error Code:",e)``````

``````# Enter your code here. Read input from STDIN. Print output to STDOUT
#from __future__ import division
for i in xrange(input()):
try:
a,b = map(int, raw_input().split())

except Exception as e:
if isinstance(e, ZeroDivisionError):

stringy.insert(2, "or")
stringy.insert(3, "modulo")
print 'Error Code:'," ".join(map(str, stringy))
else:
print 'Error Code:',e``````

# Enter your code here. Read input from STDIN. Print output to STDOUT

from sys import stdin,stdout

for i in range(0,int(n)):
a,b = line.split(" ")

try:

except ZeroDivisionError as e:
print("Error Code: {}".format(e))
except ValueError as e:
print("Error Code: {}".format(e))``````
