Exceptions Handling

When programming, errors happen. It’s just a fact of life. Python’s solution to errors are exceptions.
Errors detected during execution are called exceptions.

ZeroDivisionError

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

a = 1
b = 0
print (a/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

# prints Error Code: integer division or modulo by zero

Try the following excercise in the editor below.

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

1 <= T <= 10

Output Format

Print the value of a/b. In the case of ZeroDivisionError or ValueError, print the error code.

Example Input

3
1 0
2 #
5 2

Exaple Output

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