Python Exceptions HackerRank 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 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
Solution:
for i in range(int(input())):
try:
a, b = map(int, input().split())
print(int(a//b))
except Exception as e:
print("Error Code:",e)
Steps Used in solving the problem -
Step 1: First we created a for loop in the range of integer input.
Step 2: In the second line, we used the try method. Inside try we have taken the input of a and b. Then we printed the division of a and b.
Step 3: At last we used except to handle exceptions i.e if there is any error occurred during compiling then the error will get printed and our code will work continuously.
