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: '#' 2
