How to catch an exception
Catch exception
In case of an exception we can catch the exception and provide logic of to handle the exception.
The basic syntax of exception handling is
try
some code to raise exception
except ExceptionClassName
exception handler statements
try statement encloses pieces of code where one or more known exceptions may occur
try:# w w w .ja v a 2 s . c o m
1/0
except ZeroDivisionError:
print "Can't divide anything by zero."
try:
x = input('Enter the first number: ')
y = input('Enter the second number: ')
print x/y
except ZeroDivisionError:
print "The second number can't be zero!"
The code above generates the following result.
Catching the exception object
If you want access to the exception itself in an except clause, you can use two arguments.
try: # from ww w. j ava2s . co m
x = input('Enter the first number: ')
y = input('Enter the second number: ')
print x/y
except (ZeroDivisionError, TypeError), e:
print e
The code above generates the following result.
