Catching an unknown error

[Harlin Seritt]

Using the code below:

---BEGIN CODE---

value = raw_input("Type a divisor: ")
try:
value = int(value)
print "42 / %d = %d" % (value, 42/value)
except ValueError:
print "I can't convert the value to an integer"
except ZeroDivisionErr or:
print "Your value should not be zero"
except:
print "Something unexpected happened"

---END CODE---

In the last 'except' block, how can I print out the particular error
name even though one is not specifically named?

Thanks,

Harlin

Make the last 'except' block like this:

Except Exception, e:
print e

the sys.exc_info() function returns information about the current exception.
see:

while that's good enough for the given example, it's not good enough for
the general case (in contemporary Python, exceptions don't have to inherit
from the Exception class).

Thanks for pointing that out. I was following logic I was taught in
Hetland's book, which supposedly was up-to-date for Python 2.4.
Typical textbook error.

HarlinIn the last 'except' block, how can I print out the particular
Harlinerror name even though one is not specifically named?
