I am trying to handle exceptions in Python 3.6. I want to handle every possible exception and print the exception. When i do 

try:
    raise RuntimeError("Test")

except:
    e = sys.exc_info()[0]
    print(e)

it just prints

class '_mysql_exceptions.OperationalError'

How do i get the message of the Exception? In this case i would like the output to be "Test".

You can catch and print the Exception as follows:

try:
    raise RuntimeError("Test")
except Exception as e:
    print(e)
    # Test

I'm not quite sure why you're trying to catch every Exception though, it would seem more prudent to let Python handle and raise these for you in general. Normally you would only catch specific Exceptions.

This behavior is not specific to Python 3.6.
