python try except raise custom exception code example

Example 1: python custom exception

class UnderAge(Exception):
   pass
 
def verify_age(age):
   if int(age) < 18:
       raise UnderAge
   else:
       print('Age: '+str(age))
 
# main program
verify_age(23)  # won't raise exception
verify_age(17)  # will raise exception

>>> def catch():
...     try:
...         asd()
...     except Exception as e:
...         print e.message, e.args
... 
>>> catch()
global name 'asd' is not defined ("global name 'asd' is not defined",)
