Question

I learn object-oriented programming in python 3. I’ve some exception, for example:

try:
    self.result = (...)
except urllib.error.URLError as error:
    print(error)

Generally all variables in classes are prefixed with self. Adding self before error variable:

try:
    self.result = (...)
except urllib.error.URLError as self.error:
    print(self.error)

causes:

SyntaxError: invalid syntax

Shall I just skip self before variables containing reason of exception?

Answer 1

error is the name you gave the exception. It is not a member of your class and thus is not prefixed with self.
