尝试迭代异常时出现错误

Question

我正在使用 PRAW 制作一个 Reddit 机器人，代码给了我异常不可迭代的错误。这是我的代码的简化：

try:
  #something with praw that isn't relevant
except Exception as e: #this except error catches the APIexception, APIexpections in PRAW are a wide field of exceptions that dont't always have the same solution, so I scan the text for the error I'm looking for.
  print(e)
  if "keyword thats in the error" in e:
    #fix the problem with the specific error
  else:
    print("Unkown APIExpection error")

这对我来说很好，但是当我运行这段代码时：

try:
  #something
except Exception as e:
  for character in e:
    print(character)

#I also tried this

try:
  #something
except Exception as e:
  for character in str(e):
    print(character)

#None of the above work but this is my actual code and what I need to do, anything that gets the above to work should work here too, I'm just letting you know this so that I don't get any other errors I have to ask another question for.

try:
  #something
except Exception as e:
  characterNum = 0
  for character in e:
    characterNum += 1
    print(str(characterNum) + ": " + character)

它给了我一个“TypeError: 'RedditAPIException' is not iterable”，RedditAPIException 可以忽略，因为这只是我遇到的错误。

将异常转换为字符串，然后检查 if 语句。

更改为 => if "keyword thats in the error" in str(e):
