为什么我的代码没有编译

Question

我正在学习 Python 并决定编写一个非常简单的 Python 机器人来在 Reddit 上回复。

编译时出现以下错误：

File "C:\Python35\Scripts\RedditBot\Reddit.py", line 28 except attributeerror: ^ SyntaxError: invalid syntax

我看不出是什么原因造成的，因为代码对我来说是正确的。

import praw

USERAGENT = "BOT Name"
USERNAME = "Username"
PASSWORD = "Password"
SUBREDDIT = "Subreddit"
MAXPOSTS = 100

SETPHRASES = ["Phrase", "PhraseOne"]
SETRESPONSE = "This is the response."

print('Logging in to Reddit')
r = praw.Reddit(USERAGENT)
r.login (USERNAME, PASSWORD)

def replybot():
    print('Fetching Subreddit ' + SUBREDDIT)
    subreddit = r.get_subreddit(SUBREDDIT)
    print('Fetching comments')
    comments = subreddit.get_comments(limit=MAXPOSTS)
    for comment in comments:
        try:
            cauthor = comment.author.name
            cbody = comment.body.lower()
            if any(key.lower() in cbody for key in SETPHRASES):
                print("Replying to " + cauthor)
                comment.reply(SETRESPONSE)
            except attributeerror:
                pass
replybot()

Answer 1

您有两个问题。

traceback中显示的第一个是缩进。 "try" 和 "except" 必须处于同一缩进级别。
第二个是对属性错误的引用。它需要像 AttributeError 中那样进行驼峰式命名。

因此，您的 for 循环内部应如下所示：

try:
   cauthor = comment.author.name
   cbody = comment.body.lower()
   if any(key.lower() in cbody for key in SETPHRASES):
      print("Replying to " + cauthor)
      comment.reply(SETRESPONSE)
except AttributeError:
   pass
