错误：取消缩进与任何外部缩进级别不匹配（制作reddit机器人）[重复]

Question

所以，我对 Python 来说还是个新手。我尝试制作一个 Reddit 机器人，修复了大部分错误。但当我尝试修复它时，这个问题开始让我头疼。

print("String with \"best girl\" found in comment", str(comment.id))
IndentationError: unindent does not match any outer indentation level.

还有一个箭头指向代码中最后一个

)

。经过一番研究后，我发现没有任何帮助。再说一遍，我对编程完全陌生。

我的代码：

import praw
import config
import time
import os

def bot_login():
    print "Loggin in..."
    r = praw.Reddit(username = config.username,
            password = config.password,
            client_id = config.client_id,
            client_secret = config.client_secret,
            user_agent = "busterronitest's dog comment responder v0.1")
    print "Logged in!"

    return r

def run_bot(r, comments_replied_to):
    print "Obtaining 25 comments..."

    for comment in r.subreddit('TheTempleOfOchako').comments(limit=10):
        if "best girl" or "Best girl" in comment.body and comment.id not in comments_replied_to and comment.author != r.user.me():
            print("String with \"best girl\" found in comment", str(comment.id))
            comment.reply("We all know ochako is best girl, [Just look at her!](https://i.imgur.com/SuKe7l0.jpg) This action was performed by a bot, contact u/Monikas_Comin if you have any issues.")
            print("Replied to comment", str(comment.id))

            comments_replied_to.append(comment.id)

            with open ("comments_replied_to.txt", "a") as f:
                f.write(comment.id + "\n")

    print "Sleeping for 10 seconds..."
    #Sleep for 10 seconds...
    time.sleep(10)

def get_saved_comments():
    if not os.path.isfile("comments_replied_to.txt"):
        comments_replied_to = []
    else:
        with open("comments_replied_to.txt", "r") as f:
            comments_replied_to = f.read()
            comments_replied_to = comments_replied_to.split("\n")
            comments_replied_to = filter(None, comments_replied_to)

    return comments_replied_to

r = bot_login()
comments_replied_to = get_saved_comments()
print comments_replied_to

while True:
    run_bot(r, comments_replied_to)

实际上Python给出了不适当的错误消息。在您的代码中，您混合了空格和制表符。然而，这两种东西不应该在 Python 中混合。这是修改后的代码，所有制表符都替换为四个空格：

import praw
import config
import time
import os

def bot_login():
    print "Loggin in..."
    r = praw.Reddit(username = config.username,
            password = config.password,
            client_id = config.client_id,
            client_secret = config.client_secret,
            user_agent = "busterronitest's dog comment responder v0.1")
    print "Logged in!"
    return r

def run_bot(r, comments_replied_to):
    print "Obtaining 25 comments..."
    for comment in r.subreddit('TheTempleOfOchako').comments(limit=10):
        if "best girl" or "Best girl" in comment.body and comment.id not in comments_replied_to and comment.author != r.user.me():
            print("String with \"best girl\" found in comment", str(comment.id))
            comment.reply("We all know ochako is best girl, [Just look at her!](https://i.imgur.com/SuKe7l0.jpg) This action was performed by a bot, contact u/Monikas_Comin if you have any issues.")
            print("Replied to comment", str(comment.id))
            comments_replied_to.append(comment.id)
            with open ("comments_replied_to.txt", "a") as f:
                f.write(comment.id + "\n")

    print "Sleeping for 10 seconds..."
    #Sleep for 10 seconds...
    time.sleep(10)

def get_saved_comments():
    if not os.path.isfile("comments_replied_to.txt"):
        comments_replied_to = []
    else:
        with open("comments_replied_to.txt", "r") as f:
            comments_replied_to = f.read()
            comments_replied_to = comments_replied_to.split("\n")
            comments_replied_to = filter(None, comments_replied_to)

    return comments_replied_to

r = bot_login()
comments_replied_to = get_saved_comments()
print comments_replied_to

while True:
    run_bot(r, comments_replied_to)

还有一个建议：你最好切换到Python3，对Python2的支持即将结束。

Answer 2

存在缩进错误，因为当您以固定方式编码时，您在给出空格时犯了错误，这里就是例子

def fun():
    a = int(input('enter the first number'))
    b = int(input('enter the second number'))
    print(a+b)
fun()

这是完美的代码，但如果我们只在空间上进行这样的更改：

def fun():
    a = int(input('enter the first number'))
    b = int(input('enter the second number'))
        print(a+b)
fun()

注意这里的打印函数，我给了它另一个可用空间，现在这段代码给了我这样的错误：

IndentationError: unexpected indent

您可以通过检查您给出的原始代码和行间距来使其正确

Answer 3

您在第 22 行错过了一个选项卡。在

if

语句之后，您需要将代码从

if

缩进
缩进一级 这可能有效，尽管我不知道它是否符合您的代码目标

for comment in r.subreddit('TheTempleOfOchako').comments(limit=10): 
    if "best girl" or "Best girl" in comment.body and comment.id not in comments_replied_to and comment.author != r.user.me(): 
         print("String with \"best girl\" found in comment", str(comment.id))
         comment.reply("We all know ochako is best girl, [Just look at her!](https://i.imgur.com/SuKe7l0.jpg) This action was performed by a bot, contact u/Monikas_Comin if you have any issues.")
