所以我在学习一个reddit到twitter的机器人教程,这个机器人是用python编写的,使用PRAW编写的,我遇到了一些错误。在
在命令控制台中运行此代码会在第74行中显示错误

access_token_secret = ' secret'

def strip_title(title):
if len(title) < 94:
return title
else:
return title[:93] + "..."
def tweet_creator(subreddit_info):
post_dict = {}
post_ids = []
print "[bot] Getting posts from Reddit"
for submission in subreddit_info.get_hot(limit=20):
post_dict[strip_title(submission.title)] = submission.url
post_ids.append(submission.id)
print "[bot] Generating short link using goo.gl"
mini_post_dict = {}
for post in post_dict:
post_title = post
post_link = post_dict[post]
short_link = shorten(post_link)
mini_post_dict[post_title] = short_link
return mini_post_dict, post_ids
def setup_connection_reddit(subreddit):

'monitoring %s' %(subreddit))

return subreddit

post_dict, post_ids = tweet_creator(subreddit)
tweeter(post_dict, post_ids)
def tweeter(post_dict, post_ids):

if found == 0:
print "[bot] Posting this link on twitter"
print post+" "+post_dict[post]+" #Python #reddit #bot"
api.update_status(post+" "+post_dict[post]+" #Python #reddit #bot")

time.sleep(30)
else:
print "[bot] Already posted"
if __name__ == '__main__':
main()
错误:
^{pr2}$我对代码和错误的理解是,它需要一个字符串来发送,但不知何故得到了整个密钥字典集。我认为通过将[post]参数发送到post_dict,它将能够为bot获取特定的post进行utalize,但是,它正在获取字典!在
有两行,74和75都调用post_dict[post],并且在调用post key时不初始化字典的值。在
在调用}。这将向您展示这些结构的外观,并使解决方案显而易见。在
tweeter
函数For循环中的串联之前,请尝试打印post
