刪除\ r和\ n的列表

我試圖從城市字典JSON API刪除\ r和\ n，但每次我使用應用re.sub我得到這個：刪除 r和 n的列表

expected string or buffer

我不是知道爲什麼，雖然，但這裏的代碼：

elif used_prefix and cmd == "udi" and len(args) > 0 and self.getAccess(user) >= 1: 
    try: 
    f = urllib.request.urlopen("http://api.urbandictionary.com/v0/define?term=%s" % args.lower().replace(' ', '+')) 
    data = json.loads(f.readall().decode("utf-8")) 
    data = re.sub(r'\s+', ' ', data).replace("\\","") 
    if (len(data['list']) > 0): 
     definition = data['list'][0][u'definition'] 
     example = data['list'][0][u'example'] 
     permalink = data['list'][0][u'permalink'] 
     room.message("Urban Dictionary search for %s: %s Example: %s Link: %s" % (args.title(), definition, example, permalink), True) 
    else: room.message("Word not found.") 
except: 
    room.message((str(sys.exc_info()[1]))) 
    print(traceback.format_exc())

這是回溯：

Traceback (most recent call last): File "C:\Users\dell\Desktop\b0t\TutorialBot.py", line 2186, in onMessage data = re.sub(r'\s+', ' ', data).replace("\\","") File "C:\lib\re.py", line 170, in sub return _compile(pattern, flags).sub(repl, string, count) TypeError: expected string or buffer

郵政全回溯，好嗎？ – inspectorG4dget

你的意思是'/ r'和'/ n'，它們是兩個字符的字符串還是'\ r'和'\ n'，它們分別是回車和換行符的轉義序列？ –

的問題是，你要使用re.sub上一個dict而不是一個字符串。此外，你的代碼在地方似乎有點混亂。試試這個：

import urllib2 
import json 
import re 

def test(*args): 
    f = urllib2.urlopen("http://api.urbandictionary.com/v0/define?term=%s" % '+'.join(args).lower()) # note urllib2.urlopen rather than urllib.request.urlopen 
    data = json.loads(f.read().decode("utf-8")) # note f.read() instead of f.readall() 
    if len(data['list']) > 0: 
     definition = data['list'][0][u'definition'] 
     example = data['list'][0][u'example'] 
     permalink = data['list'][0][u'permalink'] 
     return "Urban Dictionary search for %s: %s Example: %s Link: %s" % (str(args), definition, example, permalink) # returns a string 

print test('mouth', 'hugging').replace('\n\n', '\n') # prints the string after replacing '\n\n' with '\n'

結果：

Urban Dictionary search for ('mouth', 'hugging'): When you put a beer bottle in your mouth, and keep your mouth wrapped around it all day. Example: Josh: "mhmgdfhwrmhhh (attempts to talk while drinking a beer)" 
Ryan: "You know I can't hear you when you're mouth hugging." 
Josh: "mmmffwrrggddsshh" Link: http://mouth-hugging.urbanup.com/7493517
