'UCS-2' 编解码器无法对位置 61-61 中的字符进行编码

'UCS-2' codec can't encode characters in position 61-61

当我 运行 我的 Python 代码和打印(项目)时,我得到以下错误:

UnicodeEncodeError: 'UCS-2' codec can't encode characters in position 61-61: Non-BMP character not supported in Tk

这是我的代码:

def getUserFollowers(self, usernameId, maxid = ''):
    if maxid == '':
        return self.SendRequest('friendships/'+ str(usernameId) +'/followers/?rank_token='+ self.rank_token,l=2)
    else:
        return self.SendRequest('friendships/'+ str(usernameId) +'/followers/?rank_token='+ self.rank_token + '&max_id='+ str(maxid))
def getTotalFollowers(self,usernameId):
    followers = []
    next_max_id = ''
    while 1:
        self.getUserFollowers(usernameId,next_max_id)
        temp = self.LastJson

        for item in temp["users"]:
            print(item)
            followers.append(item)

        if temp["big_list"] == False:
            return followers            
        next_max_id = temp["next_max_id"]

我该如何解决这个问题?

如果不知道 temp["users"] 的内容很难猜测,但错误表明它包含非 BMP unicode 字符,例如 emoji.

如果您尝试在 IDLE 中显示它,您会立即收到此类错误。重现的简单示例(在 Python 3.5 的 IDLE 上):

>>> t = "ab \U0001F600 cd"
>>> print(t)
Traceback (most recent call last):
  File "<pyshell#5>", line 1, in <module>
    print(t)
UnicodeEncodeError: 'UCS-2' codec can't encode characters in position 3-3: Non-BMP character not supported in Tk

(\U0001F600表示unicode字符U+1F600笑脸)

确实是Tk不支持code大于FFFF的unicode字符导致的错误。一个简单的解决方法是将它们从字符串中过滤掉:

def BMP(s):
    return "".join((i if ord(i) < 10000 else '\ufffd' for i in s))

'\ufffd' 是 unicode U+FFFD REPLACEMENT CHARACTER.

的 Python 表示

我的例子变成:

>>> t = "ab \U0001F600 cd"
>>> print(BMP(t))
ab � cd

因此您的代码将变为:

for item in temp["users"]:
    print(BMP(item))
    followers.append(item)
