Python 和 pylast - AttributeError : 'NoneType' object has no attribute 'encode' python

Question

我是一个刚刚开始学习Python的完全菜鸟。我正在使用 Last.fm 的 pylast 库来提取用户邻居及其一些属性的列表，但是当我尝试打印邻居的国家/地区时，出现以下错误:

thrillofme
None
0
Traceback (most recent call last):
  File "/Users/Moi/DSR/Week 2/My tutorials/my-lastfm-thing-3.py", line 24, in <module>
    print country
  File "/Library/Python/2.7/site-packages/pylast.py", line 944, in r
    return _string(funct(*args))
  File "/Library/Python/2.7/site-packages/pylast.py", line 3497, in _string
return text.encode("utf-8")
AttributeError: 'NoneType' object has no attribute 'encode'

查看此错误消息的其他一些解决方案，我的印象是 country 未正确编码以进行打印，但我不太清楚该怎么办。任何帮助将不胜感激!这是我的代码。

import pylast

api_key = "XXX"
username = "Strangelove"
network = pylast.LastFMNetwork(api_key = api_key)
user = pylast.User(username, network)

# Let's pull a list of the specified user's Last.fm neighbours.
# Neighbours are users with a similar taste in music.

neighbours = user.get_neighbours()

for i in neighbours:
    gender = i.get_gender()
    age = i.get_age()
    country = i.get_country()
    print i
    print gender
    print age
    print country

Answer 1

缺少国家/地区名称，但 pylast 库未正确处理该情况。您必须自己测试空国家/地区的情况:

if country.name:
    print country
