Python 3.x 属性错误：'；非类型'；对象没有属性'；解码'；

*如果我运行此操作，将出现错误

names, plot_dicts = [], []
for repo_dict in repo_dicts:
    names.append(repo_dict['name'])
    plot_dict = {
        'value': repo_dict['stargazers_count'],
        'label': repo_dict['description'],
        'xlink': repo_dict['owner']['html_url'],
        }
    plot_dicts.append(plot_dict)

my_style = LS('#333366', base_style=LCS)
chart = pygal.Bar(style=my_style, x_label_rotation=45, show_legend=False)
chart.title = 'Most-Stared Python Project On Github'
chart.x_labels = names
chart.add('', plot_dicts)

chart.render_to_file('new_repos.svg')

*我不知道为什么，有人能帮我解决这个问题吗

names, plot_dicts = [], []
for repo_dict in repo_dicts:
    names.append(repo_dict['name'])
    plot_dict = {
        'value': repo_dict['stargazers_count'],
        #'label': repo_dict['description'],
        'xlink': repo_dict['owner']['html_url'],
        }
    plot_dicts.append(plot_dict)

像上面一样尝试str（），您以前获得的数据似乎没有明确说明“description”存储的值的类型

可能是API与描述不匹配，因此您可以使用

ifelse

来解决此问题。就这样

'label':str(repo_dict['description'])

---

如果web API返回值

null

，则表示没有结果，因此可以使用If语句来解决。也许在这里，物品

shadowsocks

没有返回任何东西，所以可能是出了问题

错误为文本会更好。仅代码的答案不被认为是好答案。请通过提供更多的上下文和解释来改进您的答案。

description = repo_dict['description']
if not description:
    description = 'No description provided'

    'value': repo_dict['stargazers_count'],

plot_dicts.append(plot_dict)`
