想把数据可视化出现报错了，请问有会的吗？
import requests
import pygal
from pygal.style import LightColorizedStyle as LCS, LightenStyle as LS

执行API调用并存储响应

url=' https://api.github.com/search/repositories?q=language:python&sort=stars' https://api.github.com/search/repositories?q=language:python&sort=stars%27
r = requests.get(url)
print("Status code:",r.status_code)

将API响应存储在一个变量中

response_dict=r.json()
print("Total repositors:",response_dict['total_count'])

探索有关仓库的信息

repo_dicts=response_dict['items']

names,stars=[],[]

print("Repositories returned:",len(repo_dicts))

研究第一个仓库

repo_dict = repo_dicts[0]

print("\nkeys:",len(repo_dict)):

for key in sorted(repo_dict.keys()):

print(key)

print("\nSelected information about each repository:")

for repo_dict in repo_dicts:
names.append(repo_dict['name'])
stars.append(['stargazers_count'])
#可视化
my_style=LS('#333360',base_style=LCS)
chart=pygal.Bar(style=my_style,x_label_rotation=45,show_legend=False)
chart.title='Most-Starred Python Projects on GitHub'
chart.x_labels=names

chart.add('',stars)
chart.render_to_file('python_repos.svg')

print('\nName:',repo_dict['name'])

print('Owner:',repo_dict['owner']['login'])

print('Stars:',repo_dict['stargazers_count'])

print('Repository:',repo_dict['html_url'])

print('Created:',repo_dict['created_at'])

print('Updated:',repo_dict['updated_at'])

print('Description:',repo_dict['description'])

进程已结束，退出代码为 1

stars.append(['stargazers_count'])
这一行似乎有点问题？改成这样：
stars.append(repo_dict['stargazers_count'])
