问题遇到的现象和发生背景
在python编程从入门到实践这本书中,第十七章,可视化仓库。我按照书上写下来的东西,为什么一直报错说 值无效。没明白
问题相关代码,请勿粘贴截图
import requests
from plotly.graph_objs import Bar
from plotly import offline
# 执行API调用并存储响应。
url='https://api.github.com/search/repositories?q=language:python&sort=stars'
headers={'Accept':'application/vnd.github.v3+json'}
r=requests.get(url,headers=headers)
print(f"Status code:{r.status_code}")
# 处理结果。
response_dict=r.json()
repo_dicts= response_dict['items']
repo_names,stars = [],[]
for repo_dict in repo_dicts:
repo_names.append(repo_dict['name'])
stars.append(repo_dict['stargazers_count'])
# 可视化。
data = [{
'type':'bar',
'x':'repo_names',
'y':'stars',
}]
my_layout = {
'title':'Github上最受欢迎的python项目',
'xaxis':{'title':'Repository'},
'yaxis':{'title':'Stars'},
}
fig = {'data':data,'layout':my_layout}
offline.plot(fig,filename='python_repos.html')
运行结果及报错内容
ValueError:
Invalid value of type 'builtins.str' received for the 'x' property of bar
Received value: 'repo_names'
The 'x' property is an array that may be specified as a tuple,
list, numpy array, or pandas Series
