python - Python 获取公共 GitHub 存储库中的 csv 文件列表

Question

我正在尝试使用 Python从公共存储库中提取一些 csv 文件。在获得文件的 URL 后，我就有了处理数据的代码。是否有某种与lsGitHub 等价的东西？我在 GitHub 的 API 中没有看到任何内容，而且似乎可以使用 PyCurl，但是我需要通过 html 进行解析。有没有预建的方法来做到这一点？

BeautifulSoup（hacky 并且可能非常低效）解决方案：

# Import the required packages: 
from bs4 import BeautifulSoup
import requests
import pandas as pd
import re 

# Store the url as a string scalar: url => str
url = "https://github.com/CSSEGISandData/COVID-19/tree/master/csse_covid_19_data/csse_covid_19_daily_reports"

# Issue request: r => requests.models.Response
r = requests.get(url)

# Extract text: html_doc => str
html_doc = r.text

# Parse the HTML: soup => bs4.BeautifulSoup
soup = BeautifulSoup(html_doc)

# Find all 'a' tags (which define hyperlinks): a_tags => bs4.element.ResultSet
a_tags = soup.find_all('a')

# Store a list of urls ending in .csv: urls => list
urls = ['https://raw.githubusercontent.com'+re.sub('/blob', '', link.get('href')) 
        for link in a_tags  if '.csv' in link.get('href')]

# Store a list of Data Frame names to be assigned to the list: df_list_names => list
df_list_names = [url.split('.csv')[0].split('/')[url.count('/')] for url in urls]

# Initialise an empty list the same length as the urls list: df_list => list
df_list = [pd.DataFrame([None]) for i in range(len(urls))]

# Store an empty list of dataframes: df_list => list
df_list = [pd.read_csv(url, sep = ',') for url in urls]

# Name the dataframes in the list, coerce to a dictionary: df_dict => dict
df_dict = dict(zip(df_list_names, df_list))
