python生成github中Js的按Stars排序報表

python學習實踐，根據github的API獲取某個語言的項目列表生成圖表

通過python的requests模塊，對github的https://api.github.com/search/repositories?q=language:javascript&sort=starts接口進行請求，來獲取我們需要搜索的語言數據。如果需要獲取其他語言的數據，只要修改API的javascript爲想要查看的語言即可。

具體代碼：

import requests
import pygal
from pygal.style import LightColorizedStyle as LCS, LightenStyle as LS

url = 'https://api.github.com/search/repositories?q=language:javascript&sort=starts'

r = requests.get(url)
print('Status code: ', r.status_code)

response_dict = r.json()


print('Total repositories: ', response_dict["total_count"])

repo_dicts = response_dict['items']

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

# names, stars = [], []
names, plot_dicts = [], []

print('\n Selected information about first respository:')

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


my_style = LS('#333366', base_style=LCS)

my_config = pygal.Config()
my_config.x_label_rotation = 45
my_config.show_y_guides = False

chart = pygal.Bar(my_config, show_legend=False)
chart.title = 'Most-Starred Python Projects onn GitHub'
chart.x_labels = names

chart.add('stars', plot_dicts)
chart.render_to_file('python_respos.svg')

通過requests.get(url)獲取我們需要的數據，通過pygal.Bar創建一個圖標，先列表一下my_config都代表什麼意思。

• pygal.Config(): 創建一個Pygal類Connfig的實例
• x_label_rotation: 讓標籤繞x軸旋轉度數
• show_y_guides: 隱藏x軸上的水平線

方法add()接收一個字符串和一個列表，render_to_file()這裏我讓其生成一個svg文件，列表的效果圖如下：
