《Python编程：从入门到实践》学习记录（17）项目-使用ap

• 安装requests: pip install --user requests
• 需求: 抓取https://api.github.com/search/repositories?q=language:python&sort=stars的数据并绘制柱状图
  • 学习requests库的使用
  • 学习pygal绘图

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


def download_data(url: str):
    """下载api数据"""
    response = requests.get(url, timeout=None)
    print("响应状态码为: " + str(response.status_code))
    resp_json = response.json()
    items = resp_json["items"]
    rep_names, rep_star_count, rep_fork_count, rep_open_issue_count = [], [], [], []
    for item in items:
        rep_names.append(item["name"])
        rep_star_count.append(item["stargazers_count"])
        rep_fork_count.append(item["forks_count"])

            "open_issues_count": rep_open_issue_count}

    # x轴文本旋转45度，展示图例
    chart = pygal.Bar(style=my_style, x_label_rotation=45, show_legend=True)
    chart.title = "Github上最受欢迎的python项目"
    chart.x_labels = json_date["rep_names"]
    chart.add("star数量", json_date["rep_star_count"])

    chart.render_to_file('github-python.svg')


url = "https://api.github.com/search/repositories?q=language:python&sort=stars"
result = download_data(url)
draw(result)
