python爬取数据遇到的一些问题

Question

需要requests的网页
https://hugovk.github.io/top-pypi-packages/top-pypi-packages-30-days.min.json

raw_data=requests.get("https://hugovk.github.io/top-pypi-packages/top-pypi-packages-30-days.min.json%22)

1. Can you count the size/length of raw_data['rows'] . 将 raw_data['rows] 定义为新变量叫做 lib_data .
   2 打印 data type of each element of lib_data .
2. 打印 'download count' of each element in lib_data.

4.Traverse lib_data and create 字典数据 with keys library names ('project' in lib_data[i] dictionary) and values 为 'download count'.

打印 data['requests'] .

Answer 1

import requests

url = r'https://hugovk.github.io/top-pypi-packages/top-pypi-packages-30-days.min.json'

raw_data=requests.get(url)

lib_data = raw_data.json()['rows']
print(len(lib_data))
data = {}
for i in lib_data:
    print(i)
    print(type(i))
    print(i['download_count'])
    data[i['project']] = i['download_count']
print(data)
