python爬取数据遇到的一些问题

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)

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 .
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'] .

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)

raw_data为上面网页的requests.get, 但不知道为啥复制粘贴的时候出现了打印错误.

{'download_count': 38076, 'project': 'redfish'},
{'download_count': 38074, 'project': 'pyobjc-framework-coredata'}, {'download_count': 38062, 'project': 'types-croniter'}, {'download_count': 38060, 'project': 'pulumi-aws'}, {'download_count': 38060, 'project': 'zconfig'}, {'download_count': 38057, 'project': 'nwdiag'}, {'download_count': 38051, 'project': 'google-cloud-dataflow-client'}]

比如得到的是这样的数据类型,如何打印download_count的值呢

用json.loads将字符串转换为json格式，遍历取出

第五步想要把数据改成project为key, download_count改为value,为啥这里显示attribute error.
data={}

for element in libdata:
data.keys=element["project"]
data.values=element["download_count"]
print(data)
