以下代码调试通过:
import pandas as pdimport json
demo = '{"programmers": [{"firstName": "Brett","lastName": "McLaughlin","email": "aaaa"}, { "firstName": "Jason","lastName": "Hunter","email": "bbbb"}, {"firstName":"Elliotte","lastName": "Harold","email": "cccc"}],"authors": [{"firstName": "Isaac","lastName": "Asimov","genre": "sciencefiction"}, {"firstName": "Tad","lastName": "Williams","genre": "fantasy"}, {"firstName": "Frank","lastName": "Peretti","genre": "christianfiction"}],"musicians": [{"firstName": "Eric", "lastName": "Clapton","instrument": "guitar"}, {"firstName": "Sergei","lastName": "Rachmaninoff","instrument": "piano"}]}'
demojs = jsonloads(demo)
print('\n', 'demojs: ', demojs)
Aurdata = pdDataFrame(demojs['authors'])
print('\n', 'Aurdata:\n', Aurdata)
一,检查pip有没安装cryptography,pyOpenSSL,certifi
pip install cryptography
pip install pyOpenSSL
pip install certifi
二,添加ssl验证
import ssl
ssl_create_default_>
DSN
=
'PROVIDER=MicrosoftJetOLEDB40;DATA
SOURCE=D:\Datamdb;'
把D:\Datamdb改成d:\\Datamdb就行了。
python里面\是个特殊的释放符号。
推荐在字符串前面加上r标志。标识字符串是原生态,里面的释放符号都是原始符号
;)
推荐这样写:
DSN
=
r'PROVIDER=MicrosoftJetOLEDB40;DATA
SOURCE=D:\Datamdb;'
四中方法:
'''
得到当前页面所有连接
'''
import requests
import re
from bs4 import BeautifulSoup
from lxml import etree
from selenium import webdriver
url = '>
