您能帮我解决这个小问题吗?我正在寻找使用美丽的汤(Python)从以下代码中的SCRIPT标记(不在正文中)提取电子邮件,电话和姓名值。我是Python的新手,并且博客建议使用Beautiful汤进行提取。
我尝试使用以下代码获取页面-
fileDetails = BeautifulSoup(urllib2.urlopen('http://www.example.com').read())
results = fileDetails.find(email:")

该Ajax请求代码不再在页面中重复。我们还可以编写try and catch以便在页面中未找到它时不会引发任何错误。
<script type="text/javascript" language='javascript'>
$(document).ready( function (){
$('#message').click(function(){
alert();
});
$('#addmessage').click(function(){
$.ajax({
type: "POST",
url: 'http://www.example.com',
data: {
email: 'abc@g.com',
phone: '9999999999',
name: 'XYZ'
}
});
});

一旦得到这个,我也想存储在一个excel文件中。
谢谢您的期待。
如何在Python中使用XLWT或XLRD查找总行数?我有一个excel文件(accounts.xls),并希望在其中追加行.
我在这里收到错误 - AttributeError:'Sheet'对象没有属性'write'
from xlrd import open_workbook
from xlwt import Workbook
def saveWorkSpace(fields,r):
wb = open_workbook('accounts.xls')
ws = wb.sheet_by_index(0)
r = ws.nrows
r += 1
wb = Workbook()
ws.write(r,0,fields['name'])
ws.write(r,1,fields['phone'])
ws.write(r,2,fields['email'])
wb.save('accounts.xls')
print 'Wrote accounts.xls'
