问题 This is my first post. I am new at VBA but I'm pretty familiar with VB6. I wrote some code that takes the text from nasdaq and pastes it into a worksheet. It finally works. There is a lot of extraneous data scattered around above and below The Annual Income Statement. I would like to parse out and place the important data in a place where I can automate analysis. I'm thinking that I could search the cells until I find: Annual Income Statement and extract to a different sheet. Any suggestions

问题 I want to send HTML webpage as a mail body using Python and Flask. I tried using MIME module, but somehow I am not being able to send mail.

问题 I have a folder in my ftp server which contains several images. I'm trying to access and show these images in a webpage like <img src="ftp://my_ftp_ip_address/Images/imagename.jpg"/> But it asks for an FTP username and password. How can I achieve this?

And it was never a good solution anyway. The correct solution is to route

问题 I'm working on an old school linux variant (QNX to be exact) and need a way to grab a web page (no cookies or login, the target URL is just a text file) using nothing but sockets and arrays. Anyone got a snippet for this? note: I don't control the server and I've got very little to work with besides what is already on the box (adding in additional libraries is not really "easy" given the contraints -- although I do love libcurl) 回答1: I do have some code, but it also supports (Open)SSL so it's

问题 I have a webpage (built using HTML & jQuery) which displays the data from a MySQL database. I am using Flask to connect HTML with my database. However, my database gets updated every 15 minutes (using a separate Python Script). Currently, I stop the flask server, update the database and restart the Flask to update the webpage.

问题 Im trying to retrieve the charset from a webpage(this will change all the time). At the moment Im using beautifulSoup to parse the page and then extract the charset from the header. This was working fine until I ran into a site that had..... <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> My code up until now and which was working with other pages is: def get_encoding(soup): encod = soup.meta.get('charset') if encod == None: encod = soup.meta.get('content-type') if encod =

问题 I am writing a bot using Python with Selenium module.When I open a webpage with my bot, since the webpage contains too many external sources than dom, it takes a lot to get all of the page loaded.
