python csv linux urllib2

I am loading the data from url to csv file, how can we load it correctly? however, i got some python scripts to read the data but it is not loading the data,it is replacing the data within that file?

I am new to python so send 开发者_运维技巧me the documentation and also send me the code for getting and loading the data from html into csv file.

Advance in thanks.

No problem:

• csv library docs
• urllib2 library docs

For the second part, we would need to know what the data you're downloading looks like.
