Hey guys,
So I have a question regarding the split() function in the string
module. Let's say I have an string...
input = "2b 3 4bx 5b 2c 4a 5a 6"
projectOptions = (input.replace(" ", "")).split('2')
print projectOptions
['', 'b34bx5b', 'c4a5a6']
My question is, why is the first element of proj

I am screen-scraping a table. The table has an unknown number of rows,
but each row has exactly 8 cells. I would like to extract the data
from the cells, but the first three cells in each row have their data
nested inside other tags.
So I have the following code:

First of all, the string module is pretty much deprecated nowadays. What

It was a partial quote, that's why it appeared to be wrong:

I have some HTML such as
blah blah blah
I wnat to pull out the text that lies inside the quotes of the src

Is there any easy way to transfer 4 bit integer on socket?
I want to send like this:
a=5
send_integer(socket_s,a)
and receive like this:
a=receive_integer(socket_s)
Sending and receiving is in binary form, not transfer it to string.
Is there any easy way to do this?
