Hi there, thanks for the video.

I am confused as to why " + url + " is needed to summon a variable into the 'cmd = ' expression.
When I tried this exercise, I didn't know that was a thing- so instead, I just wrote:
cmd = ' GET website HTTP/1.0\r\n\r\n.encode()
where website is the user's input stored as a string, and this still did not work.


can you explain why + _ + is necessary here, and from where in the lesson plan you learned this ?

as well, why do we need to take .encode() from the end of our ' cmd = '
expression and make a new line with it?

Thanks in advance, good video.

edit: is it because cmd = ' GET HTTP/1.0\r\n\r\n.encode()' is a literal string, so instead of substituting my variable for and sending, it just sends GET Yes? Ah. blegh.

edit2: you moved encode() to a new line because it was less complicated than reformatting the ' cmd = ' expression so that the concatenation of string + variable + string produced a final string which was then operated on by the .encode(). I made mine work by just adding brackets:
cmd = ('GET' + website + ' HTTP/1.0\r\n\r\n').encode()

In the other case where I wrote:
cmd = 'GET' + website + 'HTTP/1.0\r\n\r\n'.encode()
without the brackets, HTTP/1.0\r\n\r\n got encoded before being concatenated

xD SHIT

@07:30 On the 2nd assignment I thought the programm should cut the connection after it received 3000 characters. So I coded following:

counter = 0
while True:
data = mysock.recv(1)
if len(data) < 1: break
print(data.decode())
counter = counter + 1
if counter > 3000: break
print("Letters:", counter)
mysock.close()

Anyone else thinking too complicated? :D

Anyways, thanks for your tutorials!

I think there might be a mistake in the last exercise. there are more than 7 paragraphs startting with <p> and ending with </p>. I got 23 by doing this:
count = 0
for tag in tags:
print(tag)
count+=1
print(count)

How did you run the program? I am using atom text editor, Can u temme how to run in atom?

It's been a couple of years and it looks like Dr. Chuck changed some of the lessons for chapter 12. He has exercises regarding BeautifulSoup that aksonai doesn't cover.

[hakeemagbaje]

Please what data editor are you using?

[shashankgautam]

What is the purpose of adding '+' at the front and back of url in line 16 ?

[canaanyamashita]

Is it only me that is confused or is it pretty common
