How does thid work?

Here is a email scraper:

#Ok, I know what line 0ne does:
import re
#Line 2 I know what is does:
import urllib2
#Line 3 res is a var = to urllib2.urlopen function
res=urllib2.urlopen('http://www.networksecuritybybluedog.com')
#line 4 a var text= res.read function this read the var res load it in to the var text I think.
txt = res.read()
#line 5 a var named email + re.findall function what it is looking for, in this case it is emails address.
emails=re.findall(r'[\w\.-]+@[\w\.-]+',txt)
#line 6 a for loop going through all the email it findes
for email in emails:
#line 7 this prints out the email address
    print "email"

I put commits in the code above of what I think each line of script does.
Could some who know what they are doing read the commits and let me know if I am right or wrong.
Thank You

the last line i believe you mean

email

and not

"email"

You want to print the value of email, not the actual string "email"

res is actually an instance of urlopen()
https://docs.python.org/2/library/urllib...b2.urlopen

read is a method that reads X number of bytes, with no args is the entire thing
https://docs.python.org/2/library/urllib2.html#examples

Thank you, yes I see what I did wrong, that is why it print out the string email and not the address.
But now it does print the address
I am happy
