This was pretty helpful. I wasnt able to get the first exercise, this helped explain it!

[coralfoliage]

extremely helpful, and concise. thank you again!

Does anyone else agree, that they where confused and lost upon arriving at exercise 4 in chapter eight in the py4e book? I would have never thought to use the append method. In my own opinion the book and instructional videos are a bit lacking in the explaining the power and importance of append. Also the debugging section at the end of each chapter explains how list.sort() won't work, and says refer to documentation online. I had to click through several hyperlinks before arriving at a explanation of sorted(). This is my second try at the book originally started it about 6 months ago but upon reaching chapter 10 I gave up because I was totally lost. I know this course is free, but I wonder if I should perhaps stop reading py4e and using the site and find another teaching program... Should I stick with it? Thanks everyone and good luck;>)

thanks a lot, good study,
a small note: 2nd exercise, I think not 'From:' but 'From '

[valeriagutierrez]

Thank you very much! I was stuck in exercise 4 but this video really helped.

[stephaniegu]

thanks so much! I can't solve exercise 4 and your video is really helpful!!

Thanks a lot. I was struggling and with needed help with 8.5. I must however tell you that the solution although correct, has a bit of a mistake. We're supposed to use From and not From:

[santiagocavanagh]

Thank's I was having an issue with ex4 where my list had nested lists in it.

[samuelstrul]

In the first ex with the romeo text you did it wrong because the output didnt match the one you were looking for bc it had a bunch of \n's in it

[bringonthemonsters]

the first one is wrong. the \n is never removed from the words 'break' 'moon' and 'grief' Can i get some help with that please?
the strip() is not working for me

[flaviobrienza]

sorry, in the second exercise I used .split() without ' '. My list is the same, but without spaces between e-mail addresses. Can you explain me why? Why if I put ' ' it gives me spaces while if I don't put it the result is different?

[sebastianmusso]

For C8-E6. What would be a good solution if the user enters 'done' as the first input?

[manishchoubey]

In Exercise 8.4. I am doing this. Please, anyone, tell where I am going wrong:
words = []
fname = input("Enter file name: ")
fhand = open(fname)
for line in fhand:
words = line.split()
for word in words:
if word not in words:
words.append(word)
words.sort()
print(words)

[uddeshyakumar]

i have go 27 lines correctly still its showing mismatch what to do?

[luxury]

exercise 8.5 i copied whole as you explain but still getting wrong answer.

[manishpatil]

giving output with some words having '\n' in it.
