Hi,
I am confused by the slice on ‘new_word’.
What we want is the ‘rest’ of word, word[1:len(word)]
isn’t it?
So, mutating new_word seems a bad idea, and I guess it only works because at the time new_word = word[1:len(new_word)]...
is called, new_word does not have a length yet,
so - the slice goes to the end of word because in fact no second slice parameter is given??
If new_word already existed, it would contain ‘ay’ etc and would be longer than ‘word’.
So, my question is, should we not better use new_word = word[1:len(word)]
? Thanks.
By saying that new_word is word plus a slice of new_word, we’re using the variable to define itself. I first tried this and it didn’t work. It ran when I replaced “new_word” with just “word.”
My edit is because I said it still worked somehow, but really it didn’t and I was a bit gaslighted because it saved the working code when I ran it again instead of updating it. I refreshed the page and ran the code again with “new_word” and it ran the following error:
Traceback (most recent call last): File “python”, line 9, in <module> NameError: name ‘new_word’ is not defined
I had a question, but just figured it out. Instead of deleting I’ll just leave this below in case anyone else makes the same mistake (which is actually a really simple one!)
Every time I put “new_word = [1:len(new_word)]” into the code
I receive an error message in the console:
new_word = new_word[1:len(new_word)]
^
(for the sake of clarity, the carrot is pointing to the “:”, I tried spacing it out correctly, but once it posts to the forums the carrot goes back to the beginning of the line)
Here is the full if statement with the problem
if len(original) > 0 and original.isalpha():
word = original.lower()
first = word[0]
new_word = [word + first + pyg]
new_word = new_word[1:]
print original
While the above code didn’t work, one I removed the brackets around [word + first + pig] in line 4, the code ran fine. Still trying to understand exactly why that is (I have an idea as to why that might cause an error, but I’m a little confused as to why it caused the particular error that it did). Anyways, if you run into this same problem remove the brackets around [word + first + pig] and your code should run fine.
if len(original) > 0 and original.isalpha():
word = original.lower()
first = word[0]
new_word = word + first + pyg
new_word = new_word[1:]
print original
Why do I have to set new_word equal to the slice [1:len(new_word)]?
I can set it only on print command and it works the same: print new_word[1:len(new_word)]
I am trying to find out what is wrong with my code compared to the correct one. I really can not find the difference and so the answer.
Thanks a lot for your help.
My code (incorrect one)
pyg = 'ay'
original = raw_input('Enter a word:')
if len(original) > 0 and original.isalpha():
word = original.lower()
first = word[0]
new_word = word + first + pyg
new_word = [1:len(new_word)]
else:
print 'empty'
pyg = 'ay'
original = raw_input('Enter a word:')
if len(original) > 0 and original.isalpha():
word = original.lower()
first = word[0]
new_word = word + first + pyg
new_word = new_word[1:len(new_word)]
else:
print 'empty'
Hey, so i just finished my code and checked it several times, comparing it to the solutions below this thread but it still doesn’t work!
This is my code:
pyg = ‘ay’
original = raw_input(‘Enter a word:’)
if len(original) > 0 and original.isalpha():
print original
word = original.lower()
first = word[0]
new_word = word + first + pyg
new_word = new_word[1:len(new_word)]
else:
print “empty”
Now if I run it and enter the message e.g. “Hello” it simply answers “Hello” aswell…
Edit:
so i redid all the steps and wont delete this in case someone happens to do thje same mistake -> so i left the definition of new_word as part of the if condition
Thank you. That was the one thing I kept missing. I had to ask it to print the “New Word” instead of the “Original”. That was the one thing I was missing. Thank you.
new_word variable need to contain the right string. As mentioned in the instruction, you need to slice new_word (all the way to the end of new_word), while you do all the way to the end of word
Could someone please explain to me what I´m doing wrong? I can still progress in the lesson however it is a bit frustrating to not be able to test your code and see what you just made…
Why I am getting this error “It looks like you printed the correct translation of “python”, but make sure to set new_word equal to the slice as well.” I could not understand ??
