[Tutor] getting back my listbox items
Hi, when i do search in my Entrybox the list lowers down to that typed item
the code of which i wrote in the update_list function. how should i get
listbox items back again after it has been lowered? and another question:
if i want to format some specific text in my Text widget i should use
BeautifulSoup or can i do that with add_tag method? i used add_tag method
in my enter_meaning function but it formats the first 4 letters of anyword,
but i want the words which are in the listofwords to be formatted.

(please, don't use attachments because they often get stripped by the mail server as a security risk.) Also the error message, from where it says Traceback to the end. It may look like gobbledegook to you but it does actually have a lot of useful information that can help us see what went wrong. Without those two things we are pretty much unable to help, so please repost with the missing info. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

Please pretend for a moment that you received your own email above.
Read it carefully. If you were trying to help this person, "Paula",
how would you answer the following questions?
1) Hmm. She is having a syntax error. This could be one of a large
number of possible syntax errors, each having a different cause.
Which syntax error might she be having?
2) She is doing lesson 3 from the book "Begin to Code with Python".
I don't own that particular book. I wonder what that lesson is about
and what specific problem(s) she is trying to solve?
3) How is she running her program? Is she running it directly from
the Python terminal? From a ".py" file?
4) I wonder what version of Python she is running? Python 2.X or
3.X? This might make a difference in how I answer her.
5) And what operating system is she using? This could be a factor, too.
Paula, I am *not* trying to be condescending! But your email as sent
is so vague I (and everyone else) has no idea how to help you. As an
example of the kind of information we need, I artificially generated a
syntax error of my own. If I were asking for help I would probably
say something like the following:
Hi folks! I am working on an egg timer challenge from the book "Begin
to Code with Python". In lesson 3 it asks me to query the user to
enter how many minutes he/she wants his/her egg boiled. I wrote the
following code in my Python interpreter:
py3: time = input("Please tell me how many minutes you want your egg to boil?)
, but I got the following error:
File "", line 1
time = input("Please tell me how many minutes you want your egg to boil?)
^
SyntaxError: EOL while scanning string literal
I am using Python 3.6.5 on Windows 7-64 bit. I was trying to get the
amount of time in minutes the user wanted me to boil the egg in my
"time" variable, but I got the above error. What am I doing wrong?
Do you think you might be able to answer my question?
Hope this helps us to help you, and we really do want to help!
Cheers!

It does this every time. So any items inserted at the end in earlier iterations will be deleted by later finds. Is that really what you want? > def entry_delete(self, tag): > self.entry_search.delete(0, tk.END) > return None Why do you have tag as a parameter when you don't use it? > def entry_insert(self, tag): > self.entry_search.delete(0, tk.END) > self.entry_search.insert(0, "Type to Search") > return None same here?
