I need to get my_glossary to get the data from the txt file but when I add the data using the addNewWord function I get errors such as a syntax error inside the txt file saying that the {} or '' are the cause of the issue.

Python

    my_glossary = {}
# iterate through all lines, after removing the line-end character(s)
    for line in inText.splitlines():
        if line != '':           # ignore empty lines
            key,value = line.split(',')
            my_glossary[key] = value
 
    my_glossary['newkey'] = 'and the new value'

Please explain your problem in proper detail. We cannot guess what is in your mind.

Dylan Forsyth 28-Jan-15 15:15pm

I need to get my_glossary to get the data from the txt file but when I add the data using the addNewWord function I get errors such as a syntax error inside the txt file saying that the {} or '' are the cause of the issue....sorry for not being clear enough

Richard MacCutchan 28-Jan-15 15:30pm

You need to show which line of code causes the error, and provide the exact error message. Please don't expect us to be able to make guesses.

Dylan Forsyth 28-Jan-15 15:37pm

My new problem is the fact that the code wont read the txt file information as a dictionary so returns "There is no entry for this word." instead of the definition.....the contents of the text file are :

"test", "this is another test",

exactly like that^

Dylan Forsyth 28-Jan-15 15:20pm

changed the code but I cant seem to generate the dictionary from the code

Richard MacCutchan 28-Jan-15 15:37pm

I have tried running your code but I cannot figure out how is is supposed to run, or what is the format of the glossary file. I can only suggest you try working on each part individually until you get it working, and then put all the parts together.

Dylan Forsyth 28-Jan-15 15:40pm

Thanks...I am working on it for my school GCSEs (english major exams) so kinda need to get it working.....but I just cant figure out why it doesnt return the contents of the text file when I input the first part of the dictionary...so if I inputted "test"...I would expect the output below it to be "this is another test"

Richard MacCutchan 29-Jan-15 3:11am

Did you look at my code below? Take the quotes off your strings in the text file, and use the readline method to read each line from the file. You then repeat that until all lines have been read into your dictionary, although I am not sure how you test for end-of-file, but I expect you can easily find out.

Dylan Forsyth 29-Jan-15 10:30am

Thank you so much for your help although i am not sure how to get the information to go down a new line each time when you add a new word and definition...

Richard MacCutchan 29-Jan-15 11:29am

I've been playing with this today, have a look at solution 2. See also https://docs.python.org/3.3/tutorial/datastructures.html#dictionaries.

BTW 'O' or 'A' levels?

Dylan Forsyth 29-Jan-15 11:39am

It is like my O levels but I am the last year before it gets changed back to O levels...

Dylan Forsyth 29-Jan-15 11:44am

Do you want me to place the new solution under the older one or replace it?
Thanks again..You are awesome....I hope people who contribute to this website like normal people get some kind of benefits or something :D

Richard MacCutchan 29-Jan-15 12:02pm

Don't worry, as long as you have accepted it it will be fine. If it's any consolation, I am still learning Python, but my
programming background helps me to pick things up reasonably quickly. I had the advantage of 'knowing' conceptually how to read a file and build a set of dictionary entries. The difficulty was figuring out all the Python code to make it happen.

Dylan Forsyth 29-Jan-15 12:06pm

It is not working....where do you want me to activate the function?

Richard MacCutchan 29-Jan-15 12:14pm

Activate it anywhere in the beginning of the module, before you build the TK window, instead of the following two lines:


with open('glossary.txt','r') as inf:
    my_glossary = eval(inf.read())

Dylan Forsyth 29-Jan-15 12:23pm

I am still a little confused...could we use some kind of other thing like skype briefly? I think I have done it wrong...:(

Richard MacCutchan 29-Jan-15 12:36pm

Sorry, I only work through these forums.

As I said in a previous message, you need to build your program in steps. Test this code in isolation until you are comfortable that it works according to your requirements, and you fully understand how it works. The documentation link I gave you should also help. Once you have got that you can start building the rest of the app around it. The important thing is that you use the development process as a learning tool.

Dylan Forsyth 29-Jan-15 12:35pm

Actually can you just post all of the code into the solutions tab please

Richard MacCutchan 29-Jan-15 12:37pm

That is all the code I have. The rest of it is for you to do.

Dylan Forsyth 29-Jan-15 12:38pm

thanks

Dylan Forsyth 29-Jan-15 12:42pm

If I post the code into the post can you please just confirm that it is correctly placed...?

Dylan Forsyth 29-Jan-15 12:43pm

I added the new code onto the end of the main post

Richard MacCutchan 29-Jan-15 12:59pm

Why not use the code I gave you in my second solution? A quick glance at what you have posted suggests that it's not going to work. Reread my rather lengthy message just above this one.

Dylan Forsyth 29-Jan-15 13:26pm

I keep getting the error that there are too many values to unpack with your code at the point where you split the line at ","

Richard MacCutchan 30-Jan-15 4:55am

Check the content of your text file. Each line should be in the form
key,value field
with no quote characters and no commas in the value field.

Dylan Forsyth 30-Jan-15 10:29am

Thanks so much Richard...is there any way that I can give you some kind of points or something for the amount of amazing help you have given me..after doing some more research on other forums I found that I needed to make it:
key,value = line.split(',', 1)
and not:
key,value = line.split(',')

Thanks again...:D

Richard MacCutchan 30-Jan-15 11:46am

Don't woryy, just accept the solutions, we get points for that automatically. But we really try to answer questions here because we enjoy the challenge, and keeps our (old) brains working.

Dylan Forsyth 30-Jan-15 11:35am

Richard. One last thing. How do i get it so that it reads the txt file keys and I can input them without the need for capital letters, in other words can I make it so that I can make the words lower case and upper case in the input box and receive the same outcome?

Richard MacCutchan 30-Jan-15 11:48am

Take a look at the String Methods for help in modifiying the capitalisation.

Dylan Forsyth 29-Jan-15 11:52am

My New name will appear as Dylan Forsyth or Ddude...

See the following for reading the text file and creating a dictionary. Note you do not need quotes around your text in the glossary file. My file looks like:

foo,something silly
bar,something sillier

Code

Python

f = open('glossary.txt','r')
line = f.readline()
words = line.split(',')
dict = {}
dict[words[0]]=words[1]
line = f.readline()
words = line.split(',')
dict[words[0]]=words[1]

dict    # show the dictionary content

# output
{'foo': 'something silly\n', 'bar': 'something sillier\n'}

Richard MacCutchan · Accepted Answer · 2015-01-29T05:27:00

Python

def dictest():
# read all lines of the file
    inFile = open("glossary.txt", "r")
    inText = inFile.read()
    inFile.close()

    glossary = {}
# iterate through all lines, after removing the line-end character(s)
    for line in inText.splitlines():
        if line != '':           # ignore empty lines
            key,value = line.split(',')
            glossary[key] = value

    glossary['newkey'] = 'and the new value'

# list all the dictionary entries
    for k,v in glossary.items():
        print('key:', k, ', value:', v)
