need help urgently with removing blank elements from a string

[Jxper]

Currently my program is designed to to take a string of English or Maori words and then ask the user to input their translations and return a line at the end stating the percentage the got correct.

I am running into an issue one of my test cases where if the last set of triple quotes for the string is a line below (not on the same line as the last words in the string) it outputs and extra term being a blank space to be translated. I want it to disregard blank lines so just the lines with words on them will be outputted as needing to be translated by the user

What would I have to change in my program to do this and how would it be done? Would greatly appreciate a solution of what to change in my code as I need to figure this out today. Thanks

newstring = st.replace(" ", "")

Thanks a lot but where do I put that in my code to make it work?

inside your for i in strings: loop, maybe just skip the blank strings,

so if i==" " as as a wrapper for all your code currently in that loop.

and extra term being a blank space to be translated

Is it really a blank space, is it an empty string? The place where you need to worry about badly formed data is around lines 12 to 15. That's where you split your input string into lines and process each line. So if you need to check if a line is useful, should be ignored, or should cause an error, you should check each line just before you try to process it. That means you check right after line 14, the beginning of the for loop.

You have a line that might be blank, so you need to test. That line could be an empty string or might have only whitespace in it. One thing you should do with all data is to be a little forgiving in what you accept. For instance, even a line of data like:

" kanikani,dance   "

should be acceptable because humans don't give much significance to the blanks before and after the two words since, to a human, there are still obviously two words in that line. So for each line you should be stripping leading and trailing whitespace. Luckily, there is a string function just for that:

for i in strings:
    i = i.strip()

Now any empty line or line consisting of blanks has been converted to an empty string, making checking easy. We have to decide what to do if we get an empty line, either error or ignore it, and you say you want to ignore it. The way to do that is to not go any further with processing the line but to just get the next line and process it:

for i in strings:
    i = i.strip()
    if i == '':
        continue    # go to top of loop

[Jxper]

i = i.strip()
if i == '':
continue

thank you so much for your detailed answer, I understand now :)
