#The truncation of the information should be possible by commands like (title:20) if I wanted to shorten it to 20 characters but not sure how to apply anything yet #Also tried the, stuff but the references are in a totally different context so I'm finding it difficult to apply them here. #Have found a way to replace text in the original text file but that's not what we want to do, we want the strings printed to be replaced so the spacing is correct. Tried things like file.replace(' ', ' ') but no success so far. split things seem to require a completely different setup here that makes the input not work at all. #This is where I will try and get the raw data from the text file to split and replace all the with a tab. At the very least it does successfully search for now. It needs to be able to find a book to be able to delete it, right? Probably a better way but I don't know. #This will be modified for the Delete command. A problem to figure out later.įile.write(bk.getTitle() + ' ' + bk.getAuthor() + ' ' + bk.getISBN() + ' ' + bk.getCallNumber() + ' ' + bk.getStock() + ' ' + bk.getLoaned() + ' ') #Doesn't work right now, gives some error about getTitle (and presumably every other get) not being defined. #This function probably doesn't work right now, not sure how to even apply it to anything and it's far secondary to the actual main problem.ĭef _init_(self, title, author, isbn, callnumber, stock, loaned): The main difficulty I'm having is around the display() function I'm trying to build. There are other goals (adding a new book, deleting a book, etc), but I can't even really begin working on them until this core part is done, and that's the part I'm having great difficulty with.įor reference, here is the entirety of my code so far. These need to be stored in a list of book objects and that list must be stored in a variable referred to as the inventory. These come from reading a text file called books.txt. I have to implement a custom class 'Book' with various properties (title, author, etc). For all the other coding I've been doing (Java, SQL, etc) I've been able to do it on my own but I've hit a wall on this Python task and no amount of Googling has helped me, and the course itself hasn't provided the materials to help me here (and I've been desperately looking!) Hello, having some difficulty with this Python work I've been given.
