  1. PO.split(",") separating every character of a string
    text
    copied!<p>At some point of the program I ask it to take the user's text input and separate the text according to it's commas, and then I <code>",".join</code> it again in a txt file. The idea is to have a list with all the comma separated information.</p> <p>The problem is that, apparently, when I <code>",".join</code> it, it separates every single character with commas, so if I've got the string <code>info1,info2</code> it separates, getting <code>info1 | info2</code>, but then, when joining it back again it ends like <code>i,n,f,o,1,,,i,n,f,o,2,</code> which is highly unconfortable, since it get's the text back from the txt file to show it to the user later in the program. Can anyone help me with that?</p> <pre><code> categories = open('c:/digitalLibrary/' + connectedUser + '/category.txt', 'a') categories.write(BookCategory + '\n') categories.close() categories = open('c:/digitalLibrary/' + connectedUser + '/category.txt', 'r') categoryList = categories.readlines() categories.close() for category in BookCategory.split(','): for readCategory in lastReadCategoriesList: if readCategory.split(',')[0] == category.strip(): count = int(readCategory.split(',')[1]) count += 1 i = lastReadCategoriesList.index(readCategory) lastReadCategoriesList[i] = category.strip() + "," + str(count).strip() isThere = True if not isThere: lastReadCategoriesList.append(category.strip() + ",1") isThere = False lastReadCategories = open('c:/digitalLibrary/' + connectedUser + '/lastReadCategories.txt', 'w') for category in lastReadCategoriesList: if category.split(',')[0] != "" and category != "": lastReadCategories.write(category + '\n') lastReadCategories.close() global finalList finalList.append({"Title":BookTitle + '\n', "Author":AuthorName + '\n', "Borrowed":IsBorrowed + '\n', "Read":readList[len(readList)-1], "BeingRead":readingList[len(readingList)-1], "Category":BookCategory + '\n', "Collection":BookCollection + '\n', "Comments":BookComments + '\n'}) finalList = sorted(finalList, key=itemgetter('Title')) for i in range(len(finalList)): categoryList[i] = finalList[i]["Category"] toAppend = (str(i + 1) + ".").ljust(7) + finalList[i]['Title'].strip() s.append(toAppend) categories = open('c:/digitalLibrary/' + connectedUser + '/category.txt', 'w') for i in range(len(categoryList)): categories.write(",".join(categoryList[i])) categories.close() </code></pre>
