Body
Keep in mind that I am still very new to python coding as I am only just into chapter 5 of my python coding class. Keeping that in mind, I am attempting to create a sum calculator using a "while loop" to continue until the user enters a negative number instead of a positive number. In case I am not entirely clear in my description of my question I will post the exact homework problem here: Chapter 5, page 200, #8 Sum of Numbers Write a program with a while loop that asks the user to enter a series of positive numbers. The user should enter a negative number to signal the end of the series. After all the positive numbers have been entered, the program should display their sum. Now for the code that I have written so far: <pre><code>def main(): number = float(input('Please enter in a positive number: ')) while number > 0: positiveNumber() while number < 0: calculateTotal() printTotal() def positiveNumber(): number = float(input('If you are finished please enter a negative number.' + \ 'Otherwise, enter another positive number: ')) while number > 0: positiveNumber() while number < 0: calculateTotal() printTotal() def calculateTotal(): total = 0 + number def printTotal(): print('The sum of your numbers is: ', total) main() </code></pre> <ul> <li>In line 11, I have the "+ \" sign there because I wanted to make an enter space there in order to have a cleaner looking text, but that does not seem to work.</li> </ul> I apologize if this question seems "nooby" but I need help making a cleaner/working sum calculator. I would greatly appreciate it if someone can take a look at this code and hopefully help me improve it. Thank you! Final Edit: Thank you all for the informative answers! I learned alot (for a "newbie" =]). I used Talon876's answer for my calculator. Thanks again everyone!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
