    <p>I a new comer to programming (<strong>python</strong>) and have been doing some recent homework but I'm really stuck on this simple function implementation. Essentially, I have to ask for user input executed in the main() then define another function to work out the calculation with variables assigned to the user input. When run in IDLE, it outputs 0. Any help or hints will be immensely helpful, thankyou. Here is the code I have so far:</p> <pre><code>#global variables firstClass = 0.0 businessClass = 0.0 economyClass = 0.0 soldFirstClass = 0.0 soldBusinessClass = 0.0 soldEconomyClass = 0.0 totalFC = 0.0 totalBC = 0.0 totalEC = 0.0 ###################################### ###########MAIN FUNCTION############# ###################################### def main(): print('***WELCOME***\n') print('***Please ENTER the Airlines ticket prices***\n') firstClass = float(input ('Please ENTER a ticket price for First Class: ')) businessClass = float(input ('Please ENTER a ticket price for Business Class: ')) economyClass = float(input ('Please ENTER a ticket price for Economy Class: ')) print('\nThank You\n') soldFirstClass = float(input ('Please ENTER the number of sold tickets for First Class: ')) soldBusinessClass = float(input ('Please ENTER the number of sold tickets for Business Class: ')) soldEconomyClass = float(input ('Please ENTER the number of sold tickets for Economy Class: ')) calcClass() def calcClass(): global firstClass, soldFirstClass, businessClass, soldBusinessClass, economyClass, soldEconomyClass totalFC = firstClass*soldFirstClass print('Total money earned for First Class = %0.0f ') % totalFC totalBC = businessClass*soldBusinessClass print('Total money earned for Business Class = %0.0f ') % totalBC totalEC = economyClass*soldEconomyClass print('Total money earned for Economy Class = %0.0f ') % totalEC main() </code></pre>

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.
