This displays the selection list on the phone screen with all the goods, allowing us to select all the items that need to be bought. The result of our selection is stored in the variable choices. It is a tuple that holds the indices of the selected items. A for loop reads the selected items from the foods list, based on the indices of the selected items in choices. We start with an empty list, shoppinglist, to which we add the required items during each SUMMARY 47 iteration of the for loop. ’. If the user chooses to add a greeting, the string is added to the shopping list.
4 Application Building and SMS Inbox Python for S60 gives you easy access to the framework for building user interfaces on the S60 platform. Thanks to PyS60’s simple way of handling this, you learn how to build a real application that includes a title bar, a menu and some dialogs in around 15 lines of code! We start by describing how functions are deﬁned in Python. 2, which also presents an overview of the structure of a typical S60 application. In addition, this section introduces one of the most important concepts in PyS60, callback functions, which let you bind arbitrary actions to various events.
Note that you can reverse the outcome of the condition, by putting the not keyword in front of the condition. =, < and >, for equality, inequality, less than and greater than. ") NATIVE UI ELEMENTS – DIALOGS, MENUS AND SELECTION LISTS 39 Here, elif stands for ‘else if’. You can have multiple elif statements after each other. They are evaluated in sequence until one of the conditions evaluates to true. The indented statements that follow a condition are called a block. The ﬁrst unindented statement marks the end of the block.
