Mobile Programming using PyS60: Advanced UI Controls In an earlier article I wrote, the topic of discussion covered the basic UI controls that PyS60 provides. These controls are useful when the solution to be developed is simple in terms of interaction. However, if a scenario presents itself where interaction becomes complex, then the basic controls would not suffice. Keep reading to learn about the advanced controls you'll need to deal with these kinds of issues.

Mobile Programming in Python using PyS60: UI Controls In this discussion I will focus on the basics of using a UI library provided by PyS60. The first section will focus on the types of controls. The second and third sections will be about two basic controls – query and note. In the fourth section, a simple application will be developed that uses the controls discussed in the second and third sections. That’s the agenda for this discussion. Python: Count on It We touched on how numbers work in Python a while back in the beginning of our series on Python. In the past few tutorials we discussed strings and how to manipulate them and some of the string methods. Here, in this article, we will go over some of the math modules and discuss different uses for numbers in Python. Python Strings: Spinning Yarns As the students used to say to Mr. Kotter: Welcome back, welcome back, welcome back. In our previous article we talked some more about how to manipulate strings in Python, leaving off with indexing and slicing. Here, we will pick up again with slicing, using it to “change” the contents of a string. Python: More Fun with Strings In our last article we left off discussing ways to manipulate strings in Python, like concatenating, repeating, escape characters, and so forth. In this episode we will pick up where we left off and learn some more ways to work with strings, starting with the comparison method. Python: Stringing You Along If you have ever programmed before, or are a ninety-year-old lady, or a cat, then you know how useful strings are. If you have been reading these articles, you will know that a string is a character, a sentence, a paragraph, a book, etc. If you haven't been reading these articles, then you're missing an important part of your education as a programmer. Don't keep yourself in the dark; start reading!
