Core Tasks

Now we're cooking. This section turns the language basics into useful programs: organise code, work with collections, shape strings and numbers, handle dates, read and write files, catch errors, and bundle files into archives.

What Do You Want to Make Easier?

• Build a well-shaped program: Start with code structure, then split the work into functions and procedures.
• Put data to work: Explore arrays, lists, and strings.
• Deal with everyday input: Try command-line parameters, dates and times, or regular expressions.
• Work with the filesystem: Learn about paths and filenames, file handling, and zip archives.

Each page is a standalone recipe, so follow your curiosity or jump straight to the problem you need to solve.
