Also, some functionalities are much more complete in Qt, and there's more
consistency using a single (almost always) coherent framework than
different (external) modules, which differ by syntax, naming convention,
argument order and error handling.
Finally, a more comprehensive cross-platform support (for example regarding
path support, which always uses "/" and doesn't need complex handling with
os.path.join and os.path.sep).
