I'm a beginner in Python programming, I just learned how to develop common data structures in Python with GUI features. Now I want to develop a creative project in Python. Can you give some great ideas or topics?
To develop a Python application with some GUI features you can use PyGTK (Python library for work with GTK), wxPython (cross platform library for building user interfaces) or wxSide (Python bindings for work with Qt library). There are a lot of tutorials and documentation on the official websites of any of those graphic toolkits. You can create any application to learn how to make user interfaces. There can be only one advice - make something you can use yourself, make it easy and small. Then you can improve new features after some experience with your programming skills.
