If you want to do something that can take your Python coding ability to a different level, we suggest you go and take a challenge on Kaggle. Kaggle (www.kaggle.com) is a platform for predictive modeling and analytics competitions, which applies the idea of competitive programming (participants try to program according to the provided specifications) in data science by proposing challenging data problems to participants and asking them to provide possible solutions that are evaluated on a test set. The results of the test set are partly public, partly private.
The most interesting part for a Python learner is the opportunity to take part in a real problem with no obvious solution, which requires you to code ...
