Once the basic syntax of these data types is learnt, you can start growing your Python knowledge which will let you to more and more interesting operations with string handling. Always remember that the main goa
Code that runs for too many steps (e.g., > 100) or for a long time (e.g., > 10 sec) shorten your codeto isolate exactly what operations you want to visualize e.g., make your numbers/strings smaller, arrays/lists shorter, your data structures contain fewer items, and your loops/...
While strict mode is safest for ensuring your application explicitly sets the correct encoding for all I/O operations, it can lead to program crashes when an exception is raised. $ python codecs_encode_error.py strict ERROR: 'ascii' codec can't encode character u'\u03c0' in position 4:...
