Hi, I'm not too sure what your asking here,
your code assigns the following to endings: ['st', 'nd', 'rd', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'st', 'nd', 'rd', 'th', 'th', 'th', 'th', 'th', 'th', 'th', 'st'] This is what we would expect.. 17 * ['th'] causes 17 repetitions of 'th' in the list. certain operators, like the multiplication operator in your example, have additional behavior depending on what kind of data they are applied to. The repetition operator binds closer than the '+' as the following brackets show. endings = ['st', 'nd', 'rd'] + (17 * ['th']) + ['st', 'nd', 'rd'] + (7 * ['th']) + ['st'] Ian.
