Output

Notes:

① tried for a long time, always hint

Unbound method must is called with instance as first argument

This error, finally added an instantiation statement in the lexicon.py, finally resolved

② Add points Exercise 3, identify the case with lower () all converted to lowercase and then judged

③ Add to exercise 4, another way is to manipulate the string in the try, except in the operation of the numbers.

Try:i.lower () passexcept Syntaxerror:pass
