The method 'str'.isdigit() will always return the same T/F as isdecimal() or there is some difference in the algorithm of these methods?

It is mainly about Unicode classifications. See some examples to show discrepancies:

>>> def spam(s):
...     for attr in 'isnumeric', 'isdecimal', 'isdigit':
...         print(attr, getattr(s, attr)())
...         
>>> spam('½')
isnumeric True
isdecimal False
isdigit False
>>> spam('³')
isnumeric True
isdecimal False
isdigit True
