I get:
>>> str.lower(str(), 'A')
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: lower() takes no arguments (1 given)
if you meant to write
>>> str.lower('A')
'a'
it's because "str" is the class that implements methods for the "str" type,
and, for an instance I of the class C:
I.method()
and
C.method(I)
are, in general, the same thing in Python
