“None” is the default that’s used if isolation_level is not passed, and means
to do nothing. So just don’t pass it, there’s no need to pass “None”.

well if this were to be available in an .ini file, that’s not Python code in an
.ini file, it would have to be interpreted, such as:
sqlalchemy.connect_args = none
there’s a system by which these values are interpreted on a case-by-case basis
that’s stated in each dialect class, if the type is something other than
string. But this parameter isn’t part of that, since it’s just a string
type, and there’s no “None” handling. You’d just omit the argument to use the
default value.
