R100	raise in except handler without from
R101	use bare raise in except handler
R102	unnecessary parentheses on raised exception

Examples

R100 raise in except handler without from

try:
    foo["bar"]
except KeyError:

except KeyError as e:
    raise MyException from e

R101 use bare raise in except handler

try:
    foo["bar"]
except KeyError as e:
    raise e

Will result in the error:

R101 Use bare raise in except handler.

To fix, change to:

try:
    foo['bar']
except KeyError:
    raise

R102 unnecessary parentheses on raised exception
