Rename Method refactoring allows you to rename a method to a name with an 'internal use' indicator

[researcher175]

Rename Method refactoring allows the use of the name of an 'internal field' to rename a public method. According to PEP 8, special formats starting with underscores are recognized as 'internal use' indicators, and import formats ignore those names This can cause errors related to undefined attributes or incompatible types. It would be nice if Rope sent an alert to users in this operation type

1. Steps to reproduce the behavior:

   
   import csv
   from collections import OrderedDict

DEFAULT_ENCODING = 'utf-8'

class BaseFormat(object): def init(self, fp, **kwargs): pass

def to_iterable(self):
    raise NotImplementedError('Must implement a "to_iterable" method.')

@classmethod
def detect(cls, stream):
    raise NotImplementedError('Must implement a "detect" class method.')

class CSV(BaseFormat): delimiter = ","

def __init__(self, fp, **kwargs):
    BaseFormat.__init__(self, fp, **kwargs)
    reader = csv.reader(fp, delimiter=self.delimiter)
    self.data = [row for row in reader]

def to_iterable(self):
    return self.data

@classmethod
def detect(cls, stream):
    return False

_registry = OrderedDict([ ('csv', CSV), ])

def detect(fp, max_read=1024): for Format in _registry.values(): if Format.detect(fp.read(max_read)): return Format return None

def get_registry(): return _registry

def register(name, format_class): get_registry()[name] = format_class

2. Apply the Rename Method refactoring with the new name '_registry' to the method 'get_registry'
