Added a fixer that cleans up a tuple argument to isinstance after the tokens
in it were fixed. This is mainly used to remove double occurrences of
tokens as a leftover of the long -> int / unicode -> str conversion.

"""Fixer for has_key().
|
|
|
|
Calls to .has_key() methods are expressed in terms of the 'in'
|
|
operator:
|
|
|
|
d.has_key(k) -> k in d
|
|
|
|
CAVEATS:
|
|
1) While the primary target of this fixer is dict.has_key(), the
|
|
fixer will change any has_key() method call, regardless of its
|
|
class.
|
|
|
|
2) Cases like this will not be converted:
|
|
|
|
m = d.has_key
|
|
if m(k):
|
|
...
|
|
|
|
Only *calls* to has_key() are converted. While it is possible to
|
|
convert the above to something like
|
|
|
|
m = d.__contains__
|
|
if m(k):
|
|
...
|
|
|
|
this is currently not done.
