AttributeError: 'dict' object has no attribute 'bytes'
wtf....why __builtins__ is dict?

wtf....why __builtins__ is dict?

https://docs.python.org/2/reference/executionmodel.html

CPython implementation detail: Users should not touch __builtins__; it is strictly an implementation detail. Users wanting to override values in the builtins namespace should import the __builtin__ (no ‘s’) module and modify its attributes appropriately.

I agree that we need a fix, but then we should use __builtin__/builtins module.

thanks~ @Kojoley

By default, when in the main module, builtins is the built-in module builtin (note: no ‘s’); when in any other module, builtins is an alias for the dictionary of the builtin module itself. builtins can be set to a user-created dictionary to create a weak form of restricted execution.

looks like __main__ module or other module have diffence __builtins__ and type,I'll close this PR

This should probably be

from six.moves import builtins
bytes = builtins.bytes

(feel free to re-close this if you want to make a separate PR).

Fixed by #7272
