Please check the following:
[GCC 4.4.5 20100728 (prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import compiler
>>> compiler.parse( "d[1,] = None" )
Module(None, Stmt([Assign([Subscript(Name('d'), 'OP_ASSIGN', [Const(1)])], Name('None'))]))
>>> compiler.parse( "d[1] = None" )
Module(None, Stmt([Assign([Subscript(Name('d'), 'OP_ASSIGN', [Const(1)])], Name('None'))]))
>>> d = {}
>>> d[1,] = None
>>> d[1] = None
>>> d
{1: None, (1,): None}
As you can see d[1] = None and d[1,] = None do different things, but do they lead to the same abstract syntax tree. It's the same on Python 2.7:
Python 2.7.0+ (r27:82500, Aug 7 2010, 19:41:51)
[GCC 4.4.5 20100728 (prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import compiler
>>> compiler.parse( "d[1,] = None" )
Module(None, Stmt([Assign([Subscript(Name('d'), 'OP_ASSIGN', [Const(1)])], Name('None'))]))
>>> compiler.parse( "d[1] = None" )
Module(None, Stmt([Assign([Subscript(Name('d'), 'OP_ASSIGN', [Const(1)])], Name('None'))]))

Thank you for the report. I have added people found in Misc/maintainers.rst ot the nosy list, and also removed 2.6 since it’s in security mode and does not get bug fixes anymore. |

The compiler module is deprecated and essentially unmaintained. |
