[New-bugs-announce] [issue25131] The AST for dict and set displays has the lineno of the first value

[Claudiu Popa]

New submission from Claudiu Popa:

Hi,

In Python 3.5, the lineno for dict and set display ASTs is the line number of the first value, not the line number of the display character, as it was until 3.5. Here's an example:


  from ast import parse
  module = parse('''{
           '1':'2',
  }
  ''')
  dict_display = module.body[0].value
  print(dict_display.lineno)

I don't seem to find anything related to this in the documentation, but I presume this is a side effect of the new parser changes. It would nice to have this fixed or at least documented.
