字典推导式在Python 2.6中无法工作。 - Ashwini Chaudhary

似乎OpenERP主干需要Python 2.7或更新版本。 - Martijn Pieters

Answer 1

在2.7版本中，字典推导 被加入了Python语言。

因此你需要升级到Python 2.7。如果你被困在2.6版本，你可以使用

groupby_dict = dict((gb['groupby'], gb) for gb in annotated_groupbys)

- Tim Pietzcker

Answer 2

你需要使用 dict 创建一个字典。

dict((gb['groupby'], gb) for gb in annotated_groupbys)

实际上，这是一个生成器表达式而不是列表推导式。 - Tim Pietzcker

删除了列表推导式 ;) - Nilesh
