转换任务为di

Question

我有很多作业要打：

definition = ['basename', 'dirname', 'supports_unicode_filenames']
condition = ['isabs', 'isdir', 'isfile', 'islink', 'ismount']
.
.
.

打算将它们转换为dict，避免重复键入：

{'definition': ['basename', 'dirname', 'supports_unicode_filenames'],
 'condition': ['isabs', 'isdir', 'isfile', 'islink', 'ismount'] ...}

我试着在课堂上把它们封装起来。你知道吗

class OsPath:
    definition = ['basename', 'dirname', 'supports_unicode_filenames']
    condition = ['isabs', 'isdir', 'isfile', 'islink', 'ismount']

操作控制台

In [125]: dt = dict(vars(OsPath))
In [127]: {i:dt[i] for i in dt if not i.startswith('__')}
Out[127]:
{'condition': ['isabs', 'isdir', 'isfile', 'islink', 'ismount'],
 'definition': ['basename', 'dirname', 'supports_unicode_filenames']}

怎么用捷径？你知道吗

Answer 1

你可以做：

definition = ['basename', 'dirname', 'supports_unicode_filenames']
condition = ['isabs', 'isdir', 'isfile', 'islink', 'ismount']
d = {'definition': definition, 'condition': condition }

注意，应该避免使用变量名dict，它是一个内置对象。你知道吗

但老实说，如果你是大规模地这样做的话，你所尝试的并不是好的做法。你应该重新考虑你的物品的设计。你知道吗

Answer 2

这是你想要的吗：

definition = ['basename', 'dirname', 'supports_unicode_filenames']
condition = ['isabs', 'isdir', 'isfile', 'islink', 'ismount']

result = {i: globals()[i] for i in ['definition', 'condition']}

Answer 3

使用SimpleNamespace

from types import SimpleNamespace
sn = SimpleNamespace(
definition = ['basename', 'dirname', 'supports_unicode_filenames'],
condition = ['isabs', 'isdir', 'isfile', 'islink', 'ismount'],
)

它输出：

In [44]: sn
Out[44]: namespace(condition=['isabs', 'isdir', 'isfile', 'islink', 'ismount'], definition=['basename', 'dirname', 'supports_unicode_filenames'])

In [45]: vars(sn)
Out[45]:
{'condition': ['isabs', 'isdir', 'isfile', 'islink', 'ismount'],
 'definition': ['basename', 'dirname', 'supports_unicode_filenames']}

In [17]: dict(definition = ['basename', 'dirname', 'supports_unicode_filenames'],condition = ['isabs', 'isdir'
    ...: , 'isfile', 'islink', 'ismount'])
Out[17]: 
{'definition': ['basename', 'dirname', 'supports_unicode_filenames'],
 'condition': ['isabs', 'isdir', 'isfile', 'islink', 'ismount']}
