Python -从同一个.py文件中的所有变量创建列表

Question

所以我有下面这段类别的代码，有时我会通过添加一个新的类别来更新它，然后我必须手动地将这个类别添加到INITIAL_GOAL_CATEGORIES底部的列表中--如果每当我创建一个新的dict变量时，这个列表就会被自动更新的话，就会容易得多。有办法这样做吗？我导出INITIAL_GOAL_CATEGORIES变量并将其用于其他地方，因此如果我能够将变量名设置为所有其他变量的列表，那就太棒了。此文件将只包含类别的切块和底部的所有类别的列表。

categories.py

# Categories
ART = dict(name='Art', emoji='')
CULINARY = dict(name='Culinary', emoji='')
DIET = dict(name='Diet', emoji='')
DIY = dict(name='DIY', emoji='')
FINANCE = dict(name='Finance', emoji='')
FITNESS = dict(name='Fitness', emoji='')
GAMING = dict(name='Gaming', emoji='️')
MARTIAL_ARTS = dict(name='Martial Arts', emoji='')
MUSIC = dict(name='Music', emoji='')
RELATIONSHIP = dict(name='Relationship', emoji='')
SELF_CARE = dict(name='Self-Care', emoji='')
SELF_IMPROVEMENT = dict(name='Self-Improvement', emoji='✨')
STREAMING = dict(name='Streaming', emoji='⏺️')
TRAVEL = dict(name='Travel', emoji='✈️')
WEIGHT_TRAINING = dict(name='Weight Training', emoji='️')

INITIAL_GOAL_CATEGORIES = [ART, CULINARY, DIET, DIY, FITNESS, GAMING, MARTIAL_ARTS, MUSIC,
                           RELATIONSHIP, SELF_IMPROVEMENT, SELF_CARE, STREAMING, TRAVEL,
                           WEIGHT_TRAINING]

Answer 1

如果要创建一个列表，在添加此类全局值时更新其自身，请在这里说明您需要的内容：

# Categories
ART = dict(name='Art', emoji='')
CULINARY = dict(name='Culinary', emoji='')
DIET = dict(name='Diet', emoji='')
DIY = dict(name='DIY', emoji='')
FINANCE = dict(name='Finance', emoji='')
FITNESS = dict(name='Fitness', emoji='')
GAMING = dict(name='Gaming', emoji='️')
MARTIAL_ARTS = dict(name='Martial Arts', emoji='')
MUSIC = dict(name='Music', emoji='')
RELATIONSHIP = dict(name='Relationship', emoji='')
SELF_CARE = dict(name='Self-Care', emoji='')
SELF_IMPROVEMENT = dict(name='Self-Improvement', emoji='✨')
STREAMING = dict(name='Streaming', emoji='⏺️')
TRAVEL = dict(name='Travel', emoji='✈️')
WEIGHT_TRAINING = dict(name='Weight Training', emoji='️')

INITIAL_GOAL_CATEGORIES = [value for name, value in globals().items() if
                           name.isupper()]

这将遍历全局()中的所有值，并检查该值的名称是否大写。如果它符合标准，它就是一个类别，我们将它添加到类别列表中。

但正如评论中所说:字典更好：

# Categories
INITIAL_GOAL_CATEGORIES = {
    'Art': {'emoji': ''},
    'Culinary': {'emoji': ''},
    'Diet': {'emoji': ''},
    'DIY': {'emoji': ''},
    'Finance': {'emoji': ''},
    'Fitness': {'emoji': ''},
    'Gaming': {'emoji': '️'},
    'Martial Arts': {'emoji': ''},
    'Music': {'emoji': ''},
    'Relationship': {'emoji': ''},
    'Self-Care': {'emoji': ''},
    'Self-Improvement': {'emoji': '✨'},
    'Streaming': {'emoji': '⏺️'},
    'Travel': {'emoji': '✈️'},
    'Weight Training': {'emoji': '️'},
}
