我坚持使用循环和字典值.
我有一个有28个键和一个列表列表的有序字典.该列表有18个元素,而每个子列表恰好有28个元素.
这些是字典键：
d.keys()
[u'ROWNO', u'crop_name', u'active', u'crop_id', u'root', u'FTR', u'FEP', u'FEI', u'FIESWP', u'FIESWI', u'PSI1', u'PSI2', u'PSI3', u'PSI4', u'BaseT', u'MiniCutT', u'C0', u'C1', u'C2', u'C3', u'BegRootD', u'MaxRootD', u'RootGC', u'NONIRR', u'IFALLOW', u'WPFSlope', u'WPFInt', u'CropPrice']
这是包含子列表的列表：

我想要做的是填写每个键值与子列表组合的字典值.
例如,第一个键：
d[u'ROWNO'] = [u'urban', u'field', u'agri', u'wood', u'urban', u'field', u'agri', u'wood', u'urban', u'field', u'agri', u'wood', u'urban', u'field', u'agri', u'wood', u'urban', u'field', u'agri']
我试过这个循环：
for id, k in enumerate(d.keys()):
for i in range(len(l)):
d[k] = l[i][id]
但它不起作用.
最佳答案 无需使用占位符值初始化字典,然后在之后填充值.
您可以在压缩密钥和值时从zip的返回值创建一个有序字典.
这是一个演示：
>>> from collections import OrderedDict
>>> keys = ['k1', 'k2']
>>> values = [['vA', 'vB'], ['vC', 'vD']]
>>> OrderedDict(zip(keys, values))
OrderedDict([('k1', ['vA', 'vB']), ('k2', ['vC', 'vD'])])
这种技术也适用于常规词典(当然,顺序将是任意的).
>>> dict(zip(keys,values))
{'k2': ['vC', 'vD'], 'k1': ['vA', 'vB']}
编辑响应评论：这应该做的伎俩,然后：
>>> OrderedDict(zip(keys, map(list, zip(*values))))
OrderedDict([('k1', ['vA', 'vC']), ('k2', ['vB', 'vD'])])
