单列表到字典

Question

我有这个清单:

single = ['key1', 'value1', 'key2', 'value2', 'key3', 'value3']

从这里创建字典的最佳方法是什么？

谢谢.

Answer 1

>>> single = ['key1', 'value1', 'key2', 'value2', 'key3', 'value3']
>>> dict(zip(single[::2], single[1::2]))
{'key3': 'value3', 'key2': 'value2', 'key1': 'value1'}

Answer 2

与SilentGhost的解决方案类似,无需构建临时列表:

>>> from itertools import izip
>>> single = ['key1', 'value1', 'key2', 'value2', 'key3', 'value3']
>>> si = iter(single)
>>> dict(izip(si, si))
{'key3': 'value3', 'key2': 'value2', 'key1': 'value1'}
