[英]Convert list of lists to list of dictionaries
I want to convert a list of lists to a list of dictionaries.我想将列表列表转换为字典列表。 I have a way to do it but I suspect there's a better way:
我有办法做到这一点,但我怀疑有更好的方法:
t = [[1,2,3], [4,5,6]]
keys = ['a', 'b', 'c']
[{keys[0]:l[0], keys[1]:l[1], keys[2]:l[2]} for l in t]
with output带输出
[{'a': 1, 'c': 3, 'b': 2}, {'a': 4, 'c': 6, 'b': 5}]
This could be done with a loop, but I bet there's a function to do it even easier.这可以通过循环来完成,但我敢打赌有一个函数可以更容易地做到这一点。 From this answer I'm guessing there's a way to do it with the
map
command, but I'm not quite sure how.从这个答案我猜有一种方法可以使用
map
命令来做到这一点,但我不太确定如何。
It can also be solved with a dictionary comprehension, this way:它也可以通过字典理解来解决,这样:
>>> [{k:v for k,v in zip(keys, l)} for l in t]
[{'c': 3, 'b': 2, 'a': 1}, {'c': 6, 'b': 5, 'a': 4}]
