在Python中从数组中在线填充字典

Question

我需要从数组填充字典。我已经在三行中完成了，我尽量使它最短。有办法如何填充它在单行吗?

a = [['test',154],['test2',256]]
d = dict()
for b in a:
    d[b[0]] = b[1]

Answer 1

Just dict:)

>>> a = [['test',154],['test2',256]]
>>> dict(a)
{'test': 154, 'test2': 256}

Answer 2

你只做dict (a)或dict([[‘测试’,154年],[test2, 256]])。

Answer 3

L =[[‘测试’,154年],[test2, 256]]

在Python 3.x:

d = {k:v for k,v in L}

在Python 2.x:

d = dict([(k,v) for k,v in L])
