最好采用 p法(0:0:1:1,2:2})
原标题:best way to create a dict like {0:0,1:1,2:2} using python

this is my code :

print dict(range(3),range(3))

但它显示的是错误:

Traceback (most recent call last):
  File "c.py", line 7, in <module>
    print dict(range(3),range(3))
TypeError: dict expected at most 1 arguments, got 2

可做些什么,

感谢

最佳回答

您可以使用一条在Avre 2.7或新娘中工作的字典:

{ i: i for i in range(3) }

或者说是老的沙里的话,你可以这样做:

dict((i, i) for i in range(3))
问题回答

工作

 dict(zip(range(3),range(3)))

更长但易于理解的方式:

d={}
for x in range(3):
    d[x]=x

print d
