python键值配对

Question

我有一个这样的数组arr1 = ['name','age','sex']，另一个数组的值类似于val1 = ['Jone','20','male']。现在我想做一个这样的dict-->；val = {'name':'jone','age':'20','sex':'male'}

现在我是这样做的-->

val = {}
val['name'] = val1[0]
val['age'] = val1[1]
val['sex'] = val1[2]

有更好的办法吗？在

Answer 1

>>> arr1 = ['name','age','sex']
>>> val1 = ['Jone','20','male']
>>> dict(zip(arr1, val1))
{'age': '20', 'name': 'Jone', 'sex': 'male'}

Answer 2

val = {}
for i in range(len(arr1)):
    val[arr1[i]] = val1[i]

Answer 3

在Python2.7以后的版本中，您可以使用字典理解

val = { k: v for k, v in zip(arr1, val1) }
