python键值配对

Question

我有一个这样的数组arr1 = ['name','age','sex']和另一个数组，其数值类似val1 = ['Jone','20','male']。现在我想制作一个看起来像这样的字典 - ＆gt; val = {'name':'jone','age':'20','sex':'male'}

目前我正在这样做dict - ＆gt;

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

有没有更好的方法呢？

Answer 1

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

Answer 2

使用python 2.7以后你可以使用字典理解

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

Answer 3

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