我想把这些结合起来:

keys = ['name', 'age', 'food']
values = ['Monty', 42, 'spam']

在单个词典中:

{'name': 'Monty', 'age': 42, 'food': 'spam'}

最佳解决方案仍然是:

In [92]: keys = ('name', 'age', 'food')
...: values = ('Monty', 42, 'spam')
...: 

In [93]: dt = dict(zip(keys, values))
In [94]: dt
Out[94]: {'age': 42, 'food': 'spam', 'name': 'Monty'}

转换它:

    lst = [('name', 'Monty'), ('age', 42), ('food', 'spam')]
    keys, values = zip(*lst)
    In [101]: keys
    Out[101]: ('name', 'age', 'food')
    In [102]: values
    Out[102]: ('Monty', 42, 'spam')

其他回答

这样地:

keys = ['a', 'b', 'c']
values = [1, 2, 3]
dictionary = dict(zip(keys, values))
print(dictionary) # {'a': 1, 'b': 2, 'c': 3}

Voila:-)成对dict构造函数和zip函数非常有用。

更自然的方法是使用词典理解

keys = ('name', 'age', 'food')
values = ('Monty', 42, 'spam')    
dict = {keys[i]: values[i] for i in range(len(keys))}

所有答案总结如下:

l = [1, 5, 8, 9]
ll = [3, 7, 10, 11]

zip:

dict(zip(l,ll)) # {1: 3, 5: 7, 8: 10, 9: 11}

#if you want to play with key or value @recommended

{k:v*10 for k, v in zip(l, ll)} #{1: 30, 5: 70, 8: 100, 9: 110}

计数器:

d = {}
c=0
for k in l:
    d[k] = ll[c] #setting up keys from the second list values
    c += 1
print(d)
{1: 3, 5: 7, 8: 10, 9: 11}

枚举:

d = {}
for i,k in enumerate(l):
    d[k] = ll[i]
print(d)
{1: 3, 5: 7, 8: 10, 9: 11}
keys = ('name', 'age', 'food')
values = ('Monty', 42, 'spam')
out = dict(zip(keys, values))

输出:

{'food': 'spam', 'age': 42, 'name': 'Monty'}

试试看:

>>> import itertools
>>> keys = ('name', 'age', 'food')
>>> values = ('Monty', 42, 'spam')
>>> adict = dict(itertools.izip(keys,values))
>>> adict
{'food': 'spam', 'age': 42, 'name': 'Monty'}

在Python2中,与zip相比,它的内存消耗也更经济。
