如何通过使用列表的索引作为键和列表的项作为值来将列表添加到字典？

Question

Question: Given a list named list1 and a dictionary named dict1 , using "For" loop to write code to add all items of list1 to dict1 by using the index of the list as the key of the dictionary and the item of the list as the value of the dictionary. for example:

`    list1 = ["a","b","c"]`

`    dict1 = {7:"d",8:"e",9:"f"}`

after running your code, dict1 = {7:"d",8:"e",9:"f",0:"a",1:"b",2:"c"}

My Code:

`dict1 = {7:"d", 8:"e", 9:"f"}
list1 = ["a", "b", "c"]
ii = 0
for i in [dict1]:
    dict1[ii] = list1[ii]
    ii = ii + 1
    print(dict1)`

2nd attempt after 1 desperate hour of trying:

`for i in list1:
    if i not in dict1.keys():
        dict1[0] = list1[0]
        dict1[1] = list1[1]
        dict1[2] = list1[2] 
        print(dict1)`

I'm lost!

Answer 1

Do like this,

>>> list1 = ["a","b","c"]
>>> dict1 = {7:"d",8:"e",9:"f"}
>>> dict1.update(dict(enumerate(list1)))
>>> dict1
{0: 'a', 1: 'b', 2: 'c', 7: 'd', 8: 'e', 9: 'f'}

or

>>> dict(dict1.items() + list(enumerate(list1)))
{0: 'a', 1: 'b', 2: 'c', 7: 'd', 8: 'e', 9: 'f'}
