How to convert for loop to list comprehension syntax in python?

Question

I have this code and I would like to write it in a list comprehension

list1 = ["A", "B", "C"]
list2 = [1, 2, 3]

my_dict = {}
y = 0
for x in list1:
    my_dict[x] = list2[y]
    y=y+1
print (my_dict)

Answer 1

You can use the dict constructor with a zip of the two lists instead:

my_dict = dict(zip(list1, list2))

Answer 2

Another solution :

my_dict={list1[i]:list2[i] for i in range(len(list1))}
