Hii Mohammad Shireen One way is - dict(zip([1,2,3,4], [a,b,c,d])) If you have more keys than values, and you want to fill in values for the extra keys, you can use - itertools.izip_longest. Now see that If the lists are big you should use itertools.izip .. --- Example - i = iter(["a", "a", "b", "c", "b"]) j = iter([1,2,3,4,5]) k = list(zip(i, j)) for (x,y) in k: if x in d: d[x] = d[x] + y #or whatever your function needs to be to combine them else: d[x] = y

Use builtin zip function ``` keys = [1,2] values = ["a","b"] print(dict(zip(keys,values))) ``` https://realpython.com/JUMP_LINK__&&__python__&&__JUMP_LINK-zip-function/
