Updating a dictionary from list

Question

How can i update a dictionary with keys from a list dict_keys and values from a list dict_values? I have tried using for loop in this way:

for i in dict dict_keys:
    for o in dict_values:
        dict(i) = o

You can create a dictionary using a dictionary comprehension. The zip function creates an iterator that will return a set with one item from each list, just like a zipper joins two sides of teeth. You can then combine one key and one value k:v for each corresponding pair.

dict = {k:v for k, v in zip(dict_keys, dict_values)}

If you already have a dict and you just want to update it with these values, simply call the update() function on it with the same comprehension:

dict.update({k:v for k, v in zip(dict_keys, dict_values)})
