Making 2 lists into one dictionary

Question

is there a way to define a function that takes two lists and makes the elements in the first list the key and the elements in the second list the values of a dictionary?

names = ['ted','west','tom','jerry','fred'] and another list ages = [10,23,13,18,12] how can i define a function that takes the two lists and returns a dictionary with the names as the key and the scores as the value?

i know that i can turn each list into a dictionary and then append it but I'm not sure how i can place the colons.

The answer that was marked as duplicate will work for you. But you can also do something like this: `{k:v for k,v in zip(names, ages)}`. This would be how to place those "colons", but you can also call `dict` which works just as well. — Chrispresso, May 24 '16 at 19:14

zip them, followed by a dict comprehension

>>> ages = [10,23,13,18,12]

>>> names = ['ted','west','tom','jerry','fred']

>>> {x[0]:x[1] for x in zip(names, ages)}
{'ted': 10, 'tom': 13, 'fred': 12, 'jerry': 18, 'west': 23}

`dict(zip(names, ages))` works too ... comprehension not needed ... – mgilson May 24 '16 at 19:19
@mgilson cool, didn't know dict accepts collection of 2-tuples as args – Ayush May 24 '16 at 19:22
how can i store that new dictionary with a variable that i can call? – james2121 May 24 '16 at 19:26
like so nameAges = {x[0]:x[1] for x in zip(names, ages)} ? – james2121 May 24 '16 at 19:26
@james2121 yes.. also it's a best practise to use variable names like `name_ages` instead of `nameAges` in python – Ayush May 24 '16 at 19:28
