How to create a dictionary using 2 lists?

[Harsh Hajela]

I've 2 lists say:

list1 = ['a','b','c']
list2 = [1,2,3]

and i want a dictionary as an output:

dict1 = {'a':1,'b':2,'c':3}

How to achieve this using Built in Functions?

[Frinavale]

Why not just loop through each list and set the dictionary values?

For example:
(pseudo code)

Loop through List1 and List2
  For this iteration get the Key from List1
  For this iteration get the Value from List2
  Add an item to the dictionary at the Key with the Value for this iteration
Increment the iteration and go back to the start of the loop

Thanks mate for your reply..

i was looking for some built in function.. i faced an interview today and i was clueless when they asked me to use built in functions of python..

>>> dict(zip(['a','b','c'], [1,2,3]))
{'a': 1, 'c': 3, 'b': 2}
>>>
