list to map in python

Question

I have a list and I want to convert this list into map

mylist = ["a",1,"b",2,"c",3]

mylist is equivalent to

mylist = [Key,Value,Key,Value,Key,Value]

So Input:

mylist = ["a",1,"b",2,"c",3]

Output:

mymap = {"a":1,"b":2,"c":3}

P.S: I already have written following function that do same work, but I want to use iterator tools of python:

def fun():
    mylist = ["a",1,"b",2,"c",3]
    mymap={}
    count = 0
    for value in mylist:
        if not count%2:
            mymap[value] = mylist[count+1]
        count = count+1
    return mymap        

Answer 1

Using iter and dict-comprehension:

>>> mylist = ["a",1,"b",2,"c",3]
>>> it = iter(mylist)
>>> {k: next(it) for k in it}
{'a': 1, 'c': 3, 'b': 2}

Using zip and iter:

>>> dict(zip(*[iter(mylist)]*2)) #use `itertools.izip` if the list is huge.
{'a': 1, 'c': 3, 'b': 2}
