Looping through a dictionary for every other value

[fad3r]

Complete text of challenge:

1) Start with this list: ['a', 'b', 'c', ..., 'z'}
And create a function that turns it into this dictionary: {1: 'a', 2: 'b', 3: 'c', ..., 26: 'z'}

2) Start with this string: 'abc...z'
And create a function that turns it into this dictionary: {1: 'a', 2: 'b', 3: 'c', ..., 26: 'z'}

3) Take one of the above functions and include only the odd numbers / letters: {1: 'a', 3: 'c', ..., 25: 'y'}

Complete code for part 1 & 2 (part 3 is what i am trying to solve).

#Create list of letters
import string
letlist = list(string.ascii_lowercase)

#Create string of letters
letstring = string.ascii_lowercase

#Create list of numbers
list1=[]
for i in range (1, 27):
    list1.append(i)

#Create dictionary for part 1
def dictfunc():
    zipped =dict(zip(list1,letlist))

dictfunc()

#Create dictionary for part 2
def dictfun2():
    zipped2 = dict(zip(list1, letstring))

dictfun2()

If I don't use global I get an error about the dictionary not being found. My guess is somehow it is local in scope to the function that is why i tried using global.

Really appreciate all the help.

Adding this snippet

odd_entries = {k:v for k,v in zipped.items() if v % 2}
print (odd_entries)

Returns an error I've never seen before (good chance I screwed up something in the code above because some of it I didnt understand specically the k:v part.)
