You have to search the values. This
I am wondering how look for a key in a dictionary, given a value.
I have a dictionary similar to this:
a = { 'a1':1, 'a2':2, 'a3':3, 'a4'.:4}
If I have the value of 2, how would I look at the dictionary to turn
that into 'a2'.

just assume all the below code is correct.
I am not having a problem with it, it is all for example only.
I have a dictionary like this:
alpha = {'a':0,'b':0, ... 'z':0}
and the following code
f = file("hamlet.txt","r")
text = f.readlines()
f.close()
for line in text:
for char in line:

Indeed, dictionaries don't have a .key attribute.
Instead, use:
# Get list of values for 'key1'
aList = dol[ 'key1' ]
This would return the list of values you have assigned to 'key1' in
the dictionary. Once you got that list, you can look in the list to
find out the index of 'lil1' and return i
I am trying to discover the syntax for call on a dictionary of lists by
key and index.
The data structure looks like this:
dol = {'key1':['li1','li2','li3'],'key2':['li1','li2','li3'],\
'key3':['li1'li2,'li3','']}
The keys are passed to a function as arguments, and I want the value of
