Question

I need to go through a text file with strings separated by a space. I would like to have this code be able to read each word and count the number of recurring letters in each word. For example apple would have an output of :
apple
a 1
p 2
l 1
e 1
however, when i run this code I am getting the output of 1's for each word. 

s = 'apple'
for line in s:

    keys = []  # list to save characters

    line = line.strip()  # trim spaces from beginning and end

    words = line.split()  # split line by space

    for word in words:  # for every word in words

        keys = keys + list(word)  # get the characters

    character_dict = set(keys)  # A set to store non redundant

    for key in character_dict:
        print("%s\t%d" % (key, keys.count(key)))

Answer 1

line = 'apple'
keys = []
for x in line:
    keys.append(x)
d = dict()
for y in keys:
    if (not y in d.keys()):
        d[y] = 1
    else:
        d[y] += 1
for z in d.keys():
    print(z,d[z])
