Why don't you just store all the data you want into a dictionary and serialize
it with json or pickle?
import pickle
def write_data(data, path):
with open(path, 'w') as f:
pickle.dump(data, f)
def read_data(path):
with open(path, 'r') as f:
data = pickle.load(f)
return data
That way you end up with a python object and don't have to worry about string
parsing.

As an aside, to select every-n item in a list, list slices have a step
parameter. List slice notation is list[start:stop:step], so range(10)[::2] will
return every other item (0, 2, 4, 6, 8). range(10)[::3] will return every third
item (0, 3, 6, 9). And so on.
Also don't use str.split(theLine). Strings have a split method: theLine.split()
will do the same thing.
And File objects are iterators, so instead of doing:
for line in myFileObject.readlines():
you can just do:
for line myFileObject:
