Python list to text file and back to a list

I have a list from split() that look like this:

row[0] = ['one', 'two', 'three']
row[1] = ['three', 'four', 'five']

I write it to a text file and it looks like this:

['one', 'two', 'three']
['three', 'four', 'five']

And now I want to make a list again from my text file that would look like this:

row[0] = ['one', 'two', 'three']
row[1] = ['three', 'four', 'five']

How am I supposed to do that?

If you are just trying to serialize a list to disk for later use by a python program, I would suggest pickleing the list. Why reinvent the wheel when Python has serialization built in? 

import pickle

with open('outfile', 'wb') as fp:
    pickle.dump(row, fp)

To read it back:

with open ('outfile', 'rb') as fp:
    row = pickle.load(fp)

text = "['one', 'two', 'three']"
text = text[2:-2]
text_list = text.split("', '")

Hacky but gets the job done.

Also please reconsider why you want the text file to look like

['one', 'two', 'three']
