How to save a list to a file and read it as a list type?

Say I have the list score = [1,2,3,4,5] and it gets changed while my program is running. How could I save it to a file so that next time the program is run I can access the changed list as a list type?

I have tried:

score=[1,2,3,4,5]

with open("file.txt", 'w') as f:
    for s in score:
        f.write(str(s) + 'n')

with open("file.txt", 'r') as f:
    score = [line.rstrip('n') for line in f]


print(score)

But this results in the elements in the list being strings not integers.

Answer

I decided I didn’t want to use a pickle because I wanted to be able to open the text file and change its contents easily during testing. Therefore, I did this:

score = [1,2,3,4,5]

with open("file.txt", "w") as f:
    for s in score:
        f.write(str(s) +"n")

score = []
with open("file.txt", "r") as f:
  for line in f:
    score.append(int(line.strip()))

So the items in the file are read as integers, despite being stored to the file as strings.
