writing text file with line breaks

I want to write a text file where many lines are created, so I want to know how to put each value on a new line.

this is my code:

import itertools
from itertools import permutations , combinations
lista=[]

splits=itertools.permutations('0123456789', 5)
for x in splits:
    lista.append(x)

f=open('lala.txt', 'w')
for i in lista:
    f.write(str(i))

in this part I need to put the line break: f.write(str(i))

I have tried with: f.write(str(i)\n) but gives me an error
