Use itertools.islice()
to pick a certain range of lines:
from itertools import islice
with open ('kafka_hungerkuenstler.txt', encoding = 'utf-8') as f:
for line in islice(f, 47, 392):
The loop will only iterate over lines 47 (counting from zero) until 391, inclusive; counting from 1 that's line 48 through to 392, inclusive.
