You might try itertools.groupby
(https://docs.python.org/3/library/itertools.html#module-itertools).
text = """ word{vb}
wordtransl {vb}
sent1
sent1trans
sent2
sent2trans
"""
import itertools
import re
result_list = list()
lines = text.split("\n")
for line in lines[:]:
if line.startswith("sent"):
break
lines.pop(0)
def is_start(x):
pattern = re.compile(r"sent\d+$")
if re.search(pattern, x):
return True
for key, mygroup in itertools.groupby(lines, is_start):
result_list.append(list(mygroup))
print(result_list)
