How to delete lines after the last \n\n\n\n?

text = """
zzzz zzz zzz zz zzzz zzz  z
zzzzz zzzzz zzzzzz zzzzz zzz



zzzzzzz zzzzzzzzz zz zzzzz zzzzz zzz
zzzzzzz zzz zz z z zz zzzz zzzzz z
zz zzzz zzzzzz zzzzzz zzzzzzz zzzz



zzzz zzzzzz zzzzz zzzzzz zzzzzz zzz
zzzzz zzzzzz zzzzzz zzzzzzzzz
zzzzzz zzzzzz zzzzz  zzzzzzz zzzzz zzzz
"""

Desired output is:

zzzz zzz zzz zz zzzz zzz  z
zzzzz zzzzz zzzzzz zzzzz zzz



zzzzzzz zzzzzzzzz zz zzzzz zzzzz zzz
zzzzzzz zzz zz z z zz zzzz zzzzz z

How about:

sep = "\n\n\n\n"
print(sep.join(text.split(sep)[:-1]))

Or, a more efficient solution, as suggested:

text.rsplit(sep, 1)[0]

As shown in the dup question, `text.rsplit(sep, 1)[0]` is cleaner and faster. – bereal Jul 02 '21 at 08:48
