我正在输入5个句子并需要使用多个分隔符进行拆分(,/!/?)
不幸的是,在编写代码时,我只考虑字母并放置这些分隔符并使用.split()。它工作得很好。
这是代码:
final_text = ''
split_one = ''
input_text = input("Enter the data: ")
count_d = input_text.count("!") + input_text.count("?") + input_text.count(".")
if count_d == 5:
final_text = input_text
final_text = final_text.replace('!', '! ').replace('?', '? ').replace('.', '. ')
split_one = final_text.split()
i = 0
while True:
print(split_one[i])
i += 1
if i == 5:
break
输入:a.b?c!d.f!
The output was
a.
b?
c!
d.
f!
但我实际上是在输入句子而不是字母。 E.g
hi.how are you? I am good! what about you?bye!
它给了我:
hi.
how
are
you?
I
而不是
hi.
how are you?
I am good!
what about you?
bye!
我可以做些什么来避免由于空格而导致的分割,并且仅针对分隔符进行分割? (,/。/!)

您可以使用itertools.groupby
按标点分割字符串,例如:
>>> import itertools as it
>>> s = 'hi.how are you? I am good! what about you?bye!'
>>> r = [''.join(v).strip() for k, v in it.groupby(s, lambda c: c in '.!?')]
>>> r
['hi', '.', 'how are you', '?', 'I am good', '!', 'what about you', '?', 'bye', '!']
>>> for sentence, punct in zip(*[iter(r)]*2):
... print(sentence + punct)
hi.
how are you?
I am good!
what about you?
bye!
如果您不关心标点符号,则可以使用:
>>> [''.join(v).strip() for k, v in it.groupby(s, lambda c: c in '.!?') if not k]
['hi', 'how are you', 'I am good', 'what about you', 'bye']
