让我超越我的确切代码: 这是短模块
class SentenceSplitter:
def __init__(self, filename=None):
self._raw_text = self.raw_text(filename)
self._sentences = self.to_sentences()
def raw_text(self, filename):
text = ''
with open(filename, 'r') as file:
for line in file.readlines():
line = line.strip()
text += ''.join(line.replace(line, line+' '))
file.close()
text = text.strip() # Deal with the last whitespace
return text
def to_sentences(self):
""" Sentence boundaries occur at '.', '!', '?' except that,
there are some not-sentence boundaries that
may occur before/after the period.
"""
raw_text = self._raw_text
sentences = []
sentence = ''
boundary = None
for char in raw_text:
sentence += ''.join(char)
if char == '!' or char == '?':
sentences.append(sentence)
sentence = ''
""" The sign -> refers to 'followed by' """
elif char == '.':
i = raw_text.index(char) # slicing previous/following characters
boundary = True
if boundary:
sentences.append(sentence)
sentence = ''
return sentences
主要:
import textchange
ss = textchange.SentenceSplitter(filename='text.txt')
print(ss._sentences)
第一个if语句后的docstring
""" The sign -> refers to 'followed by' """
我评论了它,程序运行,否则没有。 elif语句中有更多代码,但在确定它仍然抛出错误后将其删除。这是追溯:
Traceback (most recent call last):

elif char == '.':

SyntaxError: invalid syntax
答案 0 :(得分:7)
文档字符串只是在函数的 start 中找到的字符串文字。他们仍然必须遵守缩进规则。
您的字符串未正确缩进elif
块;通过从if
块中删除之前,您完全结束了if
- elif
- else
块,并且允许<{1}} < / em>跟随。
使用常规正常评论,以elif
开头;包含仅注释的行不受缩进规则的限制:
#
或缩进字符串(它完全由Python作为代码执行,但是没有分配,因此再次丢弃):
if char == '!' or char == '?':
sentences.append(sentence)
sentence = ''
# The sign -> refers to 'followed by'
elif char == '.':
i = raw_text.index(char) # slicing previous/following characters
boundary = True
