SyntaxError: unexpected EOF while parsing...for python 3.4 and nltk

Question

当我使用 python 3.4

在 Jupyter 中使用以下代码时出现解析错误

import nltk
from nltk.corpus import state_union
from nltk.tokenize import PunktSentenceTokenizer

train_text = state_union.raw("2005-GWBush.txt")
sample_text = state_union.raw("2006-GWBush.txt")

custom_sent_tokenizer = PunktSentenceTokenizer(train_text)

tokenized = custom_sent_tokenizer.tokenize(sample_text)

def process_content():
    try:
        for i in tokenized:
            words = nltk.word_tokenize(i)
            tagged = nltk.pos_tag(words)

            chunkGram = r"""Chunk: {<RB.?>*<VB.?>*<NNP><NN>?}"""

            chunkParser = nltk.RegexpParser(chunkGram)
            chunked = chunkParser.parse(tagged)

            print(chunked)

我收到以下错误：

 File "<ipython-input-12-a049462ffecb>", line 26

    ^
SyntaxError: unexpected EOF while parsing

请告诉我如何解决这个解析错误

Answer 1

Python 正在寻找 compound try: statement 的其余部分，例如finally: 或 except: 块。

由于您没有提供，Python 对此进行了投诉。由于没有其他块处于较低的缩进级别，它只能在解析器到达文件末尾时确定其余部分丢失了。因为解析器期望找到语句的另一部分，所以找到 EOF（文件结尾）是意外的。
