Question

我正在尝试解决一个需要清除文本（以摆脱所有标点和空格）并将其保存到同一寄存器的问题。

with open("moby_01.txt") as infile, open("moby_01_clean_3.txt", "w") as outfile:
    for line in infile:
        line.lower
        ...
        cleaned_words = line.split("-")
        cleaned_words = "\n".join(cleaned_words)
        cleaned_words = line.strip().split() 
        cleaned_words = "\n".join(cleaned_words)
        outfile.write(cleaned_words)

我希望程序的输出是单词列表，因为它们在文本中但在一行中是一个。但是事实证明，在for循环中，只有最后三行会发生迭代，并且如果标点符号为单词，则输出为列表：

Call

Ishmael.
Some

precisely--having

Answer 1

您可能想要更改此设置。您在这里再次使用line。

cleaned_words = line.strip().split()

到

cleaned_words = cleaned_words.strip().split()

Answer 2

我终于找到了解决这个问题的方法。练习书（快速Python书。第三版。NaomiCeder），Python文档和StackOverflow帮助了我。

with open("moby_01.txt") as infile, open("moby_01_clean.txt","w") as outfile:
    for line in infile:
        cleaned_line = line.lower()
        cleaned_line = cleaned_line.translate(str.maketrans("-", " ", ".,?!;:'\"\n"))
        words = cleaned_line.split()
        cleaned_words = "\n".join(words)
        outfile.write(cleaned_words + "\n")

我将-中的关键字参数z的{{1}}符号移到了str.maketrns(x[,y[,z]])，因为其他一些带有x的单词仍然串联在文件中。出于同样的原因，我在--

中添加了\n

.split（）序列最多只能使用一次
