在Python中读入文件，并跳过文本文件的标题部分

如何解决在Python中读入文件，并跳过文本文件的标题部分

|| 我从gutenberg.org上取了一本文本格式的书，正在尝试阅读该文本，但是跳过了文件的开头部分，然后使用我编写的处理功能来解析其余部分。我怎样才能做到这一点？ 这是文本文件的开始。

和我当前处理整个文件的代码。

import string

def process_file(filename):
    \"\"\" opens a file and passes back a list of its words\"\"\"
    h = dict()
    fin = open(filename)
    for line in fin:
        process_line(line,h)
    return h

def process_line(line,h):
    line = line.replace(\'-\',\' \')

    for word in line.split():
        word = word.strip(string.punctuation + string.whitespace)
        word = word.lower()

        h[word] = h.get(word,0)+1

    

解决方法

添加此：

for line in fin:
   if \"START OF THIS PROJECT GUTENBERG BOOK\" in line:
       break

就在您自己的\“ for fin：\”循环中。     ,好吧，您只要阅读输入内容，直到符合条件即可跳过开头：

def process_file(filename):
    \"\"\" opens a file and passes back a list of its words\"\"\"
    h = dict()
    fin = open(filename)

    for line in fin:
        if line.rstrip() == \"*** START OF THIS PROJECT GUTENBERG EBOOK THE KAMA SUTRA OF VATSYAYANA ***\":
            break

    for line in fin:
        process_line(line,h)

    return h

请注意，在此示例中，我将ѭ4用作准则，但是您可以完全自己设置准则。
