阅读文件并跳过Python中文本文件的标题部分

我从gutenberg.org以文本格式拍摄了一本书，并且正在尝试阅读文本，但是跳过文件的开始部分，然后使用我编写的过程函数来解析其余部分。我怎样才能做到这一点？阅读文件并跳过Python中文本文件的标题部分

这是文本文件的开始。

和我的代码，当前处理整个文件。

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

不要忘记关闭文件。您可能想要使用'with'关键字。也就是'open（filename）as fin：'当你退出with context时，上下文管理器会为你关闭这个文件。和upvoted nightcraker的答案。 – 2011-04-13 19:51:18

补充一点：

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

之前你自己 “在鳍线：” 循环。

好了，你可以只读取输入，直到你符合你的标准来跳过开头：

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，我在这个例子中使用line.rstrip() == "*** START OF THIS PROJECT GUTENBERG EBOOK THE KAMA SUTRA OF VATSYAYANA ***"作为一个严格的标准，但你可以完全正常的自行设置。
