在文本文件中搜索关键字的第一次和最后一次出现之间的打印行python

我有一个文本文件，我想提取第一个和最后一个出现的短语之间包含“crypt”的行。我已经构建了下面的代码，但它只给出了包含“crypt”的行。在文本文件中搜索关键字的第一次和最后一次出现之间的打印行python

fr = open('D:\\mydata\\dataset\\ds\\rw\\f1.txt') 
fw = open('D:\\mydata\\dataset\\ds\\at\\f2.txt', 'w') 
line = fr.readline() 
while line: 
     ##print (line) 
    line = fr.readline() 
    ##fw.writelines(line) 
    if 'crypt' in line.lower(): 
     ##fw.close() 
     ##break 
     fw.writelines(line) 
    ##fw.close() 
fr.close()

有没有人有关于如何在python中做到这一点的想法。

以下是文本文件：

问题是问：“我从哪里开始”通常过于宽泛，也不好适合这个网站。人们有自己的方法来解决这个问题，正因为如此，没有一个正确的答案。请仔细阅读[**从哪里开始**]（// meta.programmers.stackexchange.com/questions/6366/where-to-start/6367#6367），然后解决您的文章。 – kayess

你的文件中没有单独的短语'crypt'，但是有'cryptainerleexe' – RomanPerekhrest

是的，我的意思是任何单词都包含“crypt”。 – Bander

您可以使用两种for loops到iterate通过线条和检查像地穴：

with open('file.txt', 'r') as f: 
    with open('file2.txt', 'w') as w: 
     data = f.readlines() 
     for i in xrange(len(data)): 
      if 'crypt' in data[i]: 
       for j in xrange(i+1, len(data)): 
        if 'crypt' in data[j]: 
         break 
        w.write(data[j])

，如果你想包括第一和最后之间的一切发生隐藏跳过之间的事件，您可以通过列表loop并保存第一次出现index然后loop通过反转该项目的和loop检查最后一次出现并保存index，然后第三loop写入数据：

with open('file.txt', 'r') as f: 
    with open('file2.txt', 'w') as w: 
     data = f.readlines() 
     start, end = 0, 0 
     for i in xrange(len(data)): 
      if 'crypt' in data[i]: 
       start = i 
       break 
     data2 = data[::-1] 
     for j in xrange(len(data2)): 
      if 'crypt' in data2[j]: 
       end = j 
       break 
     for t in range(start, len(data)-end): 
      w.write(data[t])

这给出了不包含隐窝的行。需要的是文件中“crypt”的第一次和最后一次出现之间的界限。 – Bander

@Bander所以你想忽略中间的出现，只是寻找第一个和最后一个？ –

+0

不，我想在中间包括所有内容，即第一个和最后一个“crypt”之间的所有内容。 @Moe A – Bander
