如何从文本文件中仅获取标题名称 [英] How can I get only heading names.from the text file

问题描述

我有一个文本文件，如下所示:

I have a Text file as below:

Education: 

askdjbnakjfbuisbrkjsbvxcnbvfiuregifuksbkvjb.iasgiufdsegiyvskjdfbsldfgd

Technical skills : 
 java,j2ee etc.,

work done: 

oaugafiuadgkfjwgeuyrfvskjdfviysdvfhsdf,aviysdvwuyevfahjvshgcsvdfs,bvisdhvfhjsvjdfvshjdvhfjvxjhfvhjsdbvfkjsbdkfg

我只想提取标题名称，例如教育，技术技能等.

I would like to extract only the heading names such as Education,Technical Skills etc.

代码是:

with open("aks.txt") as infile, open("fffm",'w') as outfile:
    copy = False
    for line in infile:
        if line.strip() == "Technical Skills":
            copy =True
        elif line.strip() == "Workdone":
            copy = True


        elif line.strip() ==  "Education":
            copy = False
        elif copy:
            outfile.write(line)
        fh = open("fffm.txt", 'r')
        contents = fh.read()
        len(contents)

推荐答案

如果您确定标题名称位于冒号(:)之前，则可以编写正则表达式来搜索这种模式.

If you are sure that the title names occure before a colon (:) then you can write a regex to search for such a pattern.

    import re
    with open("aks.txt") as infile:
      for s in re.finditer(r'(?<=\n).*?(?=:)',infile.read()):
        print s.group()

输出将类似于

   Education
   Technical skills 
   work done
