以下是引用wass99在2020-11-15 23:40:25的发言： 如题，以下简单代码基本实现了在txt1.txt文本中查找关键字（关键字保存的文档keywords.txt），然后保存有关键字那行的内容到result.txt中，现在只能保存一行内容，请问如何能够实现保存关键字上下三行的内容到result.txt中？ 烦请指教，非常感谢！！ with open(r'd:\test\keywords.txt', 'r') as f1, open('d:\test\txt1.txt', 'r') as f2, open('d:\test\result.txt', 'w') as f3: for i in f1: keyword = i.strip('\n') f2.seek(0) for line in f2: if keyword in line: f3.write(line + '\n')  程序代码：data=["","",""] keywords={} with open(r'keywords.txt', 'r') as f1, open('txt1.txt', 'r') as f2, open('result.txt', 'w') as f3: #先处理keywords.txt,存入keywords字典里 for i in f1: keyword = i.strip('\n') data[0]=data[1] data[1]=data[2] data[2]=keyword keywords[data[1]]=' '.join(data) keywords[data[2]]=data[1]+' '+data[2]+' '+''#如果是keywords.txt的最后一行在keywords里也能有值 for line in f2: if line in keywords: f3.write(keywords[line] + '\n') |
