python实现根据文件关键字进行切分为多个文件的示例

#!/usr/bin/env python#__*__ coding: utf-8 __*__import reimport linecache def fileParse(): inputfile = input('Input SourcFile:') ##输入源文件，如A.txt fp = open(inputfile, 'r')  number =[] lineNumber = 1 keyword = input('Slice Keyword:') ##输入你要切分的关键字 outfilename = input('Outfilename:')##输出文件名，如out.txt则写out即可，后续输出的文件是out0.txt,out1.txt...  for eachLine in fp:    m = re.search(keyword, eachLine) ##查询关键字  if m is not None:   number.append(lineNumber) #将关键字的行号记录在number中  lineNumber = lineNumber + 1 size = int(len(number)) for i in range(0,size-1):  start = number[i]  end = number[i+1]  destLines = linecache.getlines(inputfile)[start+1:end-1] #将行号为start+1到end-1的文件内容截取出来  fp_w = open(outfilename + str(i)+'.txt','w') #将截取出的内容保存在输出文件中  for key in destLines:   fp_w.write(key)  fp_w.close() if __name__ == "__main__": fileParse()
