核心代码：

# -*- coding: utf-8 -*-'''python读取文件，每两行为一组'''def fenhang(infile,outfile): infopen = open(infile,'r',encoding='utf-8') outopen = open(outfile,'w',encoding='utf-8') lines = infopen.readlines() i = 1 for line in lines:  if i % 2 == 0:   outopen.write(line+'/n')  else:   outopen.write(line)  i += 1 infopen.close() outopen.close()fenhang("jb51.txt","o.txt")

通过执行 python jb51.txt

o.txt的内容
