python指定分隔符来分割文件

1 import re
2 p = re.compile('AAAAAAAA',re.S)
3 f = open(r"D:	estoldfile.txt","r").read()
4 paralist = p.split(f)
5 total_num = len(paralist)
6 for paraindex in range(total_num):
7     filewrite=file( r"D:	est\" + str(paraindex) + ".txt",'w')
8     filewrite.writelines(paralist[paraindex])
9 filewrite.close()
