读文件：

读取文件f = open('\info.txt')fil = f.read()f.close()

 按行读文件：

f = open("info.txt")while 1:   line = f.readline()   line=line.strip('\n') # 去掉换行符   if not line:       break   print line      f.close()

 

读取文件报错：

f1=open("fenci_result.txt",'r')

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 2892: invalid continuation byte

解决办法：

import codecs f1=codecs.open("fenci_result.txt",'r',encoding = "ISO-8859-1")
