python读取文件乱码

方法一：使用codecs

import codecs

f = codecs.open('nlpir/Readme.txt','r','GBK')
line = f.readline()
while line:
    print line,
    line = f.readline()
f.close()

上面的方法很慢，可以直接读取整个文件

codecs.open('nlpir/Readme.txt','r','GBK').read()

还有这样读的readlines()

方法二：
#读取文档 
def read_file():
    path1='K:\SogouC.reduced\Reduced\C000008\10.txt'
    f = open(path1,'r+')
    file_list = f.read().decode("gbk")
    print file_list
    f.close()


#逐行读取文档 
def read_file_line():
    path1='K:\SogouC.reduced\Reduced\C000008\10.txt'
    f = open(path1,'r+')
    line = f.readline()
    while line:
        print line.decode('gbk')
        line = f.readline()
    f.close()
