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()


带bom头

def readWeibo():
    f = codecs.open(u'H:/数据/weibo/weibo.txt','r','utf-8')
    line = f.readline()
    if line[:3] == codecs.BOM_UTF8:
        line = line[3:]#去除bom头
    i=0
    while line:
        print line,
        line = f.readline()
        if i>10:
            break
    f.close()
    return

readWeibo()

显示行数的读取
 
  
def test_read():
    file_path = u"D:/dev_data/idf_data/weibo/weibo_text.txt"
    f = open(file_path, "r")
    for i,line in enumerate(f):
        print i,line,
        if i>10:
            break;
    f.close()
