python读入中文文本编码错误

python读入中文txt文本：

#coding:utf-8

def readFile():
    fp = open('emotion_dict//neg//neg_all_dict.txt','r')
    list = []
    for line in fp:
        list.append(line)
    fp.close()
    print(list)
readFile()

但是有时候会出现错误提示：

**UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 10: illegal multibyte sequence
**

此时，需要对代码做一个小的调整，就可以读入中文，即以中文二进制'rb'读入txt，然后转换为'utf-8'，具体代码如下：

#coding:utf-8

def readFile():
    fp = open('emotion_dict//neg//neg_all_dict.txt','rb')
    list = []
    for line in fp.readlines():
        line = line.strip()
        line = line.decode('utf-8')
        list.append(line)
    fp.close()
    print(list)
readFile()
