标签: python unicode utf-8

当我想将utf-8转换为unicode时,我收到此错误,错误是:

Traceback (most recent call last):
  File "C:\Program Files (x86)\JetBrains\PyCharm Community Edition 2016.3.2\helpers\pydev\pydevd.py", line 1596, in <module>
    globals = debugger.run(setup['file'], None, None, is_module)

    view = changeListCode(train[1])
  File "C:/Users/Administrator/Desktop/new 1.py", line 33, in changeListCode
    a.append(i.decode('utf8'))
  File "C:\Anaconda2\lib\encodings\utf_8.py", line 16, in decode
    return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xcb in position 7: invalid continuation byte

我的代码是:

def readtrain():
    with open('Train.csv','rb')as csvfile:
        reader = csv.reader(csvfile)
        column1 = [row for row in reader]
    content_train = [i[1] for i in column1[1:]]
    view_train = [i[2] for i in column1[1:]]
    opinion_train = [i[3] for i in column1[1:]]
    print '训练集有 %s 条句子' % len(content_train)
    train = [content_train, view_train, opinion_train]
    return train

def changeListCode(b):
    a = []
    for i in b:
        a.append(i.decode('utf8'))
    return a




def segmentWord2(cont):
    c = []
    for i in cont:
        a = list(jieba.cut(i))
        c.append(a)
    return c


def transLabel(labels):
    for i in range(len(labels)):
        if labels[i] == 'pos':
            labels[i] = 2
        elif labels[i] == 'neu':
            labels[i] = 1
        elif labels[i] == 'neg':
            labels[i] = 0
        else: print "label无效:",labels[i]
    return labels


train = readtrain()

content = segmentWord2(train[0])  
view = changeListCode(train[1])
opinion = transLabel(train[2])

我将代码和文件复制到记事本++,它显示utf-8.i看到了其他问题,但我没有得到解决方案。我现在不能使用python 3.x。

我的文件是这样的:

我不知道如何上传我的文件。这是关于我的文件的截图,我的文件是csv。
