因为我的cdv文件的编码是“ utf-8”，所以当我用excel打开它时，会导致失真，而当我将其转换为标准编码的“ ANSI”时，我得到了错误：

码：

import chardet

def convertEncoding(from_encode,to_encode,old_filepath,target_file):
    f1=file(old_filepath)
    content2=[]
    while True:
        line=f1.readline()
        content2.append(line.decode(from_encode).encode(to_encode))
        if len(line) ==0:
            break

    f1.close()
    f2=file(target_file,'w')
    f2.writelines(content2)
    f2.close()



convertFile = open('4321.csv','r')
data = convertFile.read()
print chardet.detect(data)
if chardet.detect(data)['encoding']=='utf-8':
    convertFile.close()
    convertEncoding(chardet.detect(data)['encoding'], "ansi", "4321.csv", "4321_bak.csv")

错误：

{'confidence': 0.99, 'encoding': 'utf-8'}

    content2.append(line.decode(from_encode).encode(to_encode))

感谢你的关心。
