python Convert Encoding:LookupError: unknown encoding: ansi
提问by BruceZhong
Because of my encode of cdv file is "utf-8",so when I open it with excel it will cause distortion,and when I convert it to then standard encode "ANSI",I get the error:
由于我的cdv文件的编码是“utf-8”，所以当我用excel打开它时会导致失真，当我将其转换为标准编码“ANSI”时，出现错误：
code:
代码：
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")
error:

There's no ansiencoding in Python Standard Encodings.
ansiPython Standard Encodings 中没有编码。
Choose appropriate encodings from following link: Standard Encodings
从以下链接中选择适当的编码：标准编码
