python小端模式讀寫txt

經嘗試，在windows下utf-16對應小端模式，utf-16-le不對應任何模式。

小端模式使用notapad++可以檢視生成檔案的模式,對應ucs-2 little endian編碼。

小端模式對應檔案頭 \ufeff.

# coding=utf-8

import os
import codecs
def check_charset(file_path):
import chardet
with open(file_path, "rb") as f:
data = f.read(4)
charset = chardet.detect(data)['encoding']
return charset
def readfile(path):
ofile = open(path, encoding='utf-8')
file_lineinfo = open("utf-16.txt", 'w', encoding='utf-16')
lines = ""
lines = ofile.readlines()
encoding = none
lst = 
if lines[0].startswith('\ufeff'):
for line in lines:
print(line)
if line.startswith('\ufeff'):
contents = line[1:]
else:
contents = line
file_lineinfo.writelines(contents)
file_lineinfo.close()
encoding = 'utf-16-le'
ofile.close()
import codecs
ofile = codecs.open(path, 'r', encoding)
lst = ofile.readlines()
ofile.stream.close()
else:
file_lineinfo.writelines('\n')
for line in lines:
print(line)
if line.startswith('\ufeff'):
contents = line[1:]
else:
contents = line
file_lineinfo.writelines(contents)
file_lineinfo.close()
def parsefile(filepath):
try:
linelist =   # 存放每一行的內容
with open(filepath, encoding=check_charset(filepath)) as fp:
line = fp.read()
print(line)
if line.startswith('\ufeff'):
encoding = 'utf-16-le'
fp2 = codecs.open(filepath, 'r', encoding)
linelist = fp2.readlines()
fp2.stream.close()
for i in linelist:  # 列印每一行
print(i)
except exception as ex:
print('[error]--', ex)
if __name__ == '__main__':
filepath = './test.txt'
parsefile(filepath)
readfile(filepath)
