Ansi to UTF-8 using python causing error
I tried the answer there to convert ansi to utf-8.
我在那里尝试了将 ansi 转换为 utf-8 的答案。
import io
with io.open(file_path_ansi, encoding='latin-1', errors='ignore') as source:
with open(file_path_utf8, mode='w', encoding='utf-8') as target:
shutil.copyfileobj(source, target)
But I got "TypeError: 'encoding' is an invalid keyword argument for this function"
但是我得到了“TypeError: 'encoding' is an invalid keyword argument for this function”
I tried with
我试过
with io.open(file_path_ansi, encoding='cp1252', errors='ignore') as source:
, too, and got same error.
，也得到了同样的错误。
Then I tried
然后我试过了
import io
with io.open(file_path_ansi, encoding='latin-1', errors='ignore') as source:
with io.open(file_path_utf8, mode='w', encoding='utf-8') as target:
shutil.copyfileobj(source, target)
and still got the same error. Also I tried with cp1252, too, but got the same error.
并且仍然出现相同的错误。我也尝试过 cp1252，但得到了同样的错误。
I learned from several stackoverflow questions that
我从几个stackoverflow问题中了解到
TypeError: 'encoding' is an invalid keyword argument for this function
is frequently arising error message in python 2.x
在python 2.x中经常出现错误信息
But mainly answerers were suggesting using python 3 in some way or the other.
但主要是回答者建议以某种方式使用 python 3。
Is it really impossible to convert ansi txt to utf-8 txt in python 2.x ? (I use 2.7)
在 python 2.x 中将 ansi txt 转换为 utf-8 txt 真的不可能吗？（我使用 2.7）
采纳答案by Rob?
For Python2.7, Use io.open()in both locations.
对于 Python2.7，io.open()在两个位置使用。
import io
import shutil
with io.open('/etc/passwd', encoding='latin-1', errors='ignore') as source:
with io.open('/tmp/goof', mode='w', encoding='utf-8') as target:
shutil.copyfileobj(source, target)
The above program runs without errors on my PC.
上述程序在我的 PC 上运行没有错误。

This is how you can convert ansi to utf-8 in Python 2 (you just use normal file objects):
这是在 Python 2 中将 ansi 转换为 utf-8 的方法（您只需使用普通文件对象）：
with open(file_path_ansi, "r") as source:
with open(file_path_utf8, "w") as target:
target.write(source.read().decode("latin1").encode("utf8"))

I had the same issue when I did try to write bytes to file. So my point is, bytes are already encoded. So when you use encoding keyword this leads to an error.
当我尝试将字节写入文件时，我遇到了同样的问题。所以我的观点是，字节已经被编码。因此，当您使用 encoding 关键字时，这会导致错误。

TypeError: 'encoding' is an invalid keyword argument for this function
类型错误：“编码”是此函数的无效关键字参数
open('textfile.txt', encoding='utf-16')
Use io, it will work in both 2.7 and 3.6 python version
使用 io，它将在 2.7 和 3.6 python 版本中工作
import io
io.open('textfile.txt', encoding='utf-16')
