在python 2.x中，'encoding是无效的关键字'错误是不可避免的吗？ [英] Is 'encoding is an invalid keyword' error inevitable in python 2.x?

问题描述

使用python导致错误的Ansi到UTF-8

我尝试了将ansi转换为utf-8的答案。

  
 with io.open（file_path_ansi，encoding ='latin-1'，errors ='ignore'）as source：
 with open（file_path_utf8，mode ='w' ，encoding ='utf-8'）作为目标：
 shutil.copyfileobj（来源，目标）
  

我尝试使用

$ b $ io.open（file_path_ansi，encoding ='cp1252'，errors ='ignore'）作为来源：

也有同样的错误。

然后我尝试了

  import io 
 
 with io.open（file_path_ansi，encoding ='latin-1'，errors ='ignore'）as source：
与io.open（file_path_utf8 ，mode ='w'，encoding ='utf-8'）作为目标：
 shutil.copyfileobj（源，目标）
  

仍然有相同的错误。我也试过cp1252，但也有同样的错误。

我从几个stackoverflow问题中学到了

  TypeError：'encoding '是这个函数的无效关键字参数
  

在python 2.x中经常出现错误消息

但主要是回答者建议使用python 3以某种方式或其他方式。

真的不可能转换ansi txt到utf-8 txt在python 2.x？ （我使用2.7）

解决方案

对于Python2.7，使用 io.open（）在两个地方。

  import io 
 import shutil 
 
 with io .open（'/ etc / passwd'，encoding ='latin-1'，errors ='ignore'）as source：
 with io.open（'/ tmp / goof'，mode ='w' ='utf-8'）作为目标：
 shutil.copyfileobj（来源，目标）
  

上述程序在我的电脑上运行没有错误。

Ansi to UTF-8 using python causing error

I tried the answer there to convert ansi to utf-8.

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"

I tried with

with io.open(file_path_ansi, encoding='cp1252', errors='ignore') as source:

, too, and got same error.

Then I tried

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.

I learned from several stackoverflow questions that

TypeError: 'encoding' is an invalid keyword argument for this function

is frequently arising error message in python 2.x

But mainly answerers were suggesting using python 3 in some way or the other.

Is it really impossible to convert ansi txt to utf-8 txt in python 2.x ? (I use 2.7)

解决方案

For Python2.7, Use io.open() in both locations.

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.
