使用Python 3中的编码打印到标准输出 [英] Printing to stdout with encoding in Python 3

问题描述

我有一个Python 3程序，该程序从Windows-1252编码的文件中读取一些字符串：

I have a Python 3 program that reads some strings from a Windows-1252 encoded file:

with open(file, 'r', encoding="cp1252") as file_with_strings:
    # save some strings

我以后要写到stdout。我试图做：

Which I later want to write to stdout. I've tried to do:

print(some_string)
# => UnicodeEncodeError: 'ascii' codec can't encode character '\xe9' in position 180: ordinal not in range(128)

print(some_string.decode("utf-8"))
# => AttributeError: 'str' object has no attribute 'decode'

sys.stdout.buffer.write(some_str)
# => TypeError: 'str' does not support the buffer interface

print(some_string.encode("cp1252").decode("utf-8"))
# => UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 180: invalid continuation byte

print(some_string.encode("cp1252"))
# => has the unfortunate result of printing b'<my string>' instead of just the string

I'我在这里挠头。我想打印从文件中获得的字符串，就像在cp1252中显示的一样。 （在我的终端中，当我执行更多$ file 时，这些字符显示为问号，因此我的终端可能是ascii。）

I'm scratching my head here. I'd like to print the string I got from the file just as it appears there, in cp1252. (In my terminal, when I do more $file, these characters appear as question marks, so my terminal is probably ascii.)

请澄清一下！谢谢！

推荐答案

使用cp1252编码时，必须使用相同的解码器。

When you encode with cp1252, you have to decode with the same.

例如：

import sys
txt = ("hi hello\n").encode("cp1252")
#print((txt).decode("cp1252"))
sys.stdout.buffer.write(txt)
sys.stdout.flush()

这将打印嗨 decodingn（在cp1252中编码）在解码后。

This will print "hi hello\n" (which was encoded in cp1252) after decoding it.
