通过转换unicode字符u'\ u20ac'

我正在尝试使用python打印货币符号。我可以通过规范化unicode字符来打印一些货币符号。由于在python 2.7中,在字符图中,我只能看到某些unicode字符的映射,而看不到'\ u20ac'的欧元符号。

要打印欧元符号,是否需要在字符映射图python文件中包含unicode字符?

或者还有其他方法可以用来印刷欧元符号吗?

我使用以下代码,但出现以下错误。

输出:

日元

¥

欧元

Traceback (most recent call last):
  File ".\new-test.py", line 8, in <module>
    print list1
  File "C:\Python27\lib\encodings\cp437.py", line 12, in encode
    return codecs.charmap_encode(input,errors,encoding_map)
UnicodeEncodeError: 'charmap' codec can't encode character u'\u20ac' in position 0: character maps to <undefined>

代码:

from __future__ import unicode_literals

import unicodedata

list  = ['Yen','\u00a5','Euro',u'\u20ac']

for character in list:    
        list1 = (unicodedata.normalize("NFKD", character)).strip()
        print list1

您的Windows命令提示符配置为使用代码页437(cp437),并且在该编码中未定义欧元符号。您可以将代码页更改为支持字符的1252:

C:\>py -2
Python 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:19:30) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> print u'\u20ac'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "D:\dev\Python27\lib\encodings\cp437.py", line 12, in encode
    return codecs.charmap_encode(input,errors,encoding_map)
UnicodeEncodeError: 'charmap' codec can't encode character u'\u20ac' in position 0: character maps to <undefined>
>>> ^Z

一个更好的选择是切换到Python 3.6或更高版本,该版本使用Windows Unicode API直接绕过编码问题直接写入控制台:

C:\>py -3
Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:59:51) [MSC v.1914 64 bit (AMD64)] on win32

>>> print('\u20ac')

您可以使用unichr()函数

print unichr(8364)
