如何从 Python 中的用户获取 Unicode 输入？

Question

这是代码： varUnicode = input('\tEnter your Unicode\n\t>') print('\u{}'.format(varUnicode)) 我想从用户那里获取 unicode 输入并打印字符。在上面的代码中 python 给我一个错误。

Answer 1

您需要在字符串前添加一个u以将其视为Unicode。 print(u'\u0420') 会给出 P.

Answer 2

\u 是在 string literals:

中识别的转义序列

Escape sequences only recognized in string literals are:
Escape      Meaning                                  Notes
Sequence

\N{name}    Character named name
            in the Unicode database                  (4)
\uxxxx      Character with 16-bit hex value xxxx     (5)
\Uxxxxxxxx  Character with 32-bit hex value xxxxxxxx (6)
Notes:

Changed in version 3.3: Support for name aliases 1 has been added.

Exactly four hex digits are required.

Any Unicode character can be encoded this way. Exactly eight hex digits are required.

使用

varUnicode = input('\tEnter your Unicode\n\t>')
print('\u{}'.format(varUnicode.zfill(4)).encode('raw_unicode_escape').decode('unicode_escape'))

或（也许更好）

varUnicode = input('\tEnter your Unicode\n\t>')
print('\U{}'.format(varUnicode.zfill(8)).encode('raw_unicode_escape').decode('unicode_escape'))
