Question

我意识到我可以使用ord和unichr内置的python函数来获取字符的unicode，反之亦然。但是，是否有一个ASCI字符集中所有可能字符的列表，我可以通过在python中调用函数或某些API来访问它？

换句话说，我可以通过某个函数调用访问此列表here?吗？

由于

Answer 1

底部的128个Unicode代码点是 ASCII所以，只要您将自己限制在0到127之间的序数值，unichr（或仅chr in Python 3）可以正常工作。

例如，以下Python 2.6.6程序（不可否认是旧式但我更喜欢那种教学形式）：

print " | 0 1 2 3 4 5 6 7 8 9 A B C D E F"
print "-+--------------------------------"

for row in range(2,8):
    s = "%d|"%(row)
    for col in range(0,16):
        if row != 7 or col != 15:                   # 7F is non-printable
            s = "%s %s"%(s,unichr(row * 16 + col))
    print s

为你输出ASCII表（好吧，无论如何都是可打印的位）：

 | 0 1 2 3 4 5 6 7 8 9 A B C D E F
-+--------------------------------
2|   ! " # $ % & ' ( ) * + , - . /
3| 0 1 2 3 4 5 6 7 8 9 : ; < = > ?
4| @ A B C D E F G H I J K L M N O
5| P Q R S T U V W X Y Z [ \ ] ^ _
6| ` a b c d e f g h i j k l m n o
7| p q r s t u v w x y z { | } ~

Answer 2

>>> from unicodedata import name, category
>>> for i in range(128):
    c = unichr(i)
    print hex(i), i, category(c), name(c, '--')

Answer 3

是否有ASCI字符集中所有可能字符的列表通过在python中调用函数或某些API进行访问？

没有没有内置支持，但你总是可以使用几个内置的支持

map(unichr, range(128))

如果使用Py3.X，因为unicode和非unicode之间没有区别，您需要使用chr。此外，map会返回map个对象，需要将其转换为list

list(map(chr, range(128)))

相反，如果您需要所有ascii字符的字符串，则可以加入结果列表

''.join(map(unichr, range(128)))

''.join(map(chr, range(128)))
