我想在python中创建一个包含所有orr()的中文字符：

对于英语,相当于：

english = set(range(ord('a'),ord('z') + 1 ) +
              range(ord('A'),ord('Z') + 1 ))

解决方法:

从Unicode标准(v6.0,第12.1节),

Han ideographic characters are found in seven main blocks of the Unicode Standard, as shown in Table 12-2

Table 12-2. Blocks Containing Han Ideographs

Block                                   | Range       | Comment
----------------------------------------+-------------+-----------------------------------------------------
CJK Unified Ideographs                  | 4E00–9FFF   | Common
CJK Unified Ideographs Extension A      | 3400–4DBF   | Rare
CJK Unified Ideographs Extension B      | 20000–2A6DF | Rare, historic
CJK Unified Ideographs Extension C      | 2A700–2B73F | Rare, historic
CJK Unified Ideographs Extension D      | 2B740–2B81F | Uncommon, some in current use
CJK Compatibility Ideographs            | F900–FAFF   | Duplicates, unifiable variants, corporate characters
CJK Compatibility Ideographs Supplement | 2F800–2FA1F | Unifiable variants

除了这些块之外还有一些额外的东西：

Table 12-3. Small Extensions to the URO

Range     | Version | Comment
----------+---------+-------------------------------------------------
9FA6–9FB3 | 4.1     | Interoperability with HKSCS standard
9FB4–9FBB | 4.1     | Interoperability with GB 18030 standard
9FBC–9FC2 | 5.1     | Interoperability with commercial implementations
9FC3      | 5.1     | Correction of mistaken unification
9FC4–9FC6 | 5.2     | Interoperability with ARIB standard
9FC7–9FCB | 5.2     | Interoperability with HKSCS standard

要使用set操作构造一组这些的序数值,您可以这样做：

chinese = set(range(0x4E00, 0xA000) +
              range(0x3400, 0x4DC0) +
              range(0x20000, 0x2A6E0) +
              range(0x2A700, 0x2B740) +
              range(0x2B740, 0x2B820) +
              range(0xF900, 0xFB00) +
              range(0x2F800, 0x2FA20) +
              range(0x9FA6, 0x9FCC))

但请注意,此集包含超过75000个字符,因此它可能不是最紧凑或最有效的数据结构.

此外,如果您坚持在文字字符上使用ord(),则需要使用32位unicode文字形式：

>>> ord(u'\U00002F800')
