2.1. uniseg.codepoint — Code Point

Unicode code point.

uniseg.codepoint.chr(cp: int, /) → str

Return the unicode object represents the code point integer cp

>>> chr(0x61) == 'a'
True
>>> chr(0x20b9f) == '\U00020b9f'
True

uniseg.codepoint.code_points(s: str, /) → Iterator[str]

Iterate every Unicode code points of the unicode string s

>>> s = 'hello'
>>> list(code_points(s)) == ['h', 'e', 'l', 'l', 'o']
True
>>> s = 'abc\U00020b9f\u3042'
>>> list(code_points(s)) == ['a', 'b', 'c', '\U00020b9f', '\u3042']
True

uniseg.codepoint.ord(c: str, index: int | None = None, /) → int

Return the integer value of the Unicode code point c

>>> ord('a')
97
>>> ord('\u3042')
12354
>>> ord('\U00020b9f')
134047
>>> ord('abc')
Traceback (most recent call last):
  ...
TypeError: need a single Unicode code point as parameter

It returns the result of built-in ord() when c is a single str object for compatibility:

>>> ord('a')
97

When index argument is specified (to not None), this function treats c as a Unicode string and returns integer value of code point at c[index] (or may be c[index:index+2]):

>>> ord('hello', 0)
104
>>> ord('hello', 1)
101
>>> ord('a\U00020b9f', 1)
