除了字母字符、数字和下划线之外,Python 函数名称中是否还有其他允许的字符?如果是,它们是什么?
最佳答案
In Python 3 many characters are allowed :
identifier ::= xid_start xid_continue*
id_start ::= <all characters in general categories Lu, Ll, Lt, Lm, Lo, Nl,
the underscore, and characters with the Other_ID_Start property>
id_continue ::= <all characters in id_start, plus characters in the categories
Mn, Mc, Nd, Pc and others with the Other_ID_Continue property>
xid_start ::= <all characters in id_start whose NFKC normalization
is in "id_start xid_continue*">
xid_continue ::= <all characters in id_continue whose NFKC normalization
is in "id_continue*">
The Unicode category codes mentioned above stand for:
Lu - uppercase letters
Ll - lowercase letters
Lt - titlecase letters
Lm - modifier letters
Lo - other letters
Nl - letter numbers
Mn - nonspacing marks
Mc - spacing combining marks
Nd - decimal numbers
Pc - connector punctuations
Other_ID_Start - explicit list of characters in PropList.txt
to support backwards compatibility
Other_ID_Continue - likewise
每个角色的完整列表可以在 Unicode.org 上找到.
在 Python 2.x 中,它仅限于字母、数字和下划线。来自 the docs :
identifier ::= (letter|"_") (letter | digit | "_")*
letter ::= lowercase | uppercase
lowercase ::= "a"..."z"
uppercase ::= "A"..."Z"
digit ::= "0"..."9"
