将“Python 模板字符串”扩展为非 ASCII
[英]Extend “Python Template String” to Non-ASCII
问题描述
I'm trying to fill values in a formula string by using Python Template Strings .
我正在尝试使用Python Template Strings在公式字符串中填充值。 The formula sometimes contains identifiers having non-ASCII characters like α, ß, Γ etc. (see Unicode Greek and Coptic Chart ) .该公式有时包含具有非 ASCII 字符的标识符，如 α、ß、Γ 等（请参阅Unicode 希腊语和科普特图表） 。 But as per python documentation, the template string is limited to only ASCII identifiers.但根据 python 文档，模板字符串仅限于 ASCII 标识符。 The default regular expression to match the identifier is (?a:[_a-z][_a-z0-9]*) .匹配标识符的默认正则表达式是(?a:[_a-z][_a-z0-9]*) 。
How can I extend the default regular expression so it also matches the characters from Unicode Greek and Coptic Chart ?如何扩展默认正则表达式，使其也匹配来自Unicode Greek 和 Coptic Chart的字符？
