julia - 你如何在 Julia 中找到一个字符的 unicode 值？

Question

我正在寻找类似 Python 的 ord(char)对于 Julia 返回一个整数。

Answer 1

我认为您正在寻找 codepoint .从文档:

codepoint(c::AbstractChar) -> Integer

Return the Unicode codepoint (an unsigned integer) corresponding to the character c (or throw an exception if c does not represent a valid character). For Char, this is a UInt32 value, but AbstractChar types that represent only a subset of Unicode may return a different-sized integer (e.g. UInt8).

例如:

julia> codepoint('a')
0x00000061

获得完全等同于 Python 的 ord函数，您可能希望将结果转换为有符号整数:

julia> Int(codepoint('a'))
97
