go - 相当于go中python的ord()、chr()？

Question

python的chr()相当于什么？和 ord() golang 中的函数？

chr(97) = 'a'
ord('a') = 97

Answer 1

它们被支持为简单的conversions :

ch := rune(97)
n := int('a')
fmt.Printf("char: %c\n", ch)
fmt.Printf("code: %d\n", n)

输出(在 Go Playground 上尝试):

char: a
code: 97

注意:您也可以转换 integer numeric value to a string它基本上将整数值解释为 UTF-8 编码值:

s := string(97)
fmt.Printf("text: %s\n", s) // Output: text: a

Converting a signed or unsigned integer value to a string type yields a string containing the UTF-8 representation of the integer. Values outside the range of valid Unicode code points are converted to "\uFFFD".
