等价于python的ord（），chr（）吗？

Question

What is the equivalent of python's chr() and ord() functions in golang?

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

Answer 1

They are supported as simple conversions:

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

Output (try it on the Go Playground):

char: a
code: 97

Note: you can also convert an integer numeric value to a string which basically interprets the integer value as the UTF-8 encoded value:

s := string(97)
fmt.Printf("text: %s
", 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".
