标准库的 |
|
package main
|
|
import s "strings"
import "fmt"
|
|
我们给 |
var p = fmt.Println
|
func main() {
|
|
这是一些 |
p("Contains: ", s.Contains("test", "es"))
p("Count: ", s.Count("test", "t"))
p("HasPrefix: ", s.HasPrefix("test", "te"))
p("HasSuffix: ", s.HasSuffix("test", "st"))
p("Index: ", s.Index("test", "e"))
p("Join: ", s.Join([]string{"a", "b"}, "-"))
p("Repeat: ", s.Repeat("a", 5))
p("Replace: ", s.Replace("foo", "o", "0", -1))
p("Replace: ", s.Replace("foo", "o", "0", 1))
p("Split: ", s.Split("a-b-c-d-e", "-"))
p("ToLower: ", s.ToLower("TEST"))
p("ToUpper: ", s.ToUpper("test"))
p()
|
你可以在 |
|
虽然不是 |
p("Len: ", len("hello"))
p("Char:", "hello"[1])
}
|
$ go run string-functions.go
Contains: true
Count: 2
HasPrefix: true
HasSuffix: true
Index: 1
Join: a-b
Repeat: aaaaa
Replace: f00
Replace: f0o
Split: [a b c d e]
toLower: test
ToUpper: TEST

Len: 5
Char: 101
