 1 package main
 2 
 3 import "fmt"
 4 import s"strings"
 5 
 6 var p = fmt.Println
 7 
 8 func main() {
 9     p("Contains: ",s.Contains("test","es"))
10     p("Count: ",s.Count("test","t"))
11     p("hasPrefix: ",s.HasPrefix("test","te"))
12     p("HasSuffix: ",s.HasSuffix("test","st"))
13     p("index: ",s.Index("test","e"))
14     p("Join; ",s.Join([]string{"a","b"},"-"))
15     p("Repeat: ",s.Repeat("a",5))
16     p("Replace: ",s.Replace("foo","o","0",-1))
17     p("Replace: ",s.Replace("foo","o","0",1))
18     p("Split: ",s.Split("a-b-c-d-e","-"))
19     p("ToLower: ",s.ToLower("TEST"))
20     p("ToUpper: ",s.ToUpper("test"))
21     p()
22 
23     p("Len: ",len("hello"))
24     p("Char: ","hello"[1])
25 }

显示如下

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]
