4.7.1 前綴和后綴
HasPrefix 判斷字符串 s 是否以 prefix 開頭：
strings.HasPrefix(s, prefix string) bool
HasSuffix 判斷字符串 s 是否以 suffix 結(jié)尾：
strings.HasSuffix(s, suffix string) bool
package main
import (
"fmt"
"strings"
)
func main() {
var str string = "This is an example of a string"
fmt.Printf("T/F? Does the string \"%s\" have prefix %s? ", str, "Th")
fmt.Printf("%t\n", strings.HasPrefix(str, "Th"))
}
輸出：
T/F? Does the string "This is an example of a string" have prefix Th? true
這個例子同樣演示了轉(zhuǎn)義字符 \ 和格式化字符串的使用。
字符串包含關(guān)系
Contains 判斷字符串 s 是否包含 substr ：
strings.Contains(s, substr string) bool
