The ConstainsRune checks if the Unicode code point is in the strings. contains.go package main import ( "fmt" "strings" ) func main() { msg := "a blue 🐋" r := '🐋' if strings.ContainsRune(msg, r) { fmt.Println("yes") } else { fmt.Println("no") } fmt.Println("---"...
如果只需要判断子字符串是否存在,可以使用strings.Contains。 编写代码示例来演示如何使用该函数或方法进行字符串查找: go package main import ( "fmt" "strings" ) func main() { str := "hello, Go language!" // 使用 strings.Index 查找子字符串 "Go" 的位置 index := strings.Index(str, "Go")...
The w2 string is a raw string and contains escape characters. They are printed rather than being interpreted. The sonnet55 is an example of a multiline strings in Go. $ go run raw_multi.go old falcon red fox fast dog lazy cat old falcon\tred fox\nfast dog\tlazy cat\n Not marble ...
r, size :=utf8.DecodeRuneInString(s[i:]) fmt.Printf("%d\t%c\n", i, r) i+=size } 每一次调用DecodeRuneInString函数都返回一个r和长度,r对应字符本身,长度对应r采用UTF8编码后的编码字节数目。实际上,Go语言的range循环在处理字符串的时候,会自动隐式解码UTF8字符串。 fori, r := range"Hell...
