在這段 golang 代碼中，我要求一個人輸入他的名字。輸入名稱后，數據將從values1變量中獲取，結果，它們將像這樣使用給定的鍵打印出來給定結果Enter your name: samenameHere is the name: samenameHere is the email address: email oneHere is the job role: job one我還想打印values2被注釋的變量的數據。同樣，如果我有值的數量，我是否必須一次又一次n地重復？for i := range values1要求的結果Enter your name: samenameHere is the name: samenameHere is the email address: email oneHere is the job role: job role oneHere is the name: samenameHere is the email address: email twoHere is the job role: job role two......代碼package mainimport "fmt"func main() { var name string keys := [3]string{"name", "email address", "job role"} values1 := [3]string{"samename", "email one", "job role one"} // values2 := [3]string{"samename", "email two", "job role two"} for { fmt.Printf("Enter your name: ") fmt.Scanln(&name) fmt.Println() if name == values1[0] { for i := range values1 { // j is index into keys j := i % len(keys) // Print blank line between groups. if j == 0 && i > 0 { fmt.Println() } fmt.Printf("Here is the %s: %s\n", keys[j], values1[i]) } break } else { fmt.Println("Name is not found. Try again!") } }}

如果您需要打印密鑰，也許您可以使用map. 你可以打印鍵和map值。
package main
import "fmt"
func main() {
var name string
value1 := map[string]string{"name": "samename", "email": "email one", "role": "job role one"}
value2 := map[string]string{"name": "samename", "email": "email two", "role": "job role two"}
values := []map[string]string{value1, value2}
var found bool
for {
fmt.Printf("Enter your name: ")
fmt.Scanln(&name)
fmt.Println()
for _, value := range values {
if value["name"] == name {
found = true
for k, v := range value {
fmt.Printf("Here is the %s: %s\n", k, v)
}
fmt.Println()
}
}
if found {
break
} else {
fmt.Println("Name is not found. Try again!")
}
}
}
