如何在Go中同时写入两个不同的csv文件？

import (
    "encoding/csv"
    "os"
)

file1, err := os.Create("file1.csv")
if err != nil {
    panic(err)
}
defer file1.Close()

file2, err := os.Create("file2.csv")
if err != nil {
    panic(err)
}
defer file2.Close()

writer1 := csv.NewWriter(file1)
defer writer1.Flush()

writer2 := csv.NewWriter(file2)
defer writer2.Flush()

data1 := [][]string{
    {"1", "John", "Doe"},
    {"2", "Jane", "Smith"},
}

data2 := [][]string{
    {"A", "Apple"},
    {"B", "Banana"},
}

for _, row := range data1 {
    err := writer1.Write(row)
    if err != nil {
        panic(err)
    }
}

for _, row := range data2 {
    err := writer2.Write(row)
    if err != nil {
        panic(err)
    }
}

writer1.Flush()
writer2.Flush()

package main

import (
    "encoding/csv"
    "os"
)

func main() {
    file1, err := os.Create("file1.csv")
    if err != nil {
        panic(err)
    }
    defer file1.Close()

    file2, err := os.Create("file2.csv")
    if err != nil {
        panic(err)
    }
    defer file2.Close()

    writer1 := csv.NewWriter(file1)
    defer writer1.Flush()

    writer2 := csv.NewWriter(file2)
    defer writer2.Flush()

    data1 := [][]string{
        {"1", "John", "Doe"},
        {"2", "Jane", "Smith"},
    }

    data2 := [][]string{
        {"A", "Apple"},
        {"B", "Banana"},
    }

    for _, row := range data1 {
        err := writer1.Write(row)
        if err != nil {
            panic(err)
        }
    }

    for _, row := range data2 {
        err := writer2.Write(row)
        if err != nil {
            panic(err)
        }
    }

    writer1.Flush()
    writer2.Flush()
}
