Printing 2 statements on the same line
问题
我已经成功制作了一个爬虫，可以爬取 eBay 上 iPhone 部分的所有 109 个页面。
问题是我需要将它们打印在同一行上。目前的情况是这样的
package main
import (
"fmt"
"github.com/gocolly/colly"
)
func main() {
c := colly.NewCollector(colly.UserAgent("Mozilla/5.0 (X11; Linux x86_64; rv:108.0) Gecko/20100101 Firefox/108.0"))
c.OnHTML(".s-item__title", func(element *colly.HTMLElement) {
element.ChildAttr("heading", "role")
fmt.Println(element.Text)
})
c.OnHTML(".s-item__price", func(element *colly.HTMLElement) {
fmt.Println(element.Text)
})
c.Visit("https://www.ebay.com/sch/i.html?_from=R40&_nkw=iPhone&_sacat=0&_pgn=1")
}
甚至无法在这些信息之间进行导航。有人能告诉我如何在同一行上获取标题和价格吗？
我考虑过重命名元素，但没有成功。
我可以使用 printf 或 println，但它们只会将所有内容一起打印出来。
英文:
I've successfully made a scraper that scrapes all 109 pages of the iPhone section on eBay.
The problem is that I need them to print on the same line. This is what it currently looks like
package main
import (
"fmt"
"github.com/gocolly/colly"
)
func main() {
c := colly.NewCollector(colly.UserAgent("Mozilla/5.0 (X11; Linux x86_64; rv:108.0) Gecko/20100101 Firefox/108.0"))
c.OnHTML(".s-item__title", func(element *colly.HTMLElement) {
element.ChildAttr("heading", "role")
fmt.Println(element.Text)
})
c.OnHTML(".s-item__price", func(element *colly.HTMLElement) {
fmt.Println(element.Text)
})
c.Visit("https://www.ebay.com/sch/i.html?_from=R40&_nkw=iPhone&_sacat=0&_pgn=1")
}
It's not even possible to navigate around this information. Can someone show me how I can get the Title along with the price on the same line?
I thought about renaming the element but it didn't work.
I would use printf or println, but then it just prints everything together.

fmt.Println()在末尾包含了\n，ln代表换行。如果这是你的问题，你可以使用fmt.Printf()来按照你想要的格式输出，它不会强制换行。
英文:
The fmt.Println() includes '\n' at the end. ln means new line. You can use fmt.PrintF() to format output however you want, it doesn't force a new line, if this is your issue.

尝试使用fmt.Print而不是fmt.Println。
package main
import "fmt"
func main() {
{
fmt.Print("Title")
}
{
fmt.Println("| Price")
}
{
fmt.Print("Title")
}
{
fmt.Println("| Price")
}
}
英文:
Try using fmt.Print instead of fmt.Println
package main
import "fmt"
func main() {
{
fmt.Print("Title")
}
{
fmt.Println("| Price")
}
{
fmt.Print("Title")
}
{
fmt.Println("| Price")
}
}
