Quickly learn to convert strings to arrays in Go language

In Go language, conversion between strings and arrays is a common operation. Especially when processing data, you often encounter situations where you need to convert a string into an array. This article will introduce how to quickly learn to convert strings to arrays in Go language, so that you can easily deal with similar problems.

In the Go language, we can use the Split function provided by the strings package to split a string into an array according to the specified delimiter. The following is a sample code:

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "apple,banana,orange"
    arr := strings.Split(str, ",")
    
    fmt.Println(arr)

    for _, v := range arr {
        fmt.Println(v)
    }
}

In this code, we first define a string str, which contains the names of three fruits, using commas as delimiters. Then use the strings.Split function to separate the string str by commas to get an array arr containing the names of the fruits. Finally, we print out each fruit name by looping through the array.

Run the above code, you will get the following output:

[apple banana orange]
apple
banana
orange

As can be seen from the output result, the string is successfully converted into an array, and the string is split into each element of the array.

In addition to using the Split function provided by the strings package, we can also use the strings.Fields function to split the string according to spaces and obtain an array containing words. The following is a sample code:

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "hello world welcome to Go"
    arr := strings.Fields(str)
    
    fmt.Println(arr)

    for _, v := range arr {
        fmt.Println(v)
    }
}

In this code, we define a string str, which contains several words in a sentence, using spaces as separators. Then the string str is separated by spaces through the strings.Fields function to obtain an array arr containing words. Finally, we print out each word by looping through the array.

Run the above code, you will get the following output:

[hello world welcome to Go]
hello
world
welcome
to
Go

Through the above example code, I believe you have mastered the method of converting string to array in Go language. When you encounter similar problems, you can flexibly use the functions provided by the strings package to split and convert strings, making your code more efficient and concise.

I hope this article will be helpful to you, and I wish you make more progress in learning and using the Go language!

go语言有没有缩进go语言有没有缩进Dec 01, 2022 pm 06:54 PM

go语言有缩进。在go语言中,缩进直接使用gofmt工具格式化即可(gofmt使用tab进行缩进);gofmt工具会以标准样式的缩进和垂直对齐方式对源代码进行格式化,甚至必要情况下注释也会重新格式化。

go语言为什么叫gogo语言为什么叫goNov 28, 2022 pm 06:19 PM

go语言叫go的原因:想表达这门语言的运行速度、开发速度、学习速度(develop)都像gopher一样快。gopher是一种生活在加拿大的小动物,go的吉祥物就是这个小动物,它的中文名叫做囊地鼠,它们最大的特点就是挖洞速度特别快,当然可能不止是挖洞啦。

tidb是go语言么tidb是go语言么Dec 02, 2022 pm 06:24 PM

是,TiDB采用go语言编写。TiDB是一个分布式NewSQL数据库;它支持水平弹性扩展、ACID事务、标准SQL、MySQL语法和MySQL协议,具有数据强一致的高可用特性。TiDB架构中的PD储存了集群的元信息,如key在哪个TiKV节点;PD还负责集群的负载均衡以及数据分片等。PD通过内嵌etcd来支持数据分布和容错;PD采用go语言编写。

go语言能不能编译go语言能不能编译Dec 09, 2022 pm 06:20 PM

go语言能编译。Go语言是编译型的静态语言,是一门需要编译才能运行的编程语言。对Go语言程序进行编译的命令有两种:1、“go build”命令,可以将Go语言程序代码编译成二进制的可执行文件,但该二进制文件需要手动运行;2、“go run”命令,会在编译后直接运行Go语言程序,编译过程中会产生一个临时文件,但不会生成可执行文件。

go语言是否需要编译go语言是否需要编译Dec 01, 2022 pm 07:06 PM

go语言需要编译。Go语言是编译型的静态语言,是一门需要编译才能运行的编程语言,也就说Go语言程序在运行之前需要通过编译器生成二进制机器码(二进制的可执行文件),随后二进制文件才能在目标机器上运行。

go语言怎么删除字符串字符go语言怎么删除字符串字符Dec 09, 2022 pm 07:19 PM

删除字符串的方法:1、用TrimSpace()来去除字符串空格;2、用Trim()、TrimLeft()、TrimRight()、TrimPrefix()或TrimSuffix()来去除字符串中全部、左边或右边指定字符串;3、用TrimFunc()、TrimLeftFunc()或TrimRightFunc()来去除全部、左边或右边指定规则字符串。

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
