Use the strings.Split function to split the string into multiple substrings according to the specified delimiter

In Go language, we can use the Split function in the strings package to split the string according to the specified delimiter. Split into multiple substrings. This is very useful when working with strings, especially when we need to split, parse, or extract specific content from the string.

The prototype of the Split function is as follows:

func Split(s, sep string) []string

Among them, s represents the string that needs to be split, and sep is used Delimiter to separate strings. This function returns a slice consisting of split substrings.

Let's look at a specific example demonstrating how to use the Split function for string splitting.

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "apple,banana,orange"
    separator := ","

    // 使用Split函数将字符串拆分成多个子串
    result := strings.Split(str, separator)

    // 遍历切片并输出结果
    for _, s := range result {
        fmt.Println(s)
    }
}

In the above example code, we defined a string str as "apple, banana, orange" and a separator separator as ",". Then, we called the Split function to split the string str according to the separator separator.

Finally, we use a for loop to traverse the split substring slice result and output each substring through the fmt.Println function.

When we run the above code, we will get the following output:

apple
banana
orange

As we can see, the Split function is used to split the string into three sub-strings according to the specified delimiter. String "apple", "banana" and "orange".

It should be noted that when the Split function splits a string, the delimiter itself will be used as the mark of splitting, but it will not be included in the split substring. In the above example, the separator "," does not appear in the output.

In addition, if no delimiter appears in the string, the Split function will return a slice containing only one element, which is the original string itself.

To summarize, using the strings.Split function can easily split a string into multiple substrings according to the specified delimiter. This is very useful when working with strings, especially if you need to split, parse, or extract specific content. Whether it is a comma, space, semicolon, or other specific custom delimiter, you can use the Split function to split the string.
