如何从行中删除\ n [英] How remove \n from lines

问题描述

file, _ := os.Open("x.txt")
    f := bufio.NewReader(file)

    for {
        read_line, _ := ReadString('\n')
        fmt.Print(read_line)


        // other code what work with parsed line...
        }

在每行末尾添加\ n，结束程序正常工作，仅在最后一行工作...

end it add \n on every line , end program to work , only work with last line...

请举个例子，我尝试任何解决方案都无法解决我发现的问题.

Please put example, i try anything end any solution what i find here not work for me.

推荐答案

您可以分割最后一个字符:

You can slice off the last character:

read_line = read_line[:len(read_line)-1]

也许更好的方法是使用字符串库:

Perhaps a better approach is to use the strings library:

read_line = strings.TrimSuffix(read_line, "\n")
