Golang determines whether it is a file or a folder

Go language method to determine whether it is a file or a folder:

// 判断所给路径文件/文件夹是否存在 
func Exists(path string) bool {  
    _, err := os.Stat(path)    //os.Stat获取文件信息  
    if err != nil {  
        if os.IsExist(err) {  
            return true  
        }  
        return false  
    }  
    return true  
}  
  
// 判断所给路径是否为文件夹  
func IsDir(path string) bool {  
    s, err := os.Stat(path)  
    if err != nil {  
        return false  
    }  
    return s.IsDir()  
}  
  
// 判断所给路径是否为文件  
func IsFile(path string) bool {  
    return !IsDir(path)  
}

isdir:

Function: Determine input (string) Whether to represent a folder. This function can also be used to determine whether a folder exists.

Syntax format:

tf = isdir('A')

If A is a folder, return logical 1 (true), otherwise return 0 (false).
